Rocking On In Career Transition

Hello Dear Readers!

Whenever I'm asked, "Do you want the good news or the bad news?" I choose to receive the bad news first. There are two reasons for this. One, I want to know the exact nature of the challenge I must face. This appeals to the collections manager in me, as a lot of what I did as a collections manager involved picturing plausible threats to the fossils for which I am a steward, and then doing my best to mitigate those threats. Two, I am pretty good at turning the good news I receive second into an opportunity to mitigate the bad news. So for this particular post about my in-progress transitioning from Collections Manager & Curator to ????, I'm going to start with the "bad news."

There is still no long-term solution for the continuation of the Peace Region Palaeontology Research Centre since the Tumbler Ridge Museum Foundation's (our parent non-profit organization) funding for 2018 was denied by the District of Tumbler Ridge in March.

This is the definite low point of the year for paleontology in our part of the world (northeast British Columbia), and this particular low point brought friends. The first Low-Point Tag-Along is the imminent threat to the continuation of the fossil archives (a.k.a. collections) at the PRPRC. Anyone who follows my Twitter account (@Lisavipes) has seen me tweet with some ferocity and vigor on the importance of stable, well-supported natural heritage archives. This isn't for self-serving reasons: museum archives are still poorly understood and little appreciated by the public (although I see this changing) and by the administrators who decide which areas of museum life get support (that I do not see changing as quickly as I would like).

I'll share one of my Twitter threads on the importance of supporting natural heritage archives here.
This tweet and the associated thread describe why the collections are the foundation of a museum's activities: educational outreach, high-profile research, student opportunities, marketing, displays. Sure, you can have an interpretive center that shows some nice displays of, say, birds in your area (also part of our natural heritage), but all of the information that goes along with the visual imagery of the display originates from research and a collections facility.

(Anyone familiar with my Twitter feed also knows that I communicate in gifs. True Story.)
The "who what where when why and how" of those birds was figured out from a bird scientist (a.k.a ornithologist) looking at birds in the wild and in a museum's collections. Collections don't just preserve individual specimens: they preserve patterns. Collections reveal to you what birds were once common in an area, but are no longer common. Collections reveal that what we thought was one bird was actually two really similar-looking species after the genetic information was studied. Collections preserve specimens collected throughout the years so we can see what toxins might be contributing to the decline of a bird species.

What us scientists call research is really just us figuring out the detailed story of the critters that we study. The collections are the library of ideas and information that make the story (scientific papers, displays, educational programming) possible.
We don't really describe the step-by-step detail of how discoveries are made. We usually present the Highlights version of the journey because, let's be brutally honest here, reading about the step-by-step, day-to-day grind of data collection, data analysis, surveying, etc. would be a tedious read. When I was a graduate student, our lab would informally hold a "Tedious-Off" competition. The person doing the most tedious task to tell the story of their fossil research would "win." There were no prizes, but we did get to share with our colleagues some of the slogging that we did to get from idea to science story. Common Tedious-Off entries were editing noise out of 3D model images, finding the one bad data entry in a spreadsheet of 10,000 entries, and counting all of the bumps on the cutting surface of a theropod tooth (that one never won, because we were looking at an actual specimen so that was still cool.) TL:DR is that collecting information and getting the story ready to tell isn't all excitement and surprised gasping at discoveries.
When I document fossil bird footprints on rock slabs, it's a pretty mellow scene.

Take a look at the above picture. This is a small part of the large bird and dinosaur track surface of the Gajin-ri Track Site in South Korea. The paleontologists who study this site made a trackway map (basically a drawing of all of the footprints as they appear on the surface) by spending hundreds of hours crouched on the surface finding and tracing each individual footprint in low-angle light. This is the standard operating procedure for studying small tracks. I've spent many a day in collections, pitch black save for one lamp, lying on foam pads on the concrete floor as I trace out bird tracks and invertebrate burrows on to plastic sheets.

I can't speak for everyone, but for myself, I am not looking for a new discovery when I'm documenting tracks. I'm simply transcribing what I see on to plastic and paper. It's only when I keep seeing the same "different" thing over and over that my brain starts to think "Hey, that's odd. something's going on here." It's not scientific montage process typically shown in movies, where scientists are looking for X, struggle to find X, and then - against all odds - find X. Perhaps this is why collections do not receive the respect they deserve: their use (except for display specimens: those are part of the collections) is behind the scenes and progress is careful and slow.

A curiosity question for me: is there anyone out there that would truly be interested in seeing an unedited video of a researcher like a paleontologist doing the Tedious-Off portion of their work? My working hypothesis is that the answer to that question will be chirping crickets.

When I gave the occasional tour of the collections facility, there are one of two reactions:

"Oh my God this is so important! Look at all of our heritage!"

...or...

"So how can we make money off of this?"

Maia demonstrating the Head Blanket, because sometimes Head Desk is too hard.
When I attempt to explain to this type of responder with how collections are the source of the displays and discoveries, I see eyes glaze over. I have not yet found the right combination of words that can break through this attitude.

As a result, I am now faced with the very real scenario of having to find a stable home for the fossil archives. We do not "own" the fossils. The town does not "own" the fossils. They are technically the property of the Province of British Columbia, and my colleague (and fellow termination notice holder) and I are the qualified stewards of the fossils.

The second Bad News Tag-Along is that there will be no paleontology field exploration done this summer. One misconception that I encounter is that field paleontology is cheap/free to do. This might be because the field survey methods are not necessarily high-tech. Fuel to get to field sites costs money. If you find something large, moving that specimen costs money. Also, our time has a cost associated with it. Just as artists can't pay the bills using Exposure Bucks, paleontologists can't pay the bills using Excitement of Discovery Bucks. And no, despite what people believe, making big discoveries does not make it easier to find funding to continue work. Media exposure =/= money in paleontology.

So, those are the Bad News items. Now on to the Good News items.

1. Tomorrow is my one year Bird Glamourversary! To celebrate this milestone in my journey as a science communicator, I will be launching a Bird Glamour YouTube channel that will combine me applying the Bird Glamour looks with cool facts about the featured bird! Once the link is live I will include it in this blog post!

UPDATE: Here is the link to the Bird Glamour YouTube channel!


2. I am working on two non-fiction book proposals! One book is purely in the proposal stage, while the other book has a couple of sample chapters already written. When I feel a bit more certain about the process and the progress, I'll talk about those projects here!

3. I am collecting the information I need for gaining certification as a professional geoscientist in British Columbia. It's a long process, but with the combination of schooling and 15 years of experience as an active paleontologist, I think that I have a great chance at succeeding.

4. I will be working on some post-secondary program development. Once the details of that project are ironed out, I can talk a bit more about the projects.

5. Of course, I am applying for jobs. I'm constantly reminding myself that it is not my job to tell myself I'm not right for a posted position...within reason, of course: I'm not going to apply for a physics or a botany position. I am making a conscious effort not to select myself out of potential opportunities.

That is my life in the sciences at this point in time! I am excited that I have the opportunity to explore options and opportunities within science communication through Bird Glamour and book writing.  Who knows where these opportunities will lead?

Bird Glamour and Scicomm: The Almost One Year Review

Hello Dear Readers!

I'm not going to try to gloss over the situation, but March and April have been less than glamorous. The District of Tumbler Ridge denied the annual operational funding request of our parent organization, the Tumbler Ridge Museum Foundation, because...well, I'm not really sure why Dear Readers. The reasons we are given (and that are stated in the media) keep changing in moving goalpost fashion. There's potential for a "because...Reasons" meme here. So, I'm sitting here with a termination notice in my pocket (the TRMF had no choice but to issue all of its employees, including me, the notices.) I'm not done writing about this, but that will be a future post, and one filled with more information than the "because...Reasons" that we have been given. Stay tuned.

This development happened in conjunction with a series of talks me and my colleague Dr. Richard McCrea gave in Vancouver and on Vancouver Island. First, we helped open the Beaty Biodiversity Museum's newest permanent exhibit Footprints In Time (link to the Beaty Biodiversity Museum website here) on the University of British Columbia campus. This was an excellent partnership: we made the trackway replicas, and then worked with their display and scicomm team to create the interpretive text. The displays look spectacular! Below is a picture of one of the trackway replicas, a 130 million-year-old track slab from northeast British Columbia that contains the natural cast (track infills) trackways of a large theropod (likely an allosaurid) and an ornithopod (likely similar in size and shape to Iguanodon.) That evening Rich gave a talk on dinosaur tracks from British Columbia (with a focus on the Six Peaks Dinosaur Track Site, follow the link for our YouTube video) for the Beaty Biodiversity Museum's Nocturnal lecture series.
One of three dinosaur trackway slab replicas (original specimens currently curated at the PRPRC) now on display at the Beaty Biodiversity Museum on the University of British Columbia campus!
I gave four talks over two days at Science World in Vancouver (that may also be the subject of a future post), and then I gave a presentation on what we know about dinosaur behavior from tracks and traces (a.k.a. ichnology) for the Beaty Biodiversity Museum's "Way Cool" series. Then we gave talks on track research in British Columbia in Courtenay for the Vancouver Island Paleontological Society.

Whew.

I can now talk about the subject of this post, which is my reflections on my almost one year anniversary of when #BirdGlamour took flight! Bird Glamour is a scicomm and sciart project that I developed to introduce people to the wonderful diversity and life history of our present-day theropods, a.k.a. birds, using a rather unconventional medium...COSMETICS!

My most recent #BirdGlamour is the Osprey (Pandion haliaetus)!
Each Bird Glamour post comes with a cool fact about the life history of the subject bird, ranging from migration to food preferences to feather pigments: basically, any tidbit of information that I think people would connect with. I launched Bird Glamour on June 9, 2017, with a very simple post.
To be honest, I had no idea how the linking of ornithology with cosmetics would be received. Some people in science are not exactly open to the idea of Science Selfies; however, read the strong rebuttal to this on the blog From The Lab Bench entitled "Why We Scientists Do Instagram." My concerns were unfounded. Bird Glamour is a hit!

There have been great highlights in the short life of Bird Glamour. One was my first video tutorial, developed with Audubon, for a Halloween-themed Bohemian Waxwing Bird Glamour!

I was also asked to do a promotional Bird Glamour for The Urban Interface, a non-profit wildlife and nature education center. They have lovely wildlife Ambassadors for which they care and train for educational purposes. Their Ambassador Pandora, a Swainson's Hawk, is a lovely Bird Glamour model.
Now that I'm nearing the one-year Glamour-versary (oh yes, I went there) of Bird Glamour, I wanted to fly a few ideas past Twitter to see if some new styles or techniques would ruffle any feathers. I went to the polls!

1. Most respondents were quite eager to see me migrate to other continents to glam it up!
I definitely agree! There are so many exciting birds and cool bird diversity to explore!

2. In addition to my usual style of Bird Glamour, people are interested in seeing me do makeup tutorials while I chirp about the bird being glamoured!
YouTube will be a new adventure for me. I'll admit that I feel nervous on camera. I also recognize that I shouldn't feel this way: I've been interviewed many times for documentaries and media. I'm hoping this nervous feeling will fade with familiarity.

3. There is interest to see how these Bird Glamour looks could be transformed to every day looks, or at least a fun evening look!
I will definitely experiment with everyday Bird Glamour looks. I am not an expert in applying cosmetics, so if you're also new to makeup, we can learn (and possibly laugh) together.

4. This poll on incorporating female coloration into Bird Glamour was almost neck-in-turkey-neck. To date, the looks have focused on male plumage (or those birds that have similar male and female plumage).
I agree with keeping the male and female plumage colors separate. However, I will glamour cases of gynandromorphism, the condition where an animal shows both male and female characteristics. Animals with bilateral gynandromorphism look male on one side and female on the opposite side. A recent case of bilateral gynandromorphism that hit the bird news was the gynandromorph Northern Cardinal.

 5. My last question involved beak color. Given the array of lipstick colors available, I think people wouldn't mind part of my makeup bill being used for Bird Glamour lipstick!
You'll be proud of me, Bird Glamour fans: I have started acquiring fun lipstick colors!
I also did my first Bird Glamour post that includes lip color: the Herring Gull.
Gulls are the perfect bird for incorporating lips into the Bird Glamour look. Many species of gull have a fairly standard adult head color - grey-white - but there is color variation in the stripes and spots on their beaks!

Reception of Bird Glamour

 Online Reception - The sheer number of positive comments and encouragement online is both staggering and humbling. I am thrilled that Bird Glamour speaks to people. Science art (sciart) is a powerful tool in science communication: there's a reason for the saying "A picture is worth a thousand words." Images are a powerful and effective way to transmit complex ideas. The idea of Sketchnoting relies on the information-delivery power of illustrations to highlight key concepts. Using a different style of illustration - makeup - allows me to highlight birds that people might want to know more about.

Bird Glamour also starts some great conversations about bird lives and biology. The most frequently asked question is "Why do so many birds have a black stripe around their eyes?" That's a good question! There was a study done on what the Masked Shrike uses its bold black eyeliner for. Is it to reduce glare for hunting? Does it make the eyes of the shrike appear bold and scary to deter predators? Does it help the shrike camouflage itself for sneak attacks, or hide the eyes so its prey doesn't know it's being watched? When researchers temporarily painted some Masked Shrike's masks from black to white (they Bird Glamoured an actual bird!) the shrikes with white eye masks had more trouble snagging prey and did most of their hunting facing away from the sun. It turns out black eye masks act as sunglasses for birds, at least for Masked Shrikes.

Public Reception - How do people react when they see me in public all Bird Glamoured up? It depends on the setting. I did a Bird Glamour version of the feathered theropod Anchiornis huxleyi, know for its striking black, white, and rusty red plumage, for attending the Society of Vertebrate Paleontology Annual Auction.
I had several people who approached me to say they enjoyed the Anchiornis Bird Glamour. There were also some smiling looks, but perhaps starting the conversation of "Hey, why is your makeup like that?" felt too socially awkward for them. I completely understand. Starting conversations with people I don't know is difficult for me as well. Running up to people, waving my arms and shouting "HEY WANT TO TALK ABOUT MY EYES AND ANCHIORNIS?" seems a bit intense, so I need to work on that approach. There were also some unsmiling stares and quick look-aways. That I also understand: Bird Glamour doesn't have to appeal to everyone. Or perhaps they thought I was unprofessional or strange. Well, as my readers and social media friends know, I am strange, but I am completely comfortable with expressing my interests and passions.

Family audiences are very receptive to Bird Glamour. When I did a presentation for families at the Goseong Public Library on Cretaceous bird track types found in both Canada and South Korea, the public reception was great! I had my picture taken with a lot of families! The people in the makeup department at our closest Shoppers are also interested: more than once I've gone in with a picture of a bird and asked "I'm looking for this color. Do you have anything like this?" On seeing some of my Bird Glamour posts, one commented: "Wow, so you're an artist!" That took me by surprise: I have never identified as an artist before. I can pencil sketch with enough accuracy to satisfy my eye, but art is not something that I have ever done professionally. All I could do was stammer for a bit and then say "Huh. Yeah, I guess I am!"

I am planning something super fun for my official one-year Glamour-versary in terms of setting and the bird, and a great bunch of Bird Glamour pictures to share from our West Coast trip.

What birds would you like to see for future Bird Glamour pictures? Do you have a science specialty that would make a great Glamour? Itati (@itatiVCS) has started #EcoGlam #MachineFacts to share how she uses various equipment to do ecology research! I'm going to enjoy following this hashtag!
Stay tuned for more Bird Glamour!

Tracking Cretaceous Birds in South Korea: Goseong Public Library Talks

Hello, Dear Readers!

We've made it to September 16, 2017, when our Ichnology Heros are scheduled to give talks to the public at the Goseong Public Library! When we go to another country to do research, we always offer to give a local talk on the work we do in Canada, and how the local fossil record fits in with our work on a global scale.

Giving a talk in another country where the language is not your primary language is not that different (in my experience) than tailoring an academic talk to a public audience:

1. Keep the jargon to a minimum. There's always a way to explain even a highly technical test or feature using non-technical language.

2. You may understand your graphs, but remember: you've been staring at them for months or years. No blob of ambiguous data points on a graph with itty-bitty axes, no series of fifty graphs that only have really subtle differences. If you use graphs, make sure the meaning of the graph is crystal clear.

3. Pictures are worth a thousand words. If you can describe it, see if you can also show it. Outline hard to see details for your audience. If you're showing a picture of a single bone or a footprint, also show an image of the animal it came from (or the closest representative).

4. Remember - especially when your audience is in another country - that jokes/witticisms are often colloquial and have local or specialized meaning. it may fall flat. Also, "those jokes" (which are really just methods used to belittle groups who have less representation and/or power) about gender, race, jokes about sex, sexual innuendos, or sexual imagery, or jokes about political situations are in really poor taste, no matter your audience. They have no place in a talk communicating science to any audience. No one wants to see that nonsense.

5. If a translation is necessary, remember that this will (at least) double the time it takes to give your talk. Make sure you are not talking in huge paragraphs: your translator is going to have to remember what you've said and be forced to summarize your long rambling monologue to a more concise sentence or two.

We were told ahead of time that the audience would be a mix of children and adults, so I made sure to travel with my Bird Glamour makeup kit! I don't often have an opportunity to do a Bird Glamour for an extinct species of bird or avian theropod (although I did rock Anchiornis at the 2017 Society of Vertebrate Paleontology meeting during the auction/social event!) I was excited to do an ichnology-themed Bird Glamour.

This ichnology Bird Glamour was inspired by Ignotornis gajinensis, the bird trackways that have spoonbill-like "swooshes" preserved. These "swooshes" are similar in shape to the bill marks made on sediment by present-day spoonbills stirring up the sediment to catch fish and invertebrates.
Spoonbill with its namesake spoon-shaped bill.

I decided to go with the Black-faced Spoonbill for this Bird Glamour. We arrived at the Goseong Public Library after a nice lunch with the Library's curator, public programming coordinator, and some of the Library staff.
The poster advertising our public talks at the Goseong Public Library!
While the rest of the Ichnology Team had coffee and snacks with the curator, I applied my Black-faced Spoonbill look.

These looks can take anywhere from twenty minutes to an hour to create. Once I was done, Sujin asked if I could do her eyes up as an owl. Sujin chose a Long-eared Owl, and I was kindly given the use of the curator's office to apply Sujin's Long-eared Owl look.
Me (left) with Black-faced Spoonbill eyes and Sujin (right) with Long-eared Owl eyes. 
This was the first time I had given a public talk while wearing Bird Glamour. I admit to being a trifle nervous about it: people sometimes have a very specific stereotype image in mind when they think "scientist," and that image does not typically involve makeup, let alone bird-inspired makeup. Nevertheless, I opened my talk by introducing Bird Glamour and used the link between the Black-faced Spoonbill and Korea's fossil bird tracks to talk about the bird tracks of western Canada.
Dr. Martin Lockley talking about his track work in South Korea.
Dr. Richard McCrea talking about dinosaur tracks from western Canada.
The talks were very well-received: there were a lot of interesting questions from both the kids and adults in attendance. We went out for our last dinner in South Korea: bulgogi! After dinner, we went to Dr. Kim's lab for one last push to get as many tracks documented in our time remaining. We were at the lab until at least 11:00 pm local time.

Our flight from the Incheon Airport wasn't until the early afternoon, but we were scheduled to take a bus from Jinju to Incheon. The bus was scheduled to leave Jinju around 5:45 am. We were up, packed, and waiting in the hotel parking garage for our ride to the bus station at 5:10 am.

Things got...interesting. We saw some of the Jinju night-life as young people started returning home from what I assume was a fun Saturday night. Then a young woman staggers down the road. She is still in a partying mood and is very eager to give us cigarettes. She tells us in her limited English that she is from Russia, and that she doesn't speak [insert derogatory term here]. To directly quote my field notes from that morning "Charming that one of the few English words she knows is a slur. :| " While this interaction was taking place, I was scanning down the road to make sure that she was not distracting us so that an unseen companion could rob us. Before long Sujin arrived with an additional cab to take us and our luggage to the bus station. Rich gave his gift of cigarettes to our cab driver.

We arrived with plenty of time to get our boarding passes for the bus. These buses are glorious: truly comfortable seats with nice headrests and copious leg room. We slept until our rest stop about halfway between Jinju and Incheon Airport. We breakfasted on roasted chestnuts purchased at the concession. If you've never had roasted chestnuts, they have a soft texture that is slightly sweet.
Since all of the buses look the same, we made sure to remember in which space our bus was parked. 
We arrived at the airport with plenty of time to spare. This was good because it gave us a chance to repack our bags to make sure we didn't have power sources, like a solar battery charger, in our carry-on luggage. We found this out when Martin (who was flying out of Incheon first) was pulled out of line during his bag scanning to repack his bags. Oops. You can travel a million times and still miss an item or two.

Our flight back to Canada was uneventful, which is the best kind of flight! Usually, on a flight and while waiting in airports I type away on writing projects and papers. Sometimes I try to read if the jetlag isn't too powerful. I felt the jetlag start to hit me hard while we were waiting for our flight from Vancouver to Fort St. John. Jetlag gives me a very disconnected feeling: I feel as though I'm moving at a different tempo than that of the rest of the world. I also tend to feel as though all of my sensations have been muted.

Then, of course, there's the struggle to reclaim your original sleep schedule. This can take anywhere from a couple of days to over a week. My advice: don't try to do a hard reset on your sleep schedule. Day Three after we had arrived home, we forced ourselves into a "normal" day by doing a day trip into another community. We were out of the house at 9:00 am and in bed around 11:30 pm. The next thing we knew, we were waking up the next day at 3:45 pm. Just let the jet lag run its course.

That is the end of our tracking adventure in South Korea! Now we have several scientific papers to write on all of the data we collected! Hopefully, I'll be able to give you updates on those papers soon!

Tracking Cretaceous Birds in South Korea: Goseong Dinosaur Tracks

Hello Dear Readers!

I'm excited to continue with our tale of Cretaceous tracks in South Korea! September 15 was our day to check out the coastal dinosaur track sites in Sangjogam County Park, a heritage site. This was a track site that Dr. Richard McCrea had visited back in 2000 on his first trip to South Korea. He said to me "I did not expect that I would ever get a chance to visit this site again."

A LOT had changed since Rich's visit in 2000. At that time the area was newly discovered and in the process of being documented. Let's just say, the progress made on the site was impressive!

After breakfasting and grabbing some Starbucks (science runs on caffeine all over the world), we drove to the parking area next to the coastline. We were immediately greeted by a great sauropod sculpture surveying the gorgeous shoreline.

"I am Lord/Lady of all I survey!" said every sauropod everywhere.
The entire area around the Goseong Dinosaur Museum was developed to celebrate the dinosaur track sites. The sidewalks also celebrate their fossil heritage.
Getting ready leave the walkway to stroll along the beach to see the sauropod tracks.
Of course, a sandy beach is a glorious place to look for present-day bird tracks. Today was a day for gull tracks.
One of these days, I'll be able to afford a decent lens for photographing birds. September 15 was not that day. Neither is today, actually.
This was the best picture I could get of one of the gulls roaming around the beach that morning. It's carrying a mussel in its beak, so the appearance of a black ring on the bill is artificial. I also didn't pack my binoculars that day, so my identification of this gull is "gull." The gulls did leave some nice trackways.
The sand is damp enough that the webbing impressions are preserved. We can clearly see the claw impressions and occasional toe impressions.
There was also some interesting behavior exhibited by the gull tracks. Check out this landing trace of a gull: you can see the long drag mark left by the hallux (backward-facing toe) running down the middle of the scuffed-looking footprint. I used this image for my weekly Twitter ichnology game #NameThatTrack.

Of course, I couldn't spend all day on the beach taking pictures of modern footprints (although this would be a worthy ichnology project.) We made our way over to the Goseong Track Site.

The most obvious trackways on the site are sauropod trackways.
The circled areas are the sauropod tracks. Scalebar in the picture is 10 cm.
Close-up of the sauropod tracks with a 10 cm scale (and my feet) for scale.
While we were on the site, we found ourselves in the middle of a couple of school groups doing a geology-based field trip assignment and tour on the track site. We ended up being part of the tour, with the students watching us take photos and asking us questions. We also ended up signing autographs on their site brochures! That felt...odd. I mean, I was not involved with finding or developing the site, but I suppose they appreciated the chance to interact with dinosaur track scientists on the site.
Drs. Martin Lockley and Richard McCrea somewhere in the middle of the tour group!
There are several track types on the Goseong Track Site. Here is an ornithopod trackway, with the tracks outlined with dashed lines.

With coastal rock exposures, particularly those that are periodically covered by tides, we don't expect that tracks will "last" that long. Tides are powerful, running sand and shells over track surfaces. They also form tidal ecosystems: it's not uncommon to see dinosaur footprints doubling as tidepools. Given that tidal-influenced areas are generally high-energy, I was not expecting to see bird tracks at this site. I moved a little farther away from the shoreline to check out some fine-grained surfaces. I was not disappointed!
They are shallow, but there are small bird tracks!
It was an overcast day, so the light was fairly dim and there few shadows being cast on the track surface. These were great conditions for getting photogrammetry images of the sauropod and ornithopod trackways, but the dim light made seeing bird difficult. Like I've mentioned before, lighting is everything when it comes to recognizing tracks.

The Goseong Track Site was impressive for another reason: the level of resources and development that went into making the site accessible to the public. When I show these images, remember that only 17 years prior this area didn't have the track sites developed or a dinosaur museum built.

First, there are the extensive walkways built along the coastline so that people can look over the track surface. There are several kilometers of these walkways! At key points along the walkways are informative signs that direct visitors' attention to key geologic and paleontologic views.

Editorial Note: OK, friends, I need to go on a bit of a rant. Look at this sign. It gives out science information without talking down to the reader. Do you see any cheap, lazy Jurassic Park-themed lettering? Any sensationalized attempts to use giant waves in "storytelling"? You do not. I did not see ANY sign of the North American-style insulting "tourism marketing" in South Korea. This is because the organizations that made these signs actually respect the intelligence of the people who are visiting natural history sites. They don't assume that there is "too much science" in the information provided, or that the public needs to be "talked down to."  Each time I see a fossil heritage site that blatantly uses Jurassic Park imagery and/or sensationalized "stories" to interpret a site, I assume the organization that created those signs does not respect their visitors OR the fossil heritage they exploit. Respect for fossil heritage or those interested in natural history isn't even on the radar for those particular organisations: fossils are merely a thing to selfishly use, and the public are just their dupes with wallets. It makes me feel angry and ill. Oh, and the fact that, since Rich's 2000 visit, a museum and outdoor interpretive sites had been fully developed? It is extremely frustrating to see the slow progress of getting similar dinosaur track sites developed in North America. We've been in the Peace Region full-time since 2004 and we still struggle year-to-year to have fossil heritage conservation funded.

We hiked up to another track site that was not yet interpreted: one of the aspects of coastal geology is that it changes a lot, with new rock surfaces constantly being exposed. Rocky cliffs are also a tricky place to do ichnology, mostly because of the ever-present threat of those tracks using gravity to make face-time with you. Here are some bird tracks exposed on the underside of a rock exposure. We couldn't get a close-up view of them, but we could tell they were the ichnogenus Jindongornipes.
The preservation of these large bird tracks (Jindongornipes) is amazing! We can even see webbing impressions!
Rich attempting photogrammetry on the Jindongornipes tracks. It becomes more tricky when you can't get something for scale on to the track surface.
We continued our hike up from the coastline boardwalk to connect with the outdoor trails and displays of the Goseong Dinosaur Museum. Again we were treated to a glorious sight: great outdoor displays that did not shy away from interpreting science.
The boardwalk trail joins up to the Goseong Dinosaur Museum outdoor trails.
Um, friends? There's a Utahraptor watching you!
All of the outdoor dinosaur sculptures were time-appropriate to the age of the tracks exposed at the Goseong Dinosaur Track Site: Early Cretaceous in age, roughly 120-100 million years old. We did not see any Tyrannosaurus rex or Triceratops models, which are 66 million years old. This was another sign (to me) that the Goseong Dinosaur Museum wasn't relying on sensationalism (a.k.a. all cool dinosaurs are T. rex!) to interpret their fossil heritage.

The Goseong Dinosaur Museum also had some fun with their outdoor displays. I love this cartoon bird pointing out the names of the bird tracks.
We stopped for lunch with the Goseong Dinosaur Museum curator at the museum's cafe, and were treated to a wonderful beverage: quince tea that the curator made! We found out the recipe, but darn it! We can't seem to find quince anywhere in grocery stores. The hunt continues!

After lunch we spent some time in the collections facility of the Goseong Dinosaur Museum, collecting data, photogrammetry images, and track slab tracings.

Sometimes you meet the local fauna when you work on tracks. Here's a wolf spider, who was not impressed when I disturbed its cozy hideout. It was ceremoniously moved outside.

We worked until evening, and then went out for dinner at a restaurant whose name roughly translates to "The Broken Bone Restaurant." It was a great dish of stewed meat on the bone, served with fried rice.
The Broken Bone Restaurant. 
It's no secret that I like spicy foods. Do you see the green chilis on the dish to the left? Up until this point, I had been munching on these peppers like they were candy. Tonight was the night that I found out there are two types of long green chilis: mild and spicy. I caused a great deal of amusement as I sat there, eyes streaming, face flushed, laughing at my luck of the draw. I found out that the smooth-skinned green chilis are the mild ones, and the green chilis with wrinkled skin near the stem are spicy. Live and learn!

The next day we were scheduled to give public talks on our work in Canada and South Korea at the Goseong Public Library! Tune in next week to find out how our talks went!

Tracking Cretaceous Birds in South Korea: Chinju Innovation City and Sangcheong-gun

Hello, Dear Readers!

When we last left our heroes, they were finishing up a long day (September 13) of laboratory and field work in Chinju (Jinju) University and Bito Island, respectively. September 14 would also prove to be an exciting field- and museum- day, full of bird tracks! Don't worry: I won't forget the non-avian dinosaur and pterosaur tracks!

Once again I'm forced to break our day into the field component and the museum component because there is just so much to talk about. This week's September 14 post will cover our field activities, and the next post will cover the spectacular Gajin Track Site.

We start off our day with a 7:30am wake-up and met Sujin for breakfast at a local Starbucks around 8:30am. After breakfast, we met Dr. Kim Kyung-soo at the hotel and drove to one of the in-progress construction sites of Jinju Innovation City. Remember in my last post, when I said that one of the similarities between studying tracks in British Columbia and South Korea is that many discoveries were (and continue to be) made as a result of industrial activity? Jinju Innovation City is a perfect example of industry significantly contributing to paleontology discoveries.

Excavations are uncovering track surface after track surface, and with a mandate to preserve national heritage, paleontologists in South Korea have to not only archive these large track-bearing blocks, but they also have to collect them! In the spirit of "necessity is the mother of invention," Dr. Kim designed a novel method for removing and transporting track blocks weighing several hundred kilograms...in one piece. Oh yes: and every picture in which you see a "KS" label on a track specimen? That specimen was collected and documented by Dr. Kim Kyung-soo.
People with visible faces: Drs. Kim Kyung-soo (left), Martin Lockley (center) and Richard McCrea (right) examining one of Dr. Kim's amazing track cradles for a large specimen ready to be removed to collections.
When we have the resources, we are going to bring Dr. Kim and his team over to visit track sites in British Columbia: I would love to see his track slab cradle technique in action!

Not all of the track-bearing surfaces are removed. One of the great approaches we witnessed in South Korea (take note, North America) is that people recognize - and act on - the value of preserving track localities as interpretive sites to educate the public. At this one construction site, two interpretive buildings are under construction for small interpretive centers.


I am just going to add an editorial note: this is the Republic of Korea. The country has a population of in a land area of 51,446,201 (with a density of 507 people per square kilometer) in a 100,210 square kilometers. Land, and space on which to develop, is valuable, and yet the Republic of Korea STILL finds ways to preserve and showcase their fossil heritage with respect. Now look to Canada. We have a population of 35,151,728 people spread over 9,984,670 square kilometers (population density of 3.92 people per square kilometer, albeit concentrated near the border with the United States.) So how come there is so much reticence towards protective buildings such as this one installed over important fossil sites? Take your time.

The track surface is covered to protect it during construction, so we pulled back the layers of tarps and thick felt-like cushioning to visit the surface.
Vertebrate ichnologists LOVE seeing surfaces like this...these are great surfaces for tracks!
We swept off portions of the track site to reveal some tracks with exquisite detail. The track type that has fascinated me (let's be honest: they all fascinate me) are trackways of pterosaurs. Yup: tracks of flying reptiles! When they weren't soaring through the air, pterosaurs walked on surfaces as quadrupeds, leaving wing finger impressions! HOW COOL IS THAT?!?
A pterosaur handprint! Guess what the loooong digit impression is from? (Psst: it's the wing digit!)
Editorial Note: You may want to Google pterosaurs. I don't blame you: they are fascinating archosaurs! However, you may encounter two websites in your search. One is called "ReptileEvolution.com" and the other is called "Pterosaur Heresies," both of which are run by the same person. Both of these sites are full of interesting artwork, but the information they provide on "radical" new ideas about pterosaurs is not supported by information from the fossils. Neither site should be a go-to site for accurate, data-supported information. Read the Tetrapod Zoology blog post on the issue.

One part of Dr. Richard McCrea's work is to refine photogrammetry techniques, particularly with small, low-relief tracks. This little pterosaur handprint is a perfect test subject!
Dr. Richard McCrea takes photogrammetry images for creating a 3D digital model of small tracks.
With a surface that preserved detail like pterosaur tracks, I was very hopeful for bird tracks. I was not disappointed! We didn't have a lot of time at the site, so this is the only definite track I could see, but where there's one, there's likely more!
This isn't the best picture (the room was under construction and unlit) but it is very birdie!
We drove to Sangcheong-gun (Sangcheong County) to check out a track site that was relatively close to the highway. It was a HOT day: the track surface was almost burning hot. It was a great contrast to the raindrop impressions we saw.
Oh yes, that's a bird track in the center of all of those rain drop casts.
This was a lovely track surface for fine details. The bird tracks were exquisite. The bird track in the center of the image above has slight digital pads and a lovely hint of a webbing impression!
You know you have a nice track surface when fine soft tissue details, like skin impressions and webbing impressions, are visible!
There's a lot we can tell about this trackmaker by looking at its footprint. One, this is a small bird (footprint length about 2.5 cm). Two, it doesn't have a well-impressed hallux (or reversed toe), so we know it didn't look or behave like a small crane or egret. Three, this bird only has a little bit of webbing between the middle and outer digit: this isn't a webbed bird like a duck. Four, this bird meandered, stopped, and started again, all over the track surface. This bird, if we were to take a time machine back to the Early Cretaceous, would have looked and behaved a lot like one of our present-day sandpipers. This was another track site exposed by industrial activity (construction of a highway), although our time machine shows us a peaceful scene of a very quiet, silty bank next to a small lake or slow-moving stream.

Also, we would have had to watch out for being stepped on by sauropods! Another thing we know from the tracks is that the sauropod came through first, and then the birds walked on the surface. We know this because the bird trackway actually walks around the sauropod track! How cool is that?

We then drove to a small cafe where we would eat what would be my favorite meal in Korea: naengmyeon, cold noodle soup! (Note: this is only one of many recipes I found online.) Most of the soups we tried in Korea had two versions, a regular version and a spicy version (I went spicy!) This is now a soup I make regularly for dinner, or at least the closest version I can make living in a remote area with limited shopping options.

Stay tuned for our visit to the Gajin-ri track!

Sound Bites: Hearing a Tyrannosaurus rex

If you are a fan of dinosaurs, probably know what sound accompanies this image.


Watching Jurassic Park for the first time (and several times after that) introduced us to what Tyrannosaurus rex would be like, in their movements, behaviors, and sounds. This scene is never, ever going to get old. It was also perfect that my first viewing of Jurassic Park was at a drive-in during a rainstorm.

Hollywood is no stranger to using odd things to recreate visual and audio effects sounds with which we are familiar...or have no familiarity with at all because they haven't been invented yet (lightsaber swooshes), because we don't regularly stab people in the shower (chocolate syrup was used for blood in the original Psycho), or because the sound is so far in the past that no human has ever heard anything like it.

Elephant, tiger, and crocodile sounds were used to recreate the iconic Tyrannosaurus rex sounds. I am most interested in the use of the crocodile gurgling. In my opinion, especially as a person who has spent a lot of time in the wilderness and has heard countless mammal sounds, the crocodile gurgling of the Tyrannosaurus rex this is far more unsettling than the classic roar.



Hollywood gave us something terrible, awesome-sounding, and not-at-all-subtle for Tyrannosaurus rex because we, as human beings living in a time dominated by large fuzzy roaring mammals (lions and tigers and bears, oh my!), expect our large predators to roar, snarl, and bellow. Most of the animals used to create the classic sounds of the Jurassic Park Tyrannosaurus rex are large mammals.

Extant Phylogenetic Bracketing and the Sounds of Tyrannosaurus rex

Figuring out how an extinct mammoth sounds, or how an extinct species of large cat sounds, is not that difficult because we have large pachyderms and large felids around to use as examples. We use large mammals as a comparison against large dinosaurs because hey, that's what we have to work with. However, dinosaurs are not mammals. Dinosaurs belong to a group of animals called archosaurs. Archosaurs took a completely different evolutionary path from our group, the synapsids (mammals and mammal-like reptiles.) The archosaur group and the mammal-like reptile group have been doing their own things, evolutionary-speaking, for at least 250 million years.

Our present-day representatives of archosaurs are the crocodiles and the small theropods (a.k.a. birds). These animals are much closer to large non-avian dinosaurs in terms of evolutionary history, anatomy, and likely behavior, than are large mammals. Crocodiles evolved before large non-avian dinosaurs, and small present-day theropods (birds) became specialized after large non-avian theropods evolved. We have the beginning of the story (crocodiles) and the end of the story (present-day theropods), with large non-avian dinosaurs landing in the middle.

Using crocodiles and present-day birds to test hypotheses (questions) about extinct dinosaurs is called Extant Phylogenetic Bracketing. The present-day examples (crocodiles and birds) give us examples of what is possible for extinct animals (large theropods) that are also part of their group (archosaurs). A lot of the information we have on theropod dinosaur behavior comes from comparisons to the behavior of present-day birds, such as parental care and egg clutch sizes (Varricchio et al., 2008; Varricchio and Jackson, 2016) and potential courtship behaviors (Lockley et al., 2016).

Enter Dr. Julia Clarke, professor of vertebrate palaeontology at the University of Texas. She used extant phylogenetic bracketing to take two unsettling sounds (crocodile vocalizations and the booming call of the Eurasian Bittern), scaled them up to Tyrannosaurus rex-size, and....dang.



Here is the link to The Telegraph news article that contains a video playing the sound. I'll give you a minute or two to go and listen.

Was that not completely disconcerting? What if you were in the forest, and heard (or felt like the host mentioned) that sound behind you? I guarantee you'd have a case of the freakies: I know I would.

Humans have (when compared to the rest of the animal kingdom) a rather limited range of hearing. Humans, in general, can hear sounds between 20 Hz and 20 kHz. Sounds below 20 Hz are typically referred to as infrasound. Our species doesn't really hear infrasound all that well. Check out this link from the Cornell Lab's Elephant Listening Project. There are three sound clips at 10 Hz, 20 Hz, and 30 Hz. Can you hear the sound?

I could not hear any of the clips (I did feel pressure in my ears), but that's not surprising: I have not evolved to communicate using low-frequency sounds, unlike elephants and some birds (the link goes to a recording of a cassowary).

However, just because we (as a species) can't hear infrasound doesn't mean that some of us may not sense it in other ways. I felt a pressure in my ears when listening to the clips and afterward, I felt a low-grade headache. There have been studies done that suggest infrasound may induce feelings of unease in humans. One such study was the Purcell Room Concert of May 31, 2003. The audience listened to music, into which infrasound was inserted at specific times (the audience didn't know.) The audience was then asked to fill out a questionnaire detailing their experiences during the concert. To quote the webpage:

"During our concert, infrasound boosted the number of strange experiences reported among the audience, even among those who were unaware of its presence. Unusual reports included a sense of coldness, anxiety, and shivers down the spine. On average, infrasound boosted the number of strange experiences by around 22 percent. It also increased the intensity of any feelings reported."

Does this sound like any unexplained phenomena? Turn down the sound for this clip: it's a little loud.



There is a strong possibility that what people experience as a sign of a ghostly presence (coldness, anxiety, shivers, unease, etc.) could be their sensitivity to infrasound.

Here's a chilling thought: if Tyrannosaurus rex had part of its vocalizations in the low frequency or infrasound range, not only would we hear that menacing gurgle, but the vocalization would likely trigger an anxiety reaction during the encounter.

I'll leave you with this lovely clip of a vocalizing American Alligator. Have a Creepy Monday!
