Readers of this blog will not be surprised to know that I find ankylosaur tail clubs quite interesting. I’ve been lucky to get to study their biomechanics and whether or not they were plausible weapons, how their morphological variation helps us identify different species, and how they evolved in a stepwise manner, with the stiff handle evolving before the enlargement of the osteoderms at the tip of the tail. Occassionally it’s good to step back and just think about how *weird* it is that ankylosaurs modified their tails in this fashion, and how weird it is to have a weapon on the tail. Continue reading
It’s a New Paper Day today! Go check it out at the new open access journal FACETS!
An alternate title I kicked around for this paper was “Victoria thinks about Ankylosaurus for a while: What does she know? Does she know things?? Let’s find out!”, because in the end this represents lots of little odds and ends about the most famous of ankylosaurs accumulated since about 2008 until they felt like they gelled enough to make a proper paper out of. In this paper, Jordan Mallon and I tackle some of the more frustrating aspects of Ankylosaurus: what does this animal really look like, what’s up with its weird giant skull, and how did it live?
Here’s a copy of the World’s Fair Ankylosaurus at the Royal Alberta Museum before the museum’s move to the new building – I know it’s partner the Corythosaurus has moved to Jurassic Forest, but I’m not sure where this guy is winding up! Maybe he’ll be at the new RAM?
Just a quick update today, consolidating some video and audio interviews I’ve done over the past few months! Here’s Zuul again because why not!
Friends, there’s a new ankylosaur today! Meet Zuul crurivastator, the Destroyer of Shins, an ankylosaurine dinosaur from the Judith River Formation of Montana, published today at Royal Society Open Science. Zuul is known from an amazingly complete skeleton with preserved soft tissues and an absolutely killer tail club. Head on over to the official ROM Zuul site for photographs, illustrations, videos and more, and follow #DinoZuul on Twitter for updates from me, David Evans, and the Royal Ontario Museum.
I’m back from yet another whirlwind week of conferencing, since the annual Society of Vertebrate Paleontology meeting (this year in scenic Salt Lake City) just wrapped up last weekend. I’ll share some photos of the conference and welcome reception at the Utah Museum of Natural History soon, but today I’d like to talk a bit about who is giving talks at SVP and how we can increase speaker diversity. I hope you will share this with your colleagues and students! Continue reading
Hello blog friends! Today I’d like to highlight an important funding campaign that needs your help: Save Mongolia’s Dinosaurs! This campaign is organized by Bolortsetseg Minjin and Thea Boodhoo through the Institute for the Study of Mongolian Dinosaurs; you may have encountered Bolor’s name during the episode involving the Tarbosaurus auction in New York a few years ago, as she was the palaeontologist who initiated the investigation around the provenance of that specimen. Her actions helped lead to the repatriation of that specimen back to Mongolia. She does important work and is a palaeontologist you should know and support!
Pseudoplocephalus has a new home! WELCOME!
Over the many years I’ve spent thinking about ankylosaurs, I’ve amassed a not insubstantial collection of ankylosaur stuff. And one of the things that I’ve noticed is that when ankylosaurids are shown wielding their tail clubs as weapons, they are almost always fighting some kind of tyrannosaur (but usually Tyrannosaurus, of course). Are there any illustrations that show ankylosaurids fighting anything different?
Back in January I asked my Facebook friends and Twitter followers to look in their homes for ankylosaurs fighting things and to let me know what they found, and now, blog readers, I am asking the same of you! Find some ankylosaurs fighting something and either tweet it to me (@VictoriaArbour) or leave a comment below!
Here’s what the preliminary results from my January request look like! (And yes, there was one example of an ankylosaurid tail clubbing a human.) The data I get from all of you will help me develop hypotheses for better understanding the selective pressures that led to the evolution of tail weaponry in ankylosaurs. Have at it!
Ankylosaurs, like probably most other dinosaurs, were landlubbing, terrestrial animals without obvious aquatic adaptations. And yet, surprisingly, their fossils are found in marine sedimentary environments more often than most other dinosaurs (except hadrosaurs). Some, like Aletopelta, wound up in shallow or lagoonal environments – Aletopelta’s carcass became a reef! – but some, like the Suncor nodosaurid, wound up far away from shore.
Aletopelta! See if you can spot the oyster marks, invertebrates, and shark teeth around the pelvis and legs.
After the SVP meeting in Dallas, I spent a couple of days working on Texan ankylosaurs at the Ft Worth Museum of Science and History, and at the collections at Southern Methodist University. It was nice to see a bit of Texas outside of downtown Dallas, so here’s a few shots from my visit to Ft Worth!
Welcome to the Perot Museum of Nature and Science! The Society of Vertebrate Paleontology Annual Meeting’s welcome reception was held here last week. This museum is trying out some interesting and different exhibition ideas that I haven’t seen too often elsewhere, so let’s take a look at some highlights.
