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!
I’ve covered many of the North American ankylosaurs in my previous papers and blog posts. In 2013, I argued that what we thought was Euoplocephalus was more likely 4 taxa – Anodontosaurus, Dyoplosaurus, Scolosaurus, and Euoplocephalus proper. Then in 2014 we described a newankylosaurid, Ziapelta, from New Mexico. There are a few other taxa that had previously been proposed to be ankylosaurids, so let’s take a look at them here.
Last time, I talked about the ankylosaurids of China, and today we’re talking about Gondwanan ankylosaurs. Gondwana basically refers to the continents of today’s southern hemisphere; when the supercontinent Pangaea broke apart, it split into two large continents – Laurasia in the north, and Gondwana in the south. Gondwana includes South America, Africa, Australia, and Antarctica, and, somewhat nonintuitively, India (India kind of beelined into Asia from Australia and that’s why we have the Himalayas). Almost all of the ankylosaurs we know about are from the Laurasian continents, which means that the few found in Gondwana are phylogenetically and biogeographically interesting: do they represent southern branches of the ankylosaur family tree, or new migrations into Gondwana from Laurasia? Let’s take a closer look:
I’m in Utah digging up dinosaurs! But also, one of the last big chunks of my PhD thesis has just been published online at the Journal of Systematic Palaeontology. They are generously allowing free access to the paper through the end of August, so head on over and grab a copy while it’s free! This time, I’m taking all of the knowledge gained from my previous taxonomic revisions, adding in some more taxa, and doing a revised phylogenetic analysis building on previous analyses to see how everyone shakes out and to learn a little bit more about ankylosaurid biogeography. I’ll cover some of the taxonomic stuff over the next few posts, and finish off with the big picture of ankylosaurid evolution.
I have some Thoughts and Feelings about Jurassic World! Spoiler alert, I’m going to talk about details and plot points and this post is really for people who have seen the film. Also, while I’m going to talk about the dinosaurs a bit, this isn’t really a review of the science of the film, because that’s already been done to death. Ok, onwards and upwards into something that wound up being way too long!
Updated on July 8, 2015!
“Cornelius” now has a scientific name – Wendiceratops pinhornensis!
You can read the open access paper here:
Evans DC, Ryan MJ. 2015. Cranial anatomy of Wendiceratops pinhornensis gen. et sp. nov., a cnetrosaurine ceratopsid (Dinosauria: Ornithischia) from the Oldman Formation (Campanian), Alberta, Canada, and the evolution of ceratopsid nasal ornamentation. PLOS ONE 10:e0130007.
Say hello to Cornelius! I got to meet him during a brief visit to the ROM last week, and he seems like a pretty nice guy.
I love surprises. Which is unfortunate for me, because I am extremely bad at being surprised. And it’s hard to be surprised by things as you get older, and as easier access to more and more information becomes available to us every day.
But boy, when a surprise comes along that actually takes me by surprise, what a thing to be able to savour.
Dino Hunt Canada is almost here! Starting this Friday, History Channel Canada will be airing a series of hour-long documentaries devoted to dinosaur expeditions all across Canada – and not just in the famous badlands of Alberta! The production crew visited field localities in Nova Scotia, Saskatchewan, multiple places around Alberta, and British Columbia. It’s going to be a real who’s who and where’s where of Canadian palaeontology.
I’ll be in the second episode featuring work in Dinosaur Provincial Park, which we filmed in 2013. It was a fun if somewhat unusual experience to have such a large film crew with us, and I’m looking forward to seeing the whole shebang!
What was the crew filming in DPP? Tune in to find out!
There’s also a really excellent website to accompany the show. You can learn more about some of the dinosaurs featured in the series (including wonderful new artwork by Danielle Dufault!), see interviews with some of the palaeontologists, and submit ideas for a nickname for a new dinosaur excavated during the show by the Southern Alberta Dinosaur Project. You can even submit questions and maybe have my weirdo face answer them via Skype! All in all, it’s looking really good so far and I’m so happy to see the huge variety of dinosaur research being conducted across Canada by so many talented and hardworking people.
After a whirlwind couple of weeks with a bunch of international travel, I’ve finally had a chance to sit down and write about my most recent paper on the ankylosaurs of the Baruungoyot and Nemegt formations of Mongolia. I’ve been interested in these ankylosaurs for a long time now, both because of their interesting cranial anatomy and their relationships to the ankylosaurs of North America (especially Alberta). So, here’s a plain-language summary of some complicated taxonomy! Hooray! Continue reading
