@zihanshen115982 Beautiful!

Hard to believe it's been a whole year since Traskasaura was born into the world! The paper is available at the following link, or you can DM me for a copy: https://t.co/uZeAadfAGI. Stay tuned for more plesiosaur goodness on the horizon! 🧵7/7

Happy Traskasaura Day, everyone! Our paper describing this basal elasmosaur, the provincial fossil of #BritishColumbia, was published one year ago today. Read on for details about the visual choices we made to bring its reconstruction to life! 🧵1/7

We did not reconstruct our ammonites with a hood, since a supposed fossil hood turned out to just be a shell fragment (Lehmann et al. 2015), today's neocephalopods lack a hood, and being able to retreat deep into the shell may have made one unnecessary (Monks & Young 1998).🧵6/7

New research from Stephanie Drumheller-Horton, Robin O'Keefe, and Christopher Brochu: a Polycotylus cervical vertebra with a Xiphactinus tooth embedded in it!

@WitmerLab @CurrentBiology @AMNH @SteveBrusatte It's such a good book!

9.5 m #Sarcosuchus lived with small terrestrial crocs, huge #spinosaurids, sailbacked #Ouranosaurus, & wide-mouthed #Nigersaurus when the Sahara was lush and tropical in the Early Cretaceous. Paul Sereno transformed our understanding of these creatures. #FossilFriday #Croctober

Amazing opportunity for any recent PhDs interested in Mesozoic marine reptiles.

Hey, our little polycotylid #Unktaheela has made it into a new card game! They've got a kickstarter launching soon--looks fun!

Unktaheela is a very small plesiosaur. Here's the wiki, it's a neat little creature: https://t.co/ZtPIwdtjuQ
Side note, the lore snippets are my favorite part of the cards we've made, and this one might be my favorite.

It's been a wild 4 weeks since our #Traskasaura publication: covered by ~900 outlets, 2nd-highest Journal of Systematic Palaeontology impact score in the last 3 years, & 10th-highest ever! (Infographic ~2 weeks old) #MarshallUScience #paleontology #FossilFriday
