In honor of Hans Dieter Sues a #FossilFriday, the big Kayentatherium that Hans built much of his dissertation around. Got to help excavate in July 1981 working for Farrish Jenkins and first met Hans, while he was working on the specimen at Harvard a few years later. @paleontologizing.bsky.social

Loren Babcock from Ohio State's Orton Geological Museum (at left) gave a great seminar today on Thomas Jefferson, Megalonyx & paleo history to the @ohiouniversity.bsky.social Earth & Environmental Geosciences Department. We closed the day by bringing everyone to our lab for a fun tour! #FossilFriday

Cropping teeth of Utah's new Kayenta ornithischian, so for #FossilFriday Scutellosaurus lawleri. My pics of the original exhibit & gastondesign.com mount. Not the transition at base of tail from 2 rows of osteoderms across midline to 1 medial row running down the tail. @utahpaleo-ufop.bsky.social

A primer grey mosasaur noggin upside down in my workspace, as I'm trying to fit and detail all of the subassemblies for replication
Happy #FossilFriday in flashback form!
This is the master copy of Wally, the best Mosasaurus found in western Kansas to date. The skull is about 1.2m (4 feet) long and when upside down like this, you can really see those nasty teeth on the palate.
As if all the other teeth weren't bad enough 🧪
I’m excited to share a new project that I hope will be a valuable resource for the paleo community!
I'm working on a textbook about plesiosaurs and compiled a comprehensive overview of all currently valid plesiosaur taxa and some nomina dubia. 1/3

#FossilFriday A beautiful Cretaceous seastar. This fully articulated specimen of Calliderma was collected in the Chalk of England.

black and white engraving. Workmen handle the Mosasaurus skull in dramatic poses, while one holds a torch, lighting the scene and the quarry wall behind. Two robes men in fancier clothes and hats seem to be directing the proceedings
Happy #fossilfriday from this likely over-romanticised 1799 engraving of the discovery of the Mosasaurus hoffmannii holotype in a chalk quarry near Maastricht
This is on display at the National Museum of Natural History in Paris, after being looted during the French Revolutionary Wars
Photo of Dr. Hans-Dieter Sues and Tim Fedak, photograph of Teraterpeton skull, skull of Hypsognathus, and Clevosaurus, all from Nova Scotia.
I was deeply saddened to hear of the recent passing of Dr. Hans-Dieter Sues. He has generously supported my work over the past thirty years and he made huge contributions to paleontology here in #NovaScotia. From 2021, a @novascotiamuseum.bsky.social showcase video youtu.be/AjzIuaQ-Qn0 - RIP Hans.

The fossils of adults and juveniles of this hadrosaur reveal how its bones changed as it grew. #Paleontology
