No sand dollars in the Mesozoic.

Fine tuning lower Cedar Mt. Fm. X-section by correlating marker levels and pulling out the Crystal Geyser section (lower Yellow Cat Mbr. only 2 m thick), & use the data to show the distribution of Ankylosaurs in the northern Paradox Basin vs the Yellow Cat master section. CONTEXT IS EVERYTHING!

Shoved the Iron Stone Anky section east of Utahraptor Ridge and the Doellings Bowl section into my X-section of rhe lower Cedar Mt. in eastern Utah. The cervical spine @jlivelypaleo.bsky.social found compares well with that of the new Anky from DB & is from same level at top of histosol interval.

This might be a first in the world of #paleoart

Dinosaur skeletons are selling for millions. Is science missing out? | CNN The sale of a Triceratops fossil for $5.55 million is the latest in a list of dinosaur specimens fetching colossal fees in commercial sales. What does that mean for researchers and museums?

Another day, another dinosaur auction.

This time, I share my thoughts with @cnn.com , on commercial fossil collecting, the tragedy of dinosaurs disappearing from public display and education, but in the end, even some optimism!

Photograph of a cast of the holotype skull of Panoplosaurus mirus (CMN 2759) in the foreground, with some other ankylosaurs lurking in the background (Gastonia, Ankylosaurus, Pawpawsaurus).

CT-scan-based volume renders of the Panoplosaurus mirus holotype skull (CMN 2759) (top), a referred specimen of P. mirus ROM 1215 (middle), and a referred skull of Edmontonia rugosidens AMNH 5381 along with a slice through the snout (bottom).

Photos from a May 2025 post (while finalizing details for the Livius et al. manuscript) focusing on the Edmontonia rugosidens holotype (USNM 11868). At top right is Witmer studying the old-fashioned x-ray film-based versions of the 1998 CT scan we made of the skull. The middle photo shows lateral views of the skull, and the bottom photo shows stereoscopic photos of the ventral surface of the skull.

#FossilFriday From the depths of the pandemic to a wonderful #OA article out this week in @societyofvertpaleo.bsky.social—https://bit.ly/48oGPZG—congratulation to Marissa Livius, Jordan Mallon, & the whole team! A blast to dig back into ankylosaurs to sort out the Panoplosaurus-Edmontonia mess.

Fun visit last week to the American Museum of Natural History! Such impressive displays of giant fossil turtles, dinos, and more.

I said this yesterday but today we get Ptychotherates bucculentus, a new Herrerasaurian from GRCQ, and a formal name Morphoraptota for the North American Herrerasaurian Clade! Ghost Ranch Coelophysis Quarry is so much more than just Coelophysis!

Here are the cervical rings and shoulder spine as preserved. just add the overlying keratinatius horn. @utahpaleo-ufop.bsky.social @paleontologizing.bsky.social

Any good photos of the dentition from LACM 5572 ?

Drop Ethan an email at ecowgill@utah.gov. He also has sturgeons, and a large disarticulated skull of the amioid Melvius. We have to get this wunderkin into a Ph.D. program. He is looking to get in a program in Britain.

Early Cretaceous dinosaur tracks in Mongolia. www.asahi.com/ajw/articles... Pictures from story. Less diverse, but similar to Mill Canyon tracksite no. of Moab in Utah. @utahpaleo-ufop.bsky.social @andrewtracks.bsky.social @ichnologist.bsky.social @societyofvertpaleo.bsky.social

The Pokémon universe goes hard on ecology and climate science The Pokémon franchise, including its recent game Pokémon Pokopia, is inspired by real animals and their ecology. It’s no surprise that so many scientists love to try and “catch ’em all”

My latest for @sciam.bsky.social is all about the real biology, ecology, and climate science that is used to create the world of Pokémon, and how scientists use it to teach science in the real world.

This is just about the most fun I’ve ever had interviewing anyone, and I hope you enjoy! 🧪🌎

#MosasaurMonday! How about this impressive Tylosaurus proriger snout from the basal Mooreville Chalk of Ala.? Collected in 1983 by a crew from the late, great Red Mtn. Museum, it's part of a fairly complete skeleton measuring 40+ft (12m). In the collections of @mcwanescience.bsky.social!

Did you know that while Allosaurus and Apatosaurus explored eachother's bodies in the Morrison Formation, small, bipedal, omnivorous crocodylomorphs with spoon-like jaws were running around on the forest's floor?

Happy #FossilFriday meet Kaprosuchus saharicus! Nicknamed the “Boar croc” Kaprosuchus lived during the late Cretaceous of Niger 🇳🇪 roughly 95 million years ago. Kaprosuchus is a member of the Mahajangasuchidae an early branch of notosuchian crocodiles

Shoulder spines did not curl up; straight and relatively long.
