@ruckusinmyhead @NatSciChannel @ARGAtheropodfan The BOTM figure is based on Chasmosaurus belli, which is the type species of the genus, and still valid.

@NatSciChannel @ARGAtheropodfan So where does that leave the botm figure?

🚨NEW STUDY DROP🚨 Chasmosaurus russelli is no more! The species has been assigned to a new genus, Cryptarcus! They found the features that were used to put it in the chasmo genus were not strong enough to keep it there. 🎨: Tuomas Koivurinne

Specimen (Archaeotherium sp.) from the historical League collection. Originally found in South Dakota White River Group, 32 million years old. Plus a reminder photo of how MASSIVE the Leppart skull is (AND it's from North Dakota)

Today, Amanda is 3D scanning our Hell Pig (Entelondont) skull (usually in the lobby display). We're going to use the 3D scan to restore the enormous snout kindly donated 2025 by the Leppart family. Here UV light shows the skull is ~60% real. #FossilFriday #fossils #scicomm

BABY DUCKBILL: Steve just finished cleaning this super cute jaw, with rows of tiny teeth! This matches another jaw, femur, and vertebrae that we collected from the same site. A baby dino skeleton is coming out! #fossilfriday #dinosaurs #dinosaur #scicomm #fossils #publiclands

SITE: "Jack's Bonebed", Dinosaur Park Formation, ~76 Million Years old, Montana. Site found by Jack Wilson on US Public Lands administered by the @BLM_MTDKs. Permanently reposited at Badlands Dinosaur Museum, Dickinson, North Dakota.

@Brontops_ @Paleojim There's a more or less complete skeleton at MOR: Flora HM, Wilson JP, Gardner JD, & Fowler DW (2015) A three-dimensionally articulated probable oviraptorosaur from the Hell Creek Formation of Montana. JVP 34(5, abstracts vol): 124. It has preparation challenges.

Picture posted by @Paleojim on Fb. Although it appears fragmentary, it is among the most complete caenagnathids found so far in North America.

@Sketchy_raptor but, the detail and quality of the sculpting is superb.

@Sketchy_raptor friendly suggestion: most theropod toes aren't symmetrical about D-III axis. This is mistake based on comparison with extant emu. D-II ungual should be largest & most hooked. D-II & D-III should be sub parallel with D-IV slightly splayed. D-IV ungual is more hoof like in tyannos.

Stupid tyrannosaurs in a million bits. This is the left side of the snout of Holger, a Daspletosaurus c.f. wilsoni. The skull of Holger, our 2nd completed Dasp site, is currently being restored. From US Public Lands administered by the BLM; Judith River Fm, Montana. #dinosaurs

Navajoceratops! really nice!

NOTE: The lab experience is not available for 2026 because we're building the new lab, but I am hoping I can pull together the funds for 2027. I am very hopeful we might be able to get university dorm rooms for accommodation too. TRYING to make paleo accessible for all.

ALSO: Would you be interested in a lab volunteer experience? I'm thinking of applying for funding for a person to run our (new, BIG) lab in the summer so we could have ~5 volunteers prepping dino bones. Not everyone can do fieldwork, so this would make paleo available to more ppl

VOLUNTEER ON A DINOSAUR DIG: We run one of the only free dinosaur digs in the USA. We work public land and the fossils go in our public museum, forever. It's hard work, but we find some cool things. If this sounds like you, we're taking applications. Link in comms. #dinosaurs

If you're a TV crew looking to film a dinosaur dig in summer 2026, we have multiple raptors, possibly more than one pterosaur, duckbills, and all kinds of cool things just at our main site. It also involves no hiking, you can park on top of the site. Crazy eh?

CANNIBALISM OF AN ADULT TYRANNOSAUR BY A JUVENILE: Our new study on a Badlands Dinosaur Museum fossil reveals dinosaur cannibalism where a juvenile tyrannosaur feasted on the carcass of a dead adult! 3D reconstructions supervision Yu Xin, designer Shen Li, sculptor Liang Junwei

Link to our press page: dickinsongov.com/museum-center/…

The specimen (BDM 124) was discovered in 2012 by fossil collectors Brent and Rod Olson on private land in Montana which contains exposures of the Judith River Formation. In 2023, it was donated to the public repository at Badlands Dinosaur Museum, Dickinson ND.
