Three very delicate bones cleaned in the past 2 days. SUPER RARE - 2 limb bones from a parrot-mimic oviraptorosaur, and the other is a neck bone from a flying pterosaur.

CLUMSY MALE DINOSAURS INJURED FEMALES DURING MATING: Our new paper (Filippo Bertozzo et al. 2025), shows that a common tail injury seen in duckbilled dinosaurs was probably caused by heavy male dinosaurs clumsily crushing the spines of females during mating.

BABY DUCKBILL #dinosaur: Deanna just finished prepping this cute femur. We have a couple of nice jaws from a similarly-sized baby hadro from this same site, so maybe they are part of the same skeleton.

It's cold at our digsite today, but we just found this delightful troodontid raptor tooth. This is the site where we have found parts of a troodontid skeleton. Maybe a jaw is nearby, waiting to be found next!

This partial hand does not look like the troodontid from "Jack's bonebed", so we think it is from a parrot-mimic oviraptorid. We have a few tentative pieces of the skeleton so far, but it's looking really promising!

We're going to debut this fantastic skull reconstruction of Daspletosaurus wilsoni at Badlands Dinosaur Museum's "Expansion Unveiling" event, April 26th!
Here, DSU student Wes Isaac measures the skull so he can make a welded metal armature for display.

It's permit season! Since 2015, Badlands Dinosaur Museum field crews have found 238 new fossil sites in the Hell Creek & Judith River Formations, all but 9 on public lands. The biggest fieldwork program in our region. So proud of all our field crews! #fossilfriday #dinosaurs

Super cool. Super rare. This is a braincase from a raptor dinosaur: probably the troodontid that we have been collecting (we have the frontal, and many other bones). Deanna finished cleaning this yesterday! From US public lands administered by @BLM_MTDKs #dinosaur #fossilfriday #fossils #museumlife

My office right now. I wanted to do a #FossilFriday post with Deanna's current prep project, but it's not finished yet (watch this space).
In the meantime... this is gonna be a special piece for our exhibit.

I really like paleontology-themed additions to buildings etc. I collect the images for future reference. Maybe in my old age I'll start metalworking and making door handles, weather vanes, gargoyles, fences... even bike racks that are paleo themed.

Got these for kids activities in the museum. Last set I bought were stolen in the mail, been waiting years for another set to come up for sale!
Seriously, Jurassic World has dreadful toys of made up dinosaurs. Ironically they haven't made a Dakotaraptor yet!
