A nice addition to our exhibit. This Ornithomimus skull was painted by one of our volunteers, Ty Patterson. #dinosaurs #fossils #fossilfriday #museums

The house sparrows in Bozeman did that to our old rental.

A rare portrait of me with the snout of a hell pig (entelodont). Kindly donated to our museum this year by Betty Leppart, from the Gary Leppart collection. In the new year I will be 3D printing a back part of the skull, and getting this on exhibit. #FossilFriday

Daspletosaurus wilsoni holotype skull full-size reconstruction. Went on display in our exhibit hall (Badlands Dinosaur Museum) Sept 2025. The nicest Daspletosaurus skull reconstruction I think. Casts possibly available in 2026. #dinosaurs #fossils #fossilfriday

Postcard sets are up now too. I really wanted a big range of exclusive merch available for this christmas. We've got a few out there, but we've got lots of cool new ideas in the pipeline, based on specimens and artwork we commissioned.

I made a lot (I run them off on our printer when it's not making exhibits). The detail is really nice -you could probably code characters from these! (I am unreasonably pleased with how well they came out). We're planning on more exclusive merch like this.

NEW MAGNETS: Our shop now stocks magnets of Liberty the Lambeosaurus, & Daspletosaurus wilsoni, all in glorious shades of gold, silver & copper (only US$12 each!). Lambeo based on 3D scan of our skull (the only USA specimen); Dasp by Andrey Atuchin. Link in comments #dinosaurs #fossilfriday

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.

This new finding adds to our understanding of dinosaur behavior. Although it might seem unintuitive, these battling dinosaurs being injured during reproduction is in keeping with what we see in modern day animals. (art: Troco) /10

A key implication is that these injuries should only be sustained by females, so this might be a way to infer the sex of dinosaurs. The inability to infer males & females in dinosaurs has frustrated scientists since study began nearly 200 years ago! (art: Troco) /9

The new study combines detailed descriptions of the injured specimens with Finite Element Analysis (FEA) which computer-models how a structure reacts under stress. This showed that the injuries caused to the tail spines were consistent with a force delivered from above. /7

A more recently collected Dickinson specimen, "Had Enough", is another of the nine key skeletons in the study. (specimen found by volunteers Stephanie and Samantha Sutton) /6

Here Filippo and Liz look at one of the key skeletons, "Warwick's Duck": on loan at Badlands Dinosaur Museum from Museum of the Rockies for a number of years, and can be seen in the exhibit (found by Warwick Fowler, in 2009). /5

Duckbill researchers have noticed for many years that there were often injuries to the long spines of the tail vertebrae. The tips of the spines were broken, but had healed (albeit usually twisted and deformed) showing that dinosaur survived the incident. /2
November 4, 2025 at 8:36 PM
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.

Hadrosaurine braincase. #fossilfriday. Collected by Badlands #Dinosaur Museum, Jul 2025 & cleaned by Deanna. Associated skeleton from BLM-administered US #publiclands. Dinosaur Park Formation, Montana.

You're looking up into the underside of the skull roof. The bottom of the photo is the frontals.

A pubis (pelvic bone) from a medium sized ceratopsid. I'm going to be plaster jacketing this in a few minutes. Dinosaur Park Fm, Montana. From US public lands administered by the Bureau of Land Management.

A selection of teeth collected today in the Judith River. Top row are all raptors, including a cool Dromaeosaurus with a wear facet. Bottom left are nodosaur, bott right is a tyranno.

A nice theropod claw found today. #dinosaurs #fossilfriday from US public lands BLM. Judith River FM.
June 25, 2025 at 3:17 AM
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!
