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. From US Public Lands administered by the Bureau of Land Management

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. /1

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. Dinosaur Park Fm, Montana. ~76M years old, Late Cretaceous #fossilfriday

Microbiology lecturer JOB: Dickinson State Uni. MSc required. $55-60k pa. If you're a paleontologist who can teach microbio, you can do the job! Badlands Dinosaur Museum (my institution) works with DSU paleontologists & students on a variety of projects. Join us! prd.hcm.ndus.edu/psc/recruit/...

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.

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! Dino. Park Fm, Montana. From US public lands #FossilFriday #dinosaur

Loving this 3D print of Champsosaurus. Model freely provided with Dudgeon et al. 2024. #FossilFriday #fossils

Possibly the best #dinosaur rubber stamp I own (I have about 100). #FossilFriday

I just liked the shape aesthetic. #dinosaur factory photos: Daspletosaurus wilsoni holotype. #fossilfriday

International collaborative research just published! Michailow et al (2025). Link in comms (free) Photo: some nice teeth in our collection (left to right): tyrannosaur; duckbill hadrosaur; (top) crocodile; (bottom) raptor; tyrannosaur with wear mark #fossilfriday #dinosaurs

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! #FossilFriday #dinosaur #dinosaurs #oviraptor #science #NorthDakota

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. #dinosaurs #fossilfriday

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

Steve just finished cleaning this tiny mammal jaw which we collected in 2024! Check out those tiny teeth! From US Public Lands administered by the Bureau of Land Management. Found by Jason French, July 2024. #fossils #mammals #dinosaur #FossilFriday #publiclands

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. #dinosaur #dinosaurs #museum #museumlife #fossil #scicomm #tyrannosaur

MUSEUM EXPANSION: I've whispered in a few places about this. Now our board has put together an official unveiling evening to share our plans over dinner with community stakeholders. See what we're going to build & how you can be part of it! #fossilfriday #dinosaurs #scicomm

Something BIG is coming

If you'd like to see the 1st & 2nd Paleontologizing livestreams from this week, they're now archived and available. Monday we mostly take a tour of the exhibit; Tuesday we toured the lab and collections, discussing some of our important discoveries from the past few years. #Fossilfriday #dinosaurs

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.

Danny Anduza's Paleontologizing is just starting the 2nd day of livestreaming here at Badlands Dinosaur Museum. Today we'll be more behind the scenes looking at collections and the lab: #dinosaurs #fossilfriday #fossils #scicomm www.twitch.tv/paleontologi...

Leaked photo from Hollywood. :P 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!

JOB: SEASONAL PALEONTOLOGIST BADLANDS DINOSAUR MUSEUM 15wks, starting in mid-late May or early June 2025 (flexible). $19.07 / hr. Must be legally able to work in US. Applications close Feb 10th 2025. Come work with us! www.governmentjobs.com/careers/dick... See listing & comments for details

Our museum has an online shop now! Here you can directly buy some of our exclusive merch. There's a few items there right now, with many more to come! shop.dickinsonmuseumcenter.com/collections/...

Saurolophine duckbill upper jaw from the middle Dinosaur Park Fm, Montana. I hope the rest of the skull is nearby! Just cleaned by Steve in our lab at Badlands #Dinosaur Museum. #FossilFriday. From US public lands (BLM).

A different narrative on fossil sales, by Andrew Rossi. Good investigative journalism into the completeness, scientific accuracy & value of the Allosaurus & Stegosaurus that sold in London this week, with implications for fossil auctions in general cowboystatedaily.com/2024/12/14/w...

Latest #pterosaur wing bone, super rare! So well preserved! Currently being prepped at Badlands Dinosaur Museum by Deanna. Middle #Dinosaur Park Fm, Montana. From US public lands administered by the Bureau of Land Management. #FossilFriday #scicomm

In the lab here at Badlands Dinosaur Museum, Steve is busy detailing the teeth on this large hadrosaurine c.f. Prosaurolophus upper jaw. Middle Dinosaur Park Formation, Montana. Collected 2023, US public lands administered by the BLM #dinosaurs #fossilfriday #scicomm

We just got this fantastic Wild-Heerbrugg training microscope in the lab at Badlands Dinosaur Museum. Great for new volunteers to learn how to prep fossils! Very good value on eBay for $1200.

New collaboration out today (Free access). For me, Taia's new toothmark classifications will make it easier to parse out feeding behaviors. I had done some similar (much less extensive) revisions in our Trike-bitemarks work. More to come! t.co/z14NKE0j8X

If you didn't see our live 8th ANNUAL FIELD REPORT last night, you can now stream it in 1080p on YouTube! www.youtube.com/watch?v=0350... Fossils collected under permit on US public lands (Bur. of Land Management & Bur. of Reclamation) #FossilFriday #dinosaur #dinosaurs #fossils #scicomm

Please join our paleontology team for Badlands Dinosaur Museum's 8th ANNUAL FIELD REPORT where we will present some of our exciting new discoveries! Thurs 5th Dec, 6pm MST (5pm PT/ 8pm ET). (Link in 1st comment) #dinosaur #dinosaurs #FossilFriday #LiveFromTheField #scicomm

A NEW WING BONE from our PTEROSAUR, & limb bone from a baby lambeosaurine duckbill. We'll be talking about these & more new discoveries in our 8th Annual Field Report, livestreaming free on Dec 5th. #Dinosaur Park Fm, Montana. From US public lands (BLM). #FossilFriday

Classic paleoart, from a 1937 postcard. I collect images of theropods getting beaten up by ornithischians. #dinosaurs

I don't remember where I got this from, but apparently it is by Peter Klucik (Czech artist b. 1953). Iguanodon is the best #dinosaur Happy #FossilFriday!

Two days ago our #Stegosaurus came back from Colorado. Over the summer, Chris Madsen mounted the skeleton cast that had lain in our central sandpit for 30 years! This is part of extensive renovations that will be taking place over the next year or so. Photo: Amanda. #dinosaurs

A c.f. Brachylophosaurus (duckbilled #dinosaur) jaw from our bonebed site (400+ bones and counting; 5+ individuals). A mass death assemblage where #tyrannosaurs feasted on a mixed-age herd of brachys. US Public lands (BLM); Judith River, Montana; ~76Ma (a BlueSky exclusive to get my profile started)

(My first post) A hadrosaur arm bone absolutely covered in toothmarks made by a carnivorous #dinosaur, probably a #tyrannosaur, although there have been suggestions that these small marks might be from #raptors. US public lands (BLM); Judith River Fm, Montana; ~76Ma, Cretaceous. #fossilfriday
