Photo of me alongside specimen, on display at DMNS

Closer-up photo of "Teen Rex" specimen, showing the juvenile Tyrannosaurus skull (only about 2/3 of a meter long!) with a ridiculously beautiful fossil palm frond stretched out just beyond the open jaws

I got to see the incredible "Teen Rex" in Denver a few #FossilFriday s ago

Not only will this juvenile specimen be *hugely* helpful in understanding the growth of Tyrannosaurus, but that *gorgeous* palm frond might offer insight into which conditions could fossilize plants and bones side-by-side

What does somebody's favorite dinosaur say about them? We're chatting about a new YouGov poll which asked that question of Americans. It's dinosaurs, pop culture, & public understanding of paleontology all intersecting on today's stream —

The advantage of starting off with a speciose clade is that it's got a lot of species.

The disadvantage of starting off with a speciose clade... is that it's got a lot of species

Judging by what I observe from my colleagues, the consensus answer might be 'include a photo of yourself doing fieldwork, but make sure it's at least a couple decades old'

We need @paleontologizing.bsky.social on this, cause how can there be people without a favorite dinosaur?

Thanks so much! This is interesting (and I would argue, important) work.

If it's not too much trouble, I'd be very grateful for some full-sized chart PNGs sent to paleontologizing [at} gmail dot com so that I can dive into this on my broadcast this afternoon

Well I know what we'll be talking about on today's livestream...

For paleontologists, the idea of 'personal favorite dinosaurs' can be a nice "finger in the wind" test measuring the general public's level of engagement with fossil science

Should be a fun discussion! www.twitch.tv/paleontologi...

There's a TON of #paleontology and natural history news to cover today, from even-weirder-than-we-thought Muttaburrasaurus to new a new herrerasaur from New Mexico on the extinct side, and even recovering monarch butterflies on the still-living side of things

Feel free to join us and hang out 🦕

Aww hell yeah this is why I am on social media, to experience awe like this.

Diagram, from Wikipedia, highlighting in red the clavicles on a human skeleton

It seems that clavicles are in the news again today (?) so here's a couple clavicle facts:

- In the humans, the clavicles ("collarbones") are reportedly the most frequently-fractured bones in the body

- In theropod dinosaurs (including birds!), the clavicles fused to form the furcula or "wishbone"

Twitch screenshot of me in my office. The GIGANTIC life-sized Diplomoceras heteromorph ammonite is on the wall behind me as a 3D print, as well as a huge Archelon rear flipper and a brand-new trionychid turtle, too

It's a chill #TurtleTuesday here on the stream, and we're talking all about the evolution of turtles (while frequently getting distracted by viewer questions and all kinds of tangents about the history of life on Earth).

Feel free to pop in and say 'hi' in the chat @ twitch.tv/paleontologizing

Twitch screenshot of me in my office, with SCADS of (mostly gynosperm) plants on the office wall behind me. Ferns, palms, cycads, ginkgos, and magnolias peek out from around and in between framed illustrations of various Mesozoic-looking plants

We're celebrating the fossil history of plants for #PlantAppreciationDay today. Cycads, horsetails, ferns, and bennettitales are sure to feature prominently as we discuss Mesozoic floras and otherwise strive to 'give the plants their flowers' 🙃

JPI was a *huge* part of my childhood

I would beg my parents' permission to log on and print out entries from the "Dinopedia," which I put into a big binder — and then I'd reorganize the genera on a semi-weekly basis according to different phylogenies I saw in library books.

Stealing a Nation - How the UK/US Stole the Diego Garcia Island YouTube video by Renegade History

Despicable and shameful, but not surprising. There's a well-made documentary about the largest island's history if you want to get really angry

NASA's comms team is a reminder of the value of science communications.

It's not just the mission, but how the science is made visible & shared openly through multimedia

Without storytelling, even the most extraordinary achievements wouldn't get the attention they deserve

If you’ve been moved & inspired by Artemis, NASA needs your help. Literally during A2, the president proposed cutting NASA science 47%, canceling 54 missions, including many already in-flight. To help stop these cuts, check out @planetarysociety.bsky.social www.planetary.org/save-nasa-sc...

Agreed! The piece you were interviewed for a couple years ago was much more thoughtful and comprehensive

Earnest answer: In the museum field, we use dermestid beetles to remove flesh and get clean skeletons

Field photos of the tracks as excavated and during the jacketing process

Happy #FossilFriday from some of my favorite dinosaur tracks from the Hell Creek Fm. These ironstone oviraptor or tyrannosaur tracks were found by Mike Triebold in the early 1990s and named Wakinyantanka by Lockley and Hunt. 🧪🦖
