Our paper on turtle origins is finally out in Current Biology, with two major implications for our understanding of reptile evolution 🐢 #Paleontology #Turtles #Evolution www.cell.com/current-biol...
A pair of Eunotosaurus by Gabriel Ugueto: a sense of scale is provided by Glossopterus leaves in the fore-and-background and by a prosbolid hemipteran insect Phylogeny of major reptile groups, showing turtles (Pantestudines) as early archosauromorphs and the putative stem-turtle Eunotosaurus as a millerettid stem reptile

Attention Science Communicators! We are conducting a survey on the landscape of science communication & need your help gathering experiences. Please send this to #SciComm ppl you know. We want to get as thorough a sense of the state of the field as we can. umiami.qualtrics.com/jfe/form/SV_...
A block of text that says "Scientists at the University of Miami are carrying out a research study on trends in the field of science communication. 

For this survey we are defining science communication as work that is done: 

• by a technical subject area expert in some field related to science, technology, engineering, or mathematics, 
• outside of classroom settings 
• aimed at the public 

If you are 18 years of age or older and work or recently worked in this field (full-time, part-time, or as a side project), please click the link below to complete a short survey. If you are interested in learning more about this research study, please e-mail us at Julia.wester@miami.edu. In the body of your email please provide your full name, and if you would prefer to be contacted by phone, your phone number and the best time to reach you. Contacting us for more information does not commit you to participating, and should you decide to participate you may terminate your participation at any time."

I've heard there's a meeting for @societyofvertpaleo.bsky.social tomorrow. Hopefully they're planning on responding to this in more earnest than their email this morning.

3 hours ago, I shared my results of having combed through ~470 DOJ Epstein files that mention Jack Horner, his MSU email, or "Dinochicken". I posted a copy, w/ screenshots and receipts, to r/Paleontology. It has been pinned by moderators and thus far viewed 38k times. www.reddit.com/r/Paleontolo...

Jack Horner in the Epstein File trying to raise money to fund dinosaur research. When I discovered we had rich nazis on our dig in 2008, I dropped them like a rancid turd; ask Don. There will never be a Trumpasaurus with my name attached! @paleontologizing.bsky.social @utahpaleo-ufop.bsky.social

I have to assume Mr. Xkcd was subject to massive tectonic forces which overturned the beds.

Incredible example of how AI is destroying Google search: working on a paper on mollusk shell assemblages in Panama so I tried to search for the classic paper on the left (which I know about because I was a field assistant). Instead Google AI hallucinated a completely fictional architectural firm.
An image of a classic paper by taphonomists Mairi Best and Susan KidwellAn image of a Google AI description of a completely fictional (as far as I can tell) architectural firm named "Best & Kidwell" that is supposedly based in Panama City. It even includes a picture of one of the partners(?).

Reading, however slowly you do it, is thinking. And you cannot do research if you do not think. Undergrads, I can understand. But if a grad student uses LLMs to summarize papers, just leave, go and give the funding and space to someone who actually wants to learn something.

Whoa, you mean the people who had serious questions about this were right to question them the entire time, and just saying "trust me bro" isn't a good response to criticism.

Never thought I'd compliment Ohio, but at least the Cincinnati airport had a nice little "welcome to Cincinnati" sign in the airport for all the paleontologists.

Getting covid and then bronchitis just before the SVP meeting sucks, in part because I had to slow down poster design, and now I'm paying extra to get them in time.

I said it on the cursed site, but he didn't even tell me he was taking a photo! I guess I was actively showing people fossils though, which is one of my favorite things to do!
