Sad that I have such high expectations relative to Dino documentaries. Any one want to focus on an entire dinosaur series spanning the entire Mesozoic centered on the the most complete record on the planet surrounding or National Parks on the Colorado Plateau, call me.

Into second episode, certainly some fine animation, but the Science is being being played way to fast and loose for my taste. These things need a diverse advisory board like Discovery Channel did for When Dinosaurs Roamed North America.

OK for #FossilFriday, who has been watching Netflix' The Dinosaurs? Who were the consultants on this..I am just 20 minutes in and not to impressed so far. I have to admit I'm pretty fussy. PERHAPS,...I know to much and have to many opinions. @utahpaleo-ufop.bsky.social @paleontologizing.bsky.social

A scanning electron micrograph shows the planktic foraminifer Parvularugoglobigerina eugubina. Its appearance about 6,400 years after the Chicxulub impact defines the upper boundary of the first planktic foraminiferal biozone following the K/Pg mass extinction.

New species evolved within a few thousand years of the Chicxulub Impact 🧪

The immediate aftermath of the K/Pg mass extinction (ca. 66 Ma) in the marine realm was characterized by the initial recovery of productivity and the originations of new species.

Assuming a 30-min commute to/from train station, 45-min to/from airport, 30-min early arrival for train and 90-min for plane, 500 mph plane (LAX-JFK is ~450), a 280 mph train is faster than flying any distance less than 950 miles.

Here is a 950-mile radius circle centered on Kansas City.

Maybe it’s a bad idea to put people in charge of government who are eager for the rapture.

It’s morning of day 1 of my shark field research skills class! Wish us luck, and let me know if you want to sign up for the fall! 🦑🧪🌎🦈

Meet three scientists who said no to Epstein The warning signs included a web search, a mother’s doubts, and inklings of a “sexist attitude”

Many of the scientists Jeffrey Epstein courted were already well-established and well-funded. So why didn’t they all just say no? Science talked with three who did just that.

Here’s how Epstein approached them, and why they refused to have anything to do with him. ⬇️ https://scim.ag/40qbXnv

WELL, DORKS! @timothysnyder.bsky.social says there is nothing more important than science and no one more important than scientists to establish a decent society and politics...which is why we are STANDING UP FOR SCIENCE on MARCH 7TH across the nation!

Total lunar eclipse from 4-5 AM this morning. www.timeanddate.com/eclipse/in/u...

When I taught at the University of Nebraska, I fought with the National Arbor Day Foundation about planting all are good roadcuts!

"Due North: Exploring Alberta's Northern Dinosaur Ecosystem, University of Alberta Palaeontological Society, Wednesday, March 4 5 - 7pm, ESB 1-39, University of Alberta." The background is a hadrosaur footprint from around Grande Prairie.

"Do Pre-Existing Conditions Prime the Earth for Mass Extinctions? Wednesday, March 5, Royal Tyrrell Museum Speaker Series 2026, Royal Tyrrell Museum of Palaeontology, RTMP auditorium (and zoom)" The background is an image of the badlands in southern Alberta along with a cut into the sides, revealing the K-Pg extinction layer.

"Presentation Dino Dentist, Wednesday, March 5, 3 - 3:30pm, Royal Alberta Museum, Edmonton" The background is a closeup of the skeletal skull of a gorgosaurus

Looking forward to Utah Paleontological License Plates supporting paleo research in Utah. mail.google.com/mail/u/0/#in...

🧪🏺 Update - authors have new paper showing how useless gen- #AI is for archaeological illustration.
All 400 images were multiply inaccurate (physically, socially, technologically, environmentally), even with improved prompts.

In honor of Hans Dieter Sues a #FossilFriday, the big Kayentatherium that Hans built much of his dissertation around. Got to help excavate in July 1981 working for Farrish Jenkins and first met Hans, while he was working on the specimen at Harvard a few years later. @paleontologizing.bsky.social

Cropping teeth of Utah's new Kayenta ornithischian, so for #FossilFriday Scutellosaurus lawleri. My pics of the original exhibit & gastondesign.com mount. Not the transition at base of tail from 2 rows of osteoderms across midline to 1 medial row running down the tail. @utahpaleo-ufop.bsky.social

That is the Southern Parkway connecting I-15 south of St George, Utah via a loop east of the city to the main road to Zion National Park. That entire region is being developed on top of a vast paleontology site dominated by tracksites & extensive archaeological sites by Virgin & Santa Clara Rivers.

#FossilFriday A beautiful Cretaceous seastar. This fully articulated specimen of Calliderma was collected in the Chalk of England.

Plesiosauria: A Systematic and Taxonomic Overview Comprehensive systematic and taxonomic overview of Plesiosauria, including valid taxa and nomina dubia based on recent data, with detailed taxon listings.

I’m excited to share a new project that I hope will be a valuable resource for the paleo community!

I'm working on a textbook about plesiosaurs and compiled a comprehensive overview of all currently valid plesiosaur taxa and some nomina dubia. 1/3

Paleo mitigation is important! The yellow star marks the most import Kayenta fossil site in Utah, plants, tracks, fish (whole and partial) abundant and diverse teeth (diverse dinos & crocs, pterosaurs). Sadly, the site is under a new highway & hill is gone forever. @utahpaleo-ufop.bsky.social

Well for anyone that thinks mitigation is not important in paleontology. The yellow star marks the most import Kayenta fossil site in Utah, plants, tracks, fish (whole and partial) abundant and diverse teeth (diverse dinos & crocs, pterosaurs) We are documenting the 4th ornithischian in the E. Jur.

Reporting 2 verts from Quarry 9 as alverezsaurid is a big deal, but I would strongly suggest that Quarry 9 is Kimmeringian in age and not latest Tithonian. Bet older than 150... Still very cool Pete, very cool! Cope's Nipple on west side of Denver Basin is Tithonian, I bet, but anything in Wyoming??

Utah teen vying for 'America's Most Artistic Kid' A Bountiful High School student is vying to win "America's Most Artistic Kid," a contest created by the well-known artist Bob Ross.

One of our younger members of Utah Friends of Paleontology kicking some butt with his artistic skills. cdn.jwplayer.com/previews/dE3... Nice to see! @utahpaleo-ufop.bsky.social @thestemvillage.bsky.social

Still looking for a preCloverly (Aptian or older, <118 Ma) ceratopsian. I'm thinking that the terminal Jurassic Morrison megafaunal extinction opened up some ecological niches.

We plan to attend SVP'S town meeting today! Mentor, not molester! @societyofvertpaleo.bsky.social @utahpaleo-ufop.bsky.social
