Utah Friends of Paleontology will have Colin Boisvert as speaker on Thursday November 13th, 7:00 pm Mountain Time. He will be speaking on his research on Diplodocid sauropods, while at BYU. The link for that talk is here. meet.google.com/piy-hxai-qog @utahpaleo-ufop.bsky.social

Out looking at correlation of Lower Cret strata and looking at the J-K boundary with Ed Simpson. This is always an educational experience.

#FossilFriday This morning we were shown a Ruby Ranch wood site preserving insect frass (poop). More importantly the site looks like extremely rare pollen site near Aptian-Albian boundary...fingers crossed. Very promising..screen wash for micros..too... @utahpaleo-ufop.bsky.social

Checked out the old Smith homestead on east side of San Rafael Swell. There is either an unmapped fault to east (we had geological map) or there is a very thick Cedar Mt section capped by a large fossil lake. Another trip to investigate. @jlivelypaleo.bsky.social @utahpaleo-ufop.bsky.social

Some great geology on the south side of the Abajo Mts. Is that a sauropod track in the Morrison Formation? @utahpaleo-ufop.bsky.social @paleontologizing.bsky.social @jeremybroberts.bsky.social @andrewtracks.bsky.social

Heads up that the Field Museum is hiring a vertebrate paleontology collections manager: www.fieldmuseum.org/landing/care...

It’s Trilobite Tuesday! In 1698, Ogygiocarella became the first trilobite to be described & illustrated in scientific literature. But when it was first discovered in English outcrops, it hadn’t been recognized as a trilobite yet. In fact, the Ordovician species was referred to as a “flat fish.”

Describing and sampling J/K boundary on cut on SR 191 sw of Blanding lotsof thin section s to come big uppermost Morrison "bauxite" samples from laterite to slab. Ferrugenous paleosols of Yellow Car cool too. Section measured, but lots of work remains. @utahpaleo-ufop.bsky.social

In the field for the next week. First off, heading down into the Blanding Basin of southeastern Utah with mapping program to field check maps and provide insights of mapping mid Mesozoic formation contacts for up coming mapping projects. @utahpaleo-ufop.bsky.social @paleontologizing.bsky.social

For anyone interested in more details, the book that's heavily referenced in this story is fantastic, and #philsci people will also be interested in the central role played by Ludwig Fleck: bookshop.org/p/books/fant...

For #FossilFriday an amazing fossil from the largest dino Museum in the world' Shandong Tianyu Museum of Nature, China. This Beipiaosaurus specimen knocked my sox off. Play with this 3D model, we made out of my photographs through the glass. sketchfab.com/3d-models/be... @utahpaleo-ufop.bsky.social

Remember to check your kids candy for paleontology! #paleontology

Certainly resolves the debate. I love how paleontology knows so much, while knowing so little. www.nature.com/articles/d41... @paleontologizing.bsky.social I think your next twitch is spoken for....lol

Loosing the PRI would devastate US science. Any level donation, spreading the word helps. #FossilFriday #SaveScience priweb.donorsupport.co/page/FUNWALK...

As someone who has worked hard to bring economic benefit to the state of Utah as it preserves one of the most complete fossil bearing rock sequences especially in the world through bringing conference to Utah and developing tourism & educational opportunities; this is really depressing news!

Delighted to share our special ‪collection of 24 landmark papers in vertebrate palaeontology published in @journalsystpal.bsky.social in the last 15 years, assembled to coincide with #SVP2025 #2025SVP. All these papers are free to access now and through November: www.tandfonline.com/journals/tjs...

I will be speaking on the exciting data (science) from Utah pertaining to the J-K dinosaur mass extinction that wipped out the Morrison Dinos at end of Real Jurassic Park at Clark Planetarium at the Gateway downtown Salt Lake City, Thursday evening Nov. 13th. www.eventbrite.com/e/how-fossil...

Fossils are cultural objects - and this is not some woke b*llshit that people come up nowadays to spoil the fun in #palaeontology; this classification actually has a long history. If you're curious how fossils became #culturalproperty under int'l law, check my new paper: doi.org/10.1093/lril...

Lost an important keystone of my Ph. D. committee. Don Eicher was an expert on Cret. forams and a great guy who was a great counterpoint to Erle Kauffman, " Captain Cretaceous." With Bill Cobban, ammonites and Bill Hay, paleoclimatology I had pretty amazing advisors. @utahpaleo-ufop.bsky.social

LARRY THE COLLARED LIZARD by Serena Supplee Thurs, Nov. 20th, 2025 2- 4pm A gathering to welcome Larry to his pad on public lands Mile marker 1 on SR 128 (The River Road) Light refreshments will be served Collaborative project of BLM and Canyonlands Natural History Association.

Our new paper is out in @science.org #ScienceResearch Our understanding of the dinosaurs at the very end of the Cretaceous is limited by few localities. What dinosaur biogeographic patterns were present leading up the K/Pg boundary? What can these tell us about end Cretaceous dinosaur communities

This is the second part of the work we covered here, highlighting that CO2 is the dominant forcer in temperature and sea level changes during ice age cycles. (It's also a great chance for others to cover; this has not been widely reported. There's even an old ice core now that can test this!)

To celebrate the Morrison ankylosaur monograph peer reviewed & getting type set; some Morrison ankylosaur osteoderms vs those I'm figuring in describing the new basal Cretaceous polacanthines (sp. A huge & B) for #FossilFriday. @utahpaleo-ufop.bsky.social

#FossilFriday...So what to highlight. I know a few fossils from pond in Monitor Butte Mbr. of the Chinle Fm. near the head of Red Canyon, se Utah. Lacustrine sites deserve more love! A small crustacean, a possible beetle electra, coprolites (100s present at margin of site), with plants and fish.

Certainly affects the validity of Greg Paul's Utetitan.....

Join us on Nov 11 at 7:30 PM for a FREE screening of Walking with Dinosaurs at the King Koal Theatre in Price, UT! Follow the Prehistoric Museum & our excavation of Gastonia & raptor fossils. Hang out afterwards for a Q&A w/ our curator, Dr. Joshua Lively, and see fossils excavated during filming.

25/ To recap, the fossil record of walruses spans about 16 million years or so and is surprisingly diverse, with seal-like species, gigantic long-skulled species, giants with upper and lower tusks, and long-tusked forms that lost their teeth, or were even more gigantic than the modern species. 🐬🦖

Their online fossil collection and resources in the Digital Atlas of Ancient Life allowed me to teach Paleontology labs online through the Covid lockdown and remains an incredible resource for anyone anywhere (let's face it, Ithaca isn't convenient to anywhere).

#DinoConUK 2025 happened in August: it was sorta like #ComicCon, but devoted to #dinosaurs! Palaeoart, cutting-edge science, merch including art, models, stickers and more. News on our 2026 event coming soon :) tetzoo.com/blog/2025/8/...

I spent 13 months of my life between 1978 & 1988 in various camps around Black Mesa as I conducted field work for both my MS & Ph.D. on the paleo-strat of the Mancos Shale around the circumference of Black Mesa. Message me for pdfs of the various resulting publications. @utahpaleo-ufop.bsky.social

Good reviews on my Morrison Ankylosaur manuscript, so I'm dealing with comments and moving forward on #FossilFriday So for all 14 Morrison ankylosaur sites, which pertain to Mymoorapelta and which to Gargoyleosaurus? Stay tuned... The new basal Cretaceous polacanthids are next.

Great new paper by Mannion & Moore 2025 on diplodocoid sauropods for #FossilFriday I love their latest phylogeny as it certainly supports the mass extinction of sauropods at the end of the Jurassic that is so well documented in eastern Utah. www.tandfonline.com/doi/epdf/10....

Had the amazing privilege earlier in the year to watch a lithographic limestone plate be made by one last plate makers in Germany. Each plate is cut and then hammered by hand into shape - and after having a go it's very skilled work. Currently they have no apprentices, so a truly dying art.

So yesterday a reporter asked Donald Trump about the writ of habeas corpus, and he had no idea what it was. "I don't know," he said. "I'd rather leave that to Kristi." Well, It turns out Sen. Hassan asked Kristi Noem about it in May, and this was Noem's response:

A newly minted name for Utah's largest dinosaur, Utetitan! Given the amount of time these latest Cret sauropods span, more than one taxon likely. I did not review this manuscript, so let the sauropod researchers weigh in. giw.utahgeology.org/giw/index.ph... @paleontologizing.bsky.social
