Tut Tran has put a huge amount of effort in shepherding this state of the art review of paleontology in Utah's National Parks and Monuments. giw.utahgeology.org/giw/index.ph... Paleontology in these NPS units will always be evolving and new things are already in the works.

For #FossilFriday: one of the very first fossils of the American mastodon ever discovered. This specimen was found at Big Bone Lick, KY, US, in 1739 by a French military expedition, then sent back to Paris for study. On display at the Galerie de Paléontologie et d’Anatomie comparée in Paris. 🧪

I want to give a special shoutout to those that donated to or advocated for childcare at the #JMIH25 meeting. Because childcare is available on site, I have been able to attend the meeting and present my research. It is a lifeline for early career researchers, particularly women!

Thinking abut the unique terminal swords on the ends of dacentrurine stegosaur tails on this #FossilFriday . They really do seem to fully fuse over the tip of tail. How to reconstruct (no evidence for parascapula spines) and how many taxa? Is Wyoming's Alcocasaurus a dacentrurine?

Remember, the zero line is the average from 1951 -2000. It would look even worse if the average for baseline started in the 1040s. I'M really hoping this means less snow for this old man to shovel in Salt Lake City while providing plenty of snowpack in our mountains. @jeremybroberts.bsky.social

Since we just found many new dino bones at the basal Cretaceous ferruginous paleosol site ("iron stone bonebed") including a second cervical ring spine. I feel we can diagnose polacanthid sp. C.

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

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.”
