Kosmoceratops richardsoni from Utah's Grand Staircase-Escalante National Monument has an amazing array of floppy horns on its frill. Reimagined here as the Sideshow Bob of ceratopsians. The holotype at the Natural History Museum of Utah includes an amazing skull prepared by Mike Getty. #FossilFriday

Join the Great Basin Chapter of Utah Friends of Paleontology for a hybrid meeting Thursday, April 10 at 7 PM. Dr. Nathan Ong will present: "Streamlining Fossil Inventory and Data Analysis Across U.S. National Parks." #paleontology Sign up to attend online at the link. utahpaleo.org/2025/03/31/a...

This #FossilFriday, let’s also celebrate #FractofususFriday! Here’s a cast of several #Fractofusus specimens growing around (and likely absorbing nutrients from) a large mass of decaying tissue on the #Ediacaran sea floor. From Mistaken Point, #Newfoundland.

Happy #FossilFriday, check out some darling crocodylomorph tracks! 200 million years ago, small and snappy distant-croc-relatives, like Protosuchus, darted and splashed along a ripple-marked lakeshore and through silty riverbeds, leaving behind their traces. (1/2) #paleontology #ichnology

#FossilFriday takes us back to the #Silurian (~430 MYA) for a classic example of planar close packing in nature -- a silicified favositid "honeycomb" #coral with many individual hexagonal corallites sharing adjacent walls. #FossilHill Formation, #ManitoulinIsland, #Ontario 🇨🇦 #Canada

Presenting the skull of one of the earliest theropod #dinosaurs for this #FossilFriday, Daemonosaurus chauliodus, from the Late #Triassic of New Mexico 🇺🇸. It was unearthed from rocks of the famous Chinle Formation, which outcrops across the Southwestern USA. #Paleontology #Science 🧵 1/

Happy #FossilFriday! Enjoy this maxillary tooth from an Allosaurus. Found in western Colorado on BLM lands. #BLMPaleo I love this tooth! Great resorption pit with a new tooth just starting to form inside. Such a great teaching specimen!

happy #fossilfriday! this is parapuzosia, a giant ammonite from late cretaceous africa, europe, and north america. it is the largest ammonite currently known, with some estimates putting its weight at over a tonne (art by callum pursall)

My first book, The Fossil Keeper’s Treasure, is out now! It’s illustrated by the amazing Nat Cardozo. Each page features embossed fossils you can touch. Every fossil tells a story, and every scientist started out as a curious kid. I can’t believe it’s finally here! #fossilfriday #booksky

Hadrosaur skin impressions with dorsal osteoderms at the Natural History Museum of Utah. Many hadrosaur fossils found at Grand Staircase-Escalante National Monument include skin impressions. #FossilFriday

Full description of our Scottish pterosaur, Dearc! The final piece of @nataliajagielska.bsky.social 's PhD in Edinburgh. Natalia did a sublime job working on Dearc, becoming a world expert on pterosaurs along the way. Read her work 👇 (open access!)

Happy #FossilFriday everyone! This is a #3Dprint of a bone from the #Triassic Thaynes Formation of #Idaho. Originally described as a skull bone from an #ichthyosaur, it turns out not to be. Come talk to @garyonyx-mcgoy.bsky.social and me at @nhmu.bsky.social #DinoFest this weekend! #IdahoPaleo

For #fossilfriday here is the little collection I gave made of toys and models based on species I gave named. I hope there will be a pterosaur one day to add to it.

Utah's Cambrian record is world class!! peerj.com/articles/105... Sadly, it is largely ignored in Utah, but attracts researches from around the world. @utahpaleo-ufop.bsky.social @andrewtracks.bsky.social @paleontologizing.bsky.social @cambriancam.bsky.social @jeremybroberts.bsky.social

Saturday and Sunday at the Natural History Museum of Utah. #FossilFriday

DinoFest is only a few weeks away! Our biggest event of the year returns January 25-26 🦖 Reserve your tickets now by clicking below.

We're having a white #FossilFriday here in Northern Alabama. A rarity for us, so I'm celebrating by sharing the rarest fossil in the collection: this Lacertasterias elegans starfish. These li'l guys are normally studied by loose individual plates! Here this guy is in all his 17+ armed glory!

Woohoo! Celebrating another #FossilFriday here up on the 🦋 Remembering the time I prepared an Archimedes bryozoan just to see if it could be done.

If you’ve bought, read, recommended, asked for, or otherwise talked up The Last Days of the Dinosaurs and When the Earth Was Green, thank you. The success of the books means I can write more books, tell more stories, and keep the lights on. www.undertheumbrellabookstore.com/s/search?q=R...

#FossilFriday Skull of the hadrosaurid Prosaurolophus in the preparation lab of the Science Museum of Minnesota

The newly identified trilobite Protolenus is seen in a 3D model reconstruction by Arnaud Mazurier, a researcher at the University of Poitiers in France.  #FossilFriday

The Barosaurus reconstruction at the Natural History Museum of Utah presents a scene with the giant animal mired and attacked by an Allosaurus pack. Uniquely, this setting and the walkway through it lets you view the sauropod from above and below its huge dorsal vertebrae. #FossilFriday

Presenting the #temnospondyl, #Siderops kehli, on display at the Queensland Museum Kurilpa in Brisbane, Australia for this #FossilFriday. It grew up to 2.7 m long & inhabited the rivers & lakes of Australia during the Early #Jurassic. 🧵 1/

#fossilfriday Baking soda not just for baking and deodorizing your fridge. It can also be used to clean fossils! Air abrasion is a way to remove matrix from a fossil gently revealing a fossils hidden beauty. Here I am removing matrix from a small fragment of Triceratops skull with baking soda.

Here’s an undescribed Pleistocene isopod preserved in East African gum copal for #FossilFriday!

#FossilFriday #FossilFridayAtoZ The tiny dragon, the Jurassic scansoriopterygid Yi

For #FossilFriday, me measuring a giant myriapod burrow preserved as a natural cast in a fluvial sandstone, Late Silurian (420+ mya) Grampians Group, Victoria, Australia. Photo from 2006 field work there, finally published on this research in 2021: www.tandfonline.com/doi/full/10.... 🧪🪨⚒️ #ichnology

Vancleavea campi, a Late Triassic archosauriform preserved with some of the most incredible osteoderms I’ve ever seen. Cast on display at the Smithsonian National Museum of Natural History. #FossilFriday

For #FossilFriday here is the partial skull and carapace of the recently described ‘carnivorous aetosaur’ from the Late Triassic of Texas. It provides significant new information about Coahomasuchus kahleorum.

If we did a Spotify Fossil Prep Wrapped for the last six decades, it might some look something like this! If you want to see more fossils prepared in our lab, donate to our funding campaign all this month! And if you can’t donate, please share! #FossilFriday www.givecampus.com/schools/Utah... 

A small Elrathia kingii trilobite from Utah's Wheeler Shale. This is he most abundant trilobite species in the USA. E. kingii inhabited the boundary between dysoxic (low oxygen) and anoxic bottom waters. E. kingii fossils consistently occur in strata formed in low oxygen levels. #FossilFriday

“New” fossils for #FossilFriday: this is an impressive brontothere thoracic vert I found low in the White River Formation of Wyoming. The neural spine is so long! Brontotheres might look like rhinos 🦏 , and the are perissodactyls, but last I understood they were on the horse stem! 🐴

Cutest fossil turtle in all of Manitoba 🐢 Toxochelys snout for #fossilfriday

Gryposaurus monumentensis with replica skull — Natural History Museum of Utah. Roughly 80% complete — a rare museum display of the actual bones supported by a steel armature. The mount was built with vibration isolation to prevent earthquake damage. Actual skull is displayed nearby. #FossilFriday

Asilisaurus is a puzzling little reptile. The Triassic creature has some traits that look dinosaur-like, and might indicate it’s an early relative of dinosaurs like Edmontosaurus and Triceratops, but it also has some ancient traits that would make it a protodinosaur. Either way, it’s adorable. 🧪

Did a day trip down to Mounds to get some data regarding Mancos Group field trip stops around Farnham Dome (north axis of San Rafael Swell). Hinge point for strat units!

For our first 🦣 Monday on 🦋, here’s the Huntington Mammoth from the Wasatch Plateau! This Columbian mammoth was excavated at over 2700 m in elevation. A bone disease that afflicted this old bull is currently being studied by an undergraduate at USU Eastern! #MammothMonday #FossilFriday

Okay, I'm recycling some cool fossils, etc.from that other social media group that I will soon dump. rare plant fossil from the Late Triassic of SE Utah found in 2023 (manuscript in prep). Androcycas cf. santuccii only known from PEFO! First occurrence in Utah.
