Our study on dinosaur climatic niche evolution and thermophysiology is out now in Current Biology! (1/18) Artwork by Davide Bonadonna #dinosaurs 🪶 🦖 🌡️ Link: cell.com/current-biolog…

Must admit that #Hoplophoneus looks kind of terrifying up close and personal, like something out of science fiction. Those are some wicked #fangs on this saber-toothed #nimravid! #FossilFriday #paleontology #fossils Perot Museum

The huge #claws of ground #sloths were undoubtedly impressive in life. These are just the bones on which they grew, so on the living animal the full claws were even larger! From Fannin County, Texas. #FossilFriday #paleontology #fossils Perot Museum #Pleistocene #IceAge

This “ugly” fossil has led to an important paleontological discovery: extinct saber-toothed cats called Homotheriums once roamed the Texas coast! Read more about the treasure inside and the storied history of this fossil here: jsg.utexas.edu/news/2024/05/u…

Collections team just found this little Early #Permian fish when unpacking a donated collection. The subtle details still visible in the tiny little scales are amazing! About 270 million years old, near Seymour, Texas. #FossilFriday #paleontology #fossils #fish Perot Museum

Found a small jaw labeled #Eryops in the #Permian collections. It has plenty of large teeth along the top of the jaw, but check out the granular patches on the inner surface. Maybe to help hold slippery prey? Archer Co., TX. #FossilFriday #paleontology #fossils Perot Museum

Done molding the #Tyrannosaurus tibia from Big Bend NPS! The colorful silicone rubber molds will make beautifully detailed casts. A bonus: the public saw every messy step of the process through the Paleo Lab windows. #FossilFriday #paleontology #fossils #dinosaurs Perot Museum

We have a few #fossils from #Miocene rocks east of Huntsville, TX, such as these big, beautifully preserved #Alligator osteoderms and teeth. Would be cool to add more from this Texas coastline paleo-ecosystem to the collection! #FossilFriday #paleontology Perot Museum

Can I tempt anyone with a big, toothy #Tylosaurus pterygoid for #FossilFriday? This beauty comes from the specimen we collected in the Ozan Fm of Fannin County, Texas two summers ago. It really cleaned up nicely! #paleontology #fossils #mosasaurs Perot Museum

A little dive into the #Devonian collections for #FossilFriday. Here's a beautiful little #trilobite (Ketternaspis?) from the Haragan Formation of Oklahoma. Such incredible, delicate spines on this little extinct sea-bug! #paleontology #fossils Perot Museum

A #skin impression made by a #dinosaur approximately 97 million years ago in the Arctic of Alaska. Not exactly sure what kind of dinosaur it was, but many fine details are preserved here. #FossilFriday #paleontology #fossils #Cretaceous Perot Museum

Part of an articulated series of 9 #sauropod vertebrae now being prepped on view in Perot Museum. Partly entombed in knobby sandstone concretion, with gorgeous preservation! From the Early #Cretaceous Antlers Fm northwest of Dallas, TX. #paleontology #fossils #dinosaurs

So many #mosasaurs in the collections! Their carcasses must have littered the #Cretaceous seafloor in north Texas. These 3 were each found just 30 to 90 minute drives from the Perot Museum, and are only the 'tip of the iceberg'. #FossilFriday #paleontology #fossils #lizards

How about a trio of #Otodus #megalodon teeth for #FossilFriday? Some beautiful examples from these mega-toothed #sharks. Collected in the Yorktown Formation (latest Miocene? to Pliocene) of North Carolina. #paleontology #fossils Perot Museum #teeth

An edge to the #sauropod block NW of Dallas! Bone(s) poking out left tip of concretion over 2 meters across. Need to find back side of block, then figure out how to move it. Huge "Thank you!" to volunteers who helped. #FossilFriday #paleontology #fossils #dinosaur Perot Museum

Are you seeing double on #FossilFriday? Nope. Just the #Tyrannosaurus tibia from Big Bend NPS and a cast with an amazing "nature-fake" paint job (not yet finished). Great work by Perot Museum Paleo Lab Manager Mariah Slovacek. #paleontology #fossils #dinosaurs #tyrannosaurs

What a difference a month makes! These #sauropod caudal vertebrae went from half-embedded in concretion to ready for study in no time. Great prep work on this Antlers Formation #dinosaur! #FossilFriday #paleontology #fossils #Cretaceous Perot Museum

Team opened a big whopping crate holding a huge #fossil log in the Perot Museum collections. This chunk of #Triassic tree from the #Chinle Fm has beautiful surface details, large branch stubs, and is as long as I am tall! #FossilFriday #paleontology

How about a short-stack of #ribs for #FossilFriday? Parts of 4 #sauropod ribs in a block from the Antlers Fm site NW of Dallas, being prepped on view in Perot Museum. The other ends are still trapped in a huge concretion in the field! #paleontology #fossils #dinosaurs
