I had the greatest time at @dinolabinc.bsky.social a couple weeks ago and now I can show off the mosasaur tooth I came home with 😁

Happy #FossilFriday! Pictured is a jaw fragment from a mosasaur, a large marine reptile. It was found in 85-million-year-old Cretaceous limestone along the Missouri River bluffs, which formed at the bottom of a shallow inland sea during that time.🏞️ #fossil #museum #UNSM #geology #naturalhistory

Originally, this specimen was labeled as Nanotyrannus, but those teeth are known for their distinct hourglass-shaped or pinched cross-section. The more oval cross-section is more common in tyrannosaurins like T. rex or Tarbosaurus than earlier tyrannosaurids like Daspletosaurus or Gorgosaurus.

A dinosaur tooth of an indeterminate theropod, possibly Tyrannosaurus rex from the Hell Creek Formation in Harding County, South Dakota, USA. The oval cross-section suggests T. rex, but it could be something else. #FossilFriday #dinosaur #fossil #paleontology #tyrannosaurus #tyrannosaurid #theropod
