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.🏞️

A dinosaur tooth of an indeterminate carcharodontosaurid from the Grès supérieurs Formation in the Savannakhet Province of Laos. Possibly cf. Siamraptor suwati, but the size and morphology seems more derived. #FossilFriday

Majungasaurus is quite unique in being relatively "small" as the apex predator in its habitat. How many Majungasaurus does it take to kill a Rapetosaurus that's not already dying or a juvenile? I don't know. Maybe impossible.

A dinosaur tooth of a Majungasaurus crenatissimus from the Maevarano Formation in the former Mahajanga Province of Madagascar. This species of abelisaurid is one of the most common and abundant fossils in the deposit.

I'm a paleo-illustrator so if you like fossils and extinct species stick around!
First up : Portunatasaurus chasing fish in a wave during the late Cretaceous in what is now Croatia.
It's a potential early relative to the much bigger mosasaurs!

Two maxillae from the

As stated already, the "super croc" did not live with Spinosaurus (or Carcharodontosaurus), and this giant crocodylomorph was extinct and fossilized by that time. However, it did live alongside Suchomimus and Eocarcharia, as well as Ouranosaurus.

A crocodylomorph tooth of a Sarcosuchus imperator from the Elrhaz Formation in Gadoufaoua, Niger. Often referred to as the "super croc", this genus was not a true crocodilian; it also did not live with Spinosaurus as commonly portrayed in media.

Kinokuniya is primarily known as a bookstore, but the one in Shinjuku, Japan also has a fossil and mineral store.
Assuming the provenance was labeled correctly, the "Saurornitholestes" is likely an Atrociraptor. Although it's hard to tell without seeing those hooked serrations of the clade.

A fossilized appendage of an indeterminate radiodont from the Chengjiang Biota in Yunnan, China. These radiodonts or "anomalocarids" were all formerly assigned to Anomalocaris, but have since been moved into genera outside Anomalocarididae.
