Crâne de mosasaure d'espèce Platecarpus tympaniticus (squamates, mosasaures). Provenance : Smoky Hill Chalk, Kansas (aux Etats-Unis). Date : Crétacé supérieur, période du Campanien, 88 millions d'années avant notre ère. Collections du Muséum national d'histoire naturelle de Paris (France). Exposé à l'occasion de l'exposition "Un T-Rex à Paris" au Muséum national d'histoire naturelle de Paris (France) du 6 juin au 2 septembre 2018. Légende du fossile dans cette exposition : "Les mosasaures ne sont pas des dinosaures mais des reptiles marins, très répandus à la fin du Crétacé. Certains genres comme Globidens et Halisaurus sont connus aussi bien aux Etats-Unis qu'au Maroc. Ces animaux étaient d'excellents nageurs, capables de traverser l'Atlantique."

A 30-year-old fossil was hiding bones from a mysterious ancient sea monster
bone jaw Cretaceous fossil Mosasaurus new species skull
Fossils collected in Osaka more than 30 years ago have revealed a surprise hiding in plain sight: four previously unrecognized bones from a giant Cretaceous mosasaur. Among them is the first confirmed premaxilla—the frontmost bone of the upper jaw—ever identified in a Japanese mosasaur fossil. Even more intriguing, parts of the skull show unusual anatomical features that don’t match known mosasaurs, raising the possibility that the remains belong to an entirely new species.
