Bell, Federico Fanti, Mark T. La famille tire son nom de la première espèce décrite, le mosasaure, . A frontal of the mosasaur Clidastes propython from the Beloe Ozero locality in the Saratov Region (Rybushka Formation, Campanian Stage, Upper Cretaceous) is described.

The investigated specimen differs from the frontals of other members of the genus Clidastes in the relatively straight lateral flanks. Field expeditions to Seymour, James Ross and Vega islands, Antarctic Peninsula, have resulted in significant specimens of mosasurs (marine lizards). Enough taxonomic diversity is now known to allow preliminary biostratigraphic assessment.

These specimens were collected from the Late Campanian levels of. GIANT MOSASAURUS HOFFMANNI (SQUAMATA, MOSASAURIDAE ). FROM THE LATE CRETACEOUS (MAASTRICHTIAN) OF PENZA, RUSSIA. Saint Petersburg State University, Universitetskaya Emb. Mosasaurid squamates were major components of the Late Cretaceous marine vertebrate faunas. By this time, this group was well diversified and achieved a worldwide distribution, as remains have been recov- ered from shallow marine deposits of all continents, including Antarctica.

Aspects of mosasaur dental ontogeny are well preserved in many fossils of these giant marine squamates.
