Bell proposed that the Mosasaurini should be abandoned and that all members of the tribe should be incorporated into the Plotosaurini. While other scientists agree that a tribe containing Mosasaurus should be monophyletic, they argue that Mosasaurini should be the valid tribe. For example, in a 2012 study, Aaron LeBlanc, Caldwell, and Bardet ...
The subfamily is generally recognised as containing two subdivisions, the tribes Globidensini (Globidens and its closest relatives) and Mosasaurini (Mosasaurus and its closest relatives). A third tribe, the Prognathodontini (Prognathodon and its closest relatives, such as Plesiotylosaurus), is also used on occasion. [6] "
Mosasauria is a clade of aquatic and semiaquatic squamates that lived during the Cretaceous period. Fossils belonging to the group have been found in all continents around the world.
Both the genera Globidens and Prognathodon (sometimes classified as a globidensin, though most often not) have adaptations to a powerful jaw musculature. The ratio between the length of the supratemporal fenestra and the total length of the skull has previously been used as an improvised measurement for mosasaur bite force, and is quite high in these genera (0.27 in Globidens dakotensis and 0. ...
Mosasaurus (/ ˌ m oʊ z ə ˈ s ɔːr ə s /; "lizard of the Meuse River") is the type genus (defining example) of the mosasaurs, an extinct group of aquatic squamate reptiles.It lived from about 82 to 66 million years ago during the Campanian and Maastrichtian stages of the Late Cretaceous.
Jormungandr is an extinct genus of mosasaurid squamates from the early Campanian Pierre Shale of North Dakota, United States.The genus contains a single species, J. walhallaensis, known from a nearly-complete skull and partial skeleton.
Mosasaurs (from Latin Mosa meaning the 'Meuse', and Greek σαύρος sauros meaning 'lizard') are an extinct group of large aquatic reptiles within the family Mosasauridae that lived during the Late Cretaceous.
