Kaikaifilu is an extinct genus of large mosasaurs that lived during the Maastrichtian stage of the Late Cretaceous, in what is now northern Antarctica.The only species known, K. hervei, was described in 2017 from an incomplete specimen discovered in the López de Bertodano Formation, in Seymour Island, Antarctic Peninsula.
The specific placement of Mosasauria within the Squamata has been controversial since its inception, with early debate focusing on the classification of the mosasaurs. Cuvier was the first scientist to deeply analyze their possible taxonomic placement through Mosasaurus. While his original 1808 hypothesis that the genus was a lizard with ...
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 ...
Plioplatecarpinae is a subfamily of mosasaurs, a diverse group of Late Cretaceous marine squamates.Members of the subfamily are informally and collectively known as "plioplatecarpines" and have been recovered from all continents, [4] though the occurrences in Australia remain questionable.
Khinjaria (meaning "dagger") is an extinct genus of plioplatecarpine mosasaurid from the Late Cretaceous Ouled Abdoun Basin of Morocco.The genus contains a single species, K. acuta, known from a partial skull and vertebra.
Tylosaurus proriger mounted skeleton in the Rocky Mountain Dinosaur Resource Center in Woodland Park, Colorado. This list of mosasaurs is a comprehensive listing of all genera that have ever been included in the family Mosasauridae or the parent clade Mosasauroidea, excluding purely vernacular terms.
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 ] "
Mosasauroidea is a superfamily of extinct marine lizards that existed during the Late Cretaceous.Basal members of this group consist of small semiaquatic forms with terrestrial limbs ("plesiopedal"), while laters members include larger fully aquatic paddle-limbed ("hydropedal") forms commonly known as mosasaurs.
