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.
The smaller mosasaurs may have spent some time in fresh water, hunting for food. The largest mosasaur Mosasaurus hoffmannii was the apex predator of the Late Cretaceous oceans, reaching more than 11 metres (36 ft) in length and weighing up to 10 metric tons (11 short tons) in body mass. [14]
Though represented by relatively small forms throughout the Turonian and Santonian, such as Clidastes, the lineage diversified during the Campanian and had by the Maastrichtian grown into the most diverse and species-rich mosasaur subfamily.
This list of mosasaur type specimens is a list of fossils that are official standard-bearers for inclusion in the species and genera of the squamate clade Mosasauroidea, which includes the line of predatory marine lizards that culminates in the mosasaurids.
This is a list of stratigraphic units from which mosasaur body fossils have been recovered. Units listed are all either formation rank or higher (e.g. group). Units listed are all either formation rank or higher (e.g. group).
