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.
MNHN 9587 was originally assessed as 'Ichtyosaurus missouriensis', [7] while RFWUIP 1327 was described as 'Mosasaurus maximiliani'. [8] Later both specimens were confirmed to belong to the same individual and the species name was established. Skull of Mosasaurus missouriensis holotype RFWUIP 1327 with a cast of MNHN 9587. Sarabosaurus dahli ...
They ranged in size from some of the smallest known mosasaurs (Carinodens, 3–3.5 meters), to medium-sized taxa (Clidastes, 6+ meters), to the largest of the mosasaurs (Mosasaurus hoffmannii) potentially reaching about 13 m in length.
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 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]
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.

Platecarpus was often regarded as the most common genus of mosasaur in the Western Interior Sea during the deposition of the Smoky Hill Chalk in Kansas, and Platecarpus ictericus was regarded as the most commonly occurring species. [5] However, scientists now consider it to be of the paraphyletic genus. Therefore, some species were reassigned ...
