Mosasaur, an extinct group of predatory marine lizards that competed with other marine reptiles for food during the Cretaceous Period (145.5 million to 66 million years ago). Mosasaurs were widespread in the oceans, and many were quite large, some measuring up to 17 meters (56 feet) long.The fossils of the earliest mosasaurs date back to about 98 million years ago, but they were not exactly the most diverse or widespread marine reptiles. Their success proper was due in part to sheer luck. About 92 million years ago, an extinction event occurred that was caused by large-scale underwater volcanic activity.

The last of the mosasaurs died out at the end of the Cretaceous period, 66 million years ago, when an enormous asteroid wiped out all the dominant reptilian clades of the Mesozoic era. Although they were great in size and number, they too could not escape extinction. Works Cited; Grigoriev, D.W. (2014).
