The mosasaurs are another group of extinct marine lizards which lived in
Cretaceous seas. Some of these great reptiles grew to be as much as 50
feet long, and their great gaping jaws were filled with many sharp
recurved teeth (Pl. 41). Mosasaurs were present in the great Cretaceous
seas which covered many parts of Texas, and their remains have been
reported from both north and central Texas. One such skeleton was found
near Austin, and its skull is on display in the Texas Memorial Museum.
