Mosasaur Fossil

A description about this fossil, which is located in the Johnston Geology Museum at Emporia State University: *This specimen was collected during the summer of 1967 two miles north of Elkader, KS, in SW Gove Co. It was found by a groupd of elementary teachers while on a field trip to Western KS as part of a science enrichment program under the auspices of the Flint Hills Elementary Science Project funded by the U.S. Office of Education, Department of Health, Education, and Welfare.* *Mosasaurs were elongate, lizard-like reptiles that were fully adapted for marine life. A snake like characteristic is seen in the structure of the jaw which is held to the skull by ligaments only. This gave freedom of movement at the back of the jaw and assisted in swallowing large objects.....* Part of the Cretaceous.
