Prognathodon
Prognathodon ('forejaw tooth') is an extinct genus of marine reptile belonging to the mosasaur family. It had protective bony rings surrounding its eye sockets, indicating it lived in deep water. its fossil remains have been found in the U.S.A (South Dakota and Colorado), Canada (Alberta), Belgium, New Zealand, Morocco and The Netherlands. Its teeth are similar to those of some Triassic placodonts so it may have lived a similar lifestyle, feeding on shellfish, large fish and sea turtles. A very large specimen found in Israel was for some time referred to as Oronosaurus, but is now regarded as a species of Prognathodon, P. currii. The recent discovery of 2 nearly complete fossils (one which included flippers) in Alberta, Canada have given scientists new data as previous fossils only contained the remains of the skull. One fossil included stomach contents. [2]
