Description

Details

The genus of Mosasaur, the Tylosaurus, is one of the lesser known of the Moroccan Mosasaurs. Tylosaurus was among the group of the largest known Mosasaurs, with lengths up to 46 ft.

This specimen comes from the phosphate mines located near Khourigba, Morocco and are dated to the Upper Cretaceous Period (99-65 Million Years Old)

Mosasaurs are an extinct group of large marine reptiles. Their first fossil remains were discovered in a limestone quarry at Maastricht on the Meuse in 1764. Mosasaurs probably evolved from an extinct group of aquatic lizards known as aigialosaurs in the Early Cretaceous. During the last 20 million years of the Cretaceous period (Turonian-Maastrichtian ages), with the extinction of the ichthyosaurs and decline of plesiosaurs, mosasaurs became the dominant marine predators. They became extinct as a result of the K-T event at the end of the Cretaceous period, approximately 66 million years ago. Mosasaurs breathed air, were powerful swimmers, and were well-adapted to living in the warm, shallow inland seas prevalent during the Late Cretaceous Period. Mosasaurs were so well adapted to this environment that they gave birth to live young, rather than returning to the shore to lay eggs as sea turtles do.
