5.36 in. Rooted in Jaw Mosasaur Prognathodon Fossil Tooth - Morocco

Presented here is an authentic and original rooted Mosasaur Tooth from Morocco. The species of Mosasaur is the Prognathodon, which is one of the more well known of the Moroccan Mosasaurs. Prognathodon had protective bony rings surrounding its eye sockets, indicating it lived in deep water. 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.
As reptiles do, you can see the emerging tooth underneath the most forward facing tooth.

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.

Note : This is not a reconstructed tooth, it is as discovered with no repair and as found!
