This is a 13" long jaw section section of a crushing mosasaur (Igdamanosaurus aegyptiacus, formerly Globidens) from the famous phosphate deposits in the Oulad Abdoun Basin of Morocco. There are five teeth in the jaw, along with an unerupted tooth that can be seen on the medial side of the jaw.

There are repaired cracks and gap fill through the bases of some of these teeth, one tooth crown of which is broken in two. Multiple repaired cracks can be found through the jaw, with spots of gap fill where the bone crumbled away.

This jaw is accompanied by an acrylic display stand to assist with presentation.

Igdamanosaurus (formerly called Globidens) had semi-spherical, acorn-shaped teeth rather than the pointed teeth of most Mosasaurs. These rounded teeth were best suited for crushing tough armored prey like small turtles, ammonites, nautili, and bivalves.
