1.1" Crushing Mosasaur (Igdamanosaurus) Tooth - Morocco
This is a 1.1" wide tooth of a Mosasaur (Igdamanosaurus aegyptiacus) from the phosphate deposits in the Oulad Abdoun Basin of Morocco.
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.
It comes from the massive phosphate deposits in the Oulad Abdoun Basin near Khouribga, Morocco. These deposits are mined for phosphate, one of Morocco's biggest exports. The fossils are collected as a byproduct of the mining operations, saving them from certain destruction by the rock crusher.
