9.5" Crushing Mosasaur (Igdamanosaurus) Jaw Section - Morocco

Crushing Mosasaur (Igdamanosaurus) Jaw Section - Morocco #220255

This is a 9.5" long lower jaw section section of a crushing mosasaur (Igdamanosaurus aegyptiacus, formerly Globidens) from the famous phosphate deposits in the Oulad Abdoun Basin of Morocco. The bone and tooth preservation is quite nice, with relatively little breakage which is considered to be quite unusual from this site. Jaws of this species and quality are extremely rare, and are seldom seen on the market! There are three teeth in the jaw including one of considerable size.

Repairs include cracks through the bone where it was found separated within the rock and glue stabilization for lasting integrity of the bone. Some of the teeth have undergone repair as well, with one tooth missing a portion of it, though this seems to be wear. The teeth are situated in their natural positions within the mandible. The jaw also features an unerupted tooth that may have been remounted.

This jaw is accompanied by a metal/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.

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.
