4.1" Mosasaurus Jaw Section

This is a small jaw section of Mosasaurus beaugei from the Upper Cretaceous phosphate in the Oulad Abdoun Basin of Morocco. There are are two teeth exposed and the tip of a third unerupted tooth poking out from the jawbone. It's pretty rare to see jaw sections with the teeth still in place like this. One tooth has been repaired but other than that there is no repair, restoration or compositing on the piece.

You will see hundreds of purported Mosasaurus jaws and jaw sections available at rock shops, shows and online, but nearly 100% of them are fakes. They are crudely constructed using plaster or modern animal bones with real Mosasaurus teeth mounted in them. Real Mosasaur jaws with teeth still in place are fairly rare.
