Really Cool 8.1" Mosasaur (Eremiasaurus) Jaw Section

 
 
 
 
This an nicely prepared and really interested jaw section (yes, a real one) of a Mosasaur (Eremiasaurus heterodontus). The jaw section is 8.1" long, mostly removed from the rock and mounted on a base for display. One of the really cool aspects of the piece is several of the unerupted teeth are exposed and can be seen, growing inside the jaw.

What makes this jaw section so special is there is NO RESTORATION OR COMPOSITING to the jaw and the teeth have not been remounted. The rock was stabilized and an artificial rock base was created allowing the jaw to display very aesthetically on a flat surface. There are several repairs to the teeth but that's it.

It comes from the Upper Cretaceous, phosphate deposits in the Oulad Abdoun Basin of Morocco. There are many several types of Mosasaurs in these deposits but this one is Eremiasaurus heterodontus (LeBlanc, A.R.H., Caldwell, M.W. and Bardet, N. 2012).

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.
