Artists reconstruction of a Halisaurus. By Nobu Tamura
is a section of rock from the Phosphate mines in the Oulad Abdoun Basin of Morocco containing two Mosasaur jaw sections, as well as several other associated bones. There most likelymore material under the surface of the rock, not yet exposed. These fossils would have been from the small Mosasaur, Halisaurus arambourgi.

It's still in it's plaster field jacket and the entire piece measures 27x10.5" and is up to 4" thick. The two jaw sections both measure about a foot long. There is a small amount of stabilization to a few of the teeth and sections of the bone, but no other signs of repair or restoration.

We had been planning to prepare it ourselves, but it had been sitting in our warehouse for over a year due to lack of time to work on it. The from this location is soft enough that it can be prepared by hand tools, especially after wetting it and allowing the water to soak in.

These fossils are recovered as a by-product of the massive phosphate mining operations in the Oulad Abdoun Basin of Morocco. While isolation Mosasaur teeth are very common, jaw sections with the original teeth in place are fairly rare. Most jaw sections you see are composites, or outright fakes.
