a beautifully preserved and quite large tooth of one of the most fearsome predators to ever roam earth's oceans, the Mosasaur. This is a large tooth has been completely removed from the rock. These teeth are found in the Oulad Abdoun Basin of Morocco during phosphate mining operations and are Upper Cretaceous in age. There are several different types of Mosasaurs preserved in these rocks, and this tooth appears to be from Halisaurus arambourgi.

Halisaurus ("Ocean Lizard") was in the Mosasaur family and were small compared to other Mosasaurs reaching lengths of 3-4 meters. There are one of the more uncommon types of Mosasaurs present in the phosphate beds, with less that 5% of the teeth representing Halisaurus.
