15050 - Rare Large Igdamanosaurus (Globidens) Mosasaur partial Jaw with 2 Teeth Xystridura templatonensis indicating that this specimen hasThis is a unusual Mosasaur partial jaw with 2 teeth from Igdamanosaurus aegyptiacus, formerly assigned to the genus Globidens. Most Mosasaurs had sharp teeth that had evolved to grab slippery prey such as fish. Igdamanosaurus had semispherical teeth with rounded nubbin like points, which were much better suited for crushing tough armored prey like small turtles, ammonites, nautili, and bivalves. It comes from the Late Cretaceous (~70 million year old)
