2.2" Halisaurus (Mosasaur) Jaw Section With two Teeth

This is a beautiful jaw section with two teeth of a Halisaurus ("Ocean Lizard") which was in the Mosasaur family. They were small compared to other Mosasaurs reaching lengths of 3-4 meters.

This jaw section is Upper Cretaceous in age and was collected in the phosphate mines in the Oulad Abdoun Basin of Morocco. Fossils of Halisaurus are quite rare compared to some of the Mosasaurs from these deposits. The jaw has been prepared completely free of the matrix and the teeth are original, though they were broken and reattached. This section would have been from the very front of the jaw.

Beware: Mosasaur jaws are one of the most frequently faked fossils. You can find hundreds of nearly identical looking jaws for sale described as authentic from many places both online, at gift shops and fossil shows. They are typically constructed using real Mosasaur teeth (which are quite common) mounted on a cast or molded jaw. Real jaws are quite rare finds.
