2.9" Halisaurus (Mosasaur) Jaw Section With 6 Teeth

This is a beautiful jaw section with 6 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 all of the teeth are original, though several have been reattached and there are a few repaired cracks.

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.
