2.1" Plesiosaur Tooth In Matrix - Great Preservation

This is a large and very well preserved tooth of the large dinosaur aged, marine reptile Zarafasaura oceanis. It's over 2 inches long and was collected from the phosphate mines in the Oulad Abdoun Basin of Morocco. The preservation is very nice, with great enamel and growth lines. The matrix is original, it has not been remounted.

Plesiosaurs where long-necked marine reptiles with four flippers that appeared in the Triassic and died out along with the dinosaurs at the end of the Cretaceous period. They reached quite larges sizes, some species as long at 17 meters, and caught slow moving prey. Plesiosaurs breathed air, and bore live young; there are indications that they were warm-blooded.

This species of of Plesiosaur was redescribed from Plesiosaurus mauritanicus to Zarafasaura oceanis in a 2011 paper which can be found at:
