1.35" Fossil Plesiosaur (Zarafasaura) Tooth - Morocco
This is a 1.35" long tooth of the large dinosaur-aged marine reptile Zarafasaura oceanis, from the Oulad Abdoun Basin in Morocco. The tooth is in nice condition and there are several other fossils including fish vertebrae and a shark tooth associated with it.
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.
It comes from the massive phosphate deposits in the Oulad Abdoun Basin near Khouribga, Morocco. These deposits are mined for phosphate, one of Moroccos biggest exports. The fossils are collected as a byproduct of the mining operations, saving them from certain destruction by the rock crusher.
