2.4" Fossil Plesiosaur (Zarafasaura) Tooth - Morocco
This is a 2.4" long, tooth from a large, dinosaur-aged plesiosaur (Zarafasaura oceanis). It was collected from the phosphate deposits near Khouribga, Morocco and is still partially embedded in the rock it was found in. There are a couple of repaired cracks in the tooth.
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 phosphate deposits 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.
