1.3" Fossil Plesiosaur (Zarafasaura) Tooth - Morocco
This is a 1.3" long, tooth of the large dinosaur-aged, marine reptile Zarafasaura oceanis, from the Oulad Abdoun Basin in Morocco. It's small but nicely preserved.
Plesiosaurs were 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 large sizes, some species as long as 17 meters, and caught slow moving prey. Plesiosaurs breathed air, and bore live young; there are indications that they were warm-blooded.
