Bargain, 1.4" Fossil Plesiosaur (Zarafasaura) Tooth In Rock - Morocco
This is a 1.4" long, partial tooth of Plesiosaur (Zarafasaura oceanis), from the Upper Cretaceous 145-66 million years ago. Note the bone fragments contained in the sandstone.
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.
