Plesiosaur Tooth Fossil | Maastrichtian, Late Cretaceous | Oulad Abdoun Basin, Morocco | 40–50mm

A genuine fossil tooth from a marine reptile of the order Plesiosauria — an extinct group of large, long-necked marine reptiles that inhabited the world's oceans during the Mesozoic Era. This specimen was recovered from the phosphate-rich sediments of the Oulad Abdoun Basin, near Khouribga, Morocco, a locality of international renown for its exceptional preservation of Late Cretaceous marine vertebrates.

Dating to approximately 66–70 million years ago (Maastrichtian Stage, Late Cretaceous), the tooth measures 40–50mm in length and displays the characteristic elongated conical form and longitudinal ridging associated with piscivorous plesiosaurs — well adapted for seizing fish and cephalopods.
