3.6" Fossil Pliosaurus (Stretosaurus) Bone in Cross-Section - England

This is a cut and polished Pliosaurus (Stretosaurus (Pliosaurus) cf. macromerus) bone that was collected from Port Mulgrave in North Whitby, England. The cross-sectional cut allows for the internal cell structure of the bone to clearly be seen. The fossils of several types of marine reptiles including ichthyosaurs and plesiosaurs are commonly found in this formation.

It comes with an acrylic display stand.

About Pliosaurs

A pliosaur is a type of marine reptile belonging to the broader group known as plesiosaurs, distinguished by its short neck, massive skull, and powerful jaws. Unlike their long-necked relatives, pliosaurs evolved a compact, muscular neck that supported an enormous head armed with thick, conical teeth designed for gripping and tearing prey. They lived during the Jurassic and Early Cretaceous periods and were fully adapted to life in the open ocean, using four large flippers to “fly” through the water with exceptional speed and control.

Pliosaurs were among the apex predators of prehistoric seas, occupying a role similar to modern killer whales or great white sharks. Fossil evidence shows that they fed on large fish, ammonites, sharks, and even other marine reptiles, including long-necked plesiosaurs. Some of the largest pliosaurs reached lengths of over 35 feet (10+ meters), making them some of the most powerful predatory vertebrates ever to inhabit Earth’s oceans.
