5.6" Polished Pliosaur (Liopleurodon) Limb Bone - England

Polished Pliosaur (Liopleurodon) Limb Bone - England #280235

This is a 5.6" wide section of polished limb bone from a pliosaur (Liopleurodon sp.). The bone comes from the Middle Jurassic (160 million year old) Oxford Clay of England. Fragmentary bones are a fairly common occurrence in the clays of this formation, and this one has been cut and polished on one side to reveal the beautifully preserved, agatized and pyritized cell structure.

It comes with an acrylic display stand.

Liopleurodon is a genus of large, carnivorous marine reptiles belonging to the Pliosauroidea, a clade of short-necked plesiosaurs. They were an apex predator during the Middle Jurassic period when seas covered Europe.
