With a length of over ten meters and razor-sharp teeth, the Pliosaur was a terror in the Jurassic ocean. It had its choice of options when devouring prey: swallow them whole with its massive mouth or tear them apart with its reinforced jaws. With these advantages, this aquatic reptile ruled the seas for 110 million years across the Mesozoic Era.

This specimen is a 2.132" polished piece of fossilized Pliosaur bone, recovered from the Lower Oxford Clay in Cambridgeshire, England. It dates back over 160,000,000 years old to the Jurassic Period, by which time Pliosaur had established itself as a terrifying predator of the seas. The fossil ships with a certificate of authenticity.
