🦈 Fossil Overview:

This is a RARE and well-preserved Asteracanthus magnus Fossil Shark Tooth, originating from the White Limestone Formation, dating back to the Cretaceous Period (~145 million years ago). It was discovered in Ardley Quarry, Oxfordshire, UK, an area known for yielding exceptional fossilized remains of ancient marine life.

Asteracanthus was a genus of Hybodontid sharks, an extinct lineage of cartilaginous fish that thrived during the Mesozoic era. Unlike modern sharks, Hybodontids had powerful crushing teeth adapted for preying on shelled organisms, making them significant predators of their time.

This fossil originates from the Alice Purnell Collection, one of the largest and most renowned fossil collections in the world. Fossils from this collection are highly collectible and hold significant paleontological value.
