Bizarre Edestus Shark Tooth In Jaw Section - Carboniferous
This is a very unusual and hard to acquire offering of a fossil tooth and jaw section from the Carboniferous aged shark Edestus heinrichi. These rare teeth are recovered deep underground in the coal mines of Illinois.
Comes with a riker mount display case.
Edestus was a very unusual shark that is only known from fossils of teeth and jaw sections. It is estimated they could reach 20 feet in length, about the same size as a modern great white. Like its other relatives like Helicoprion it did not shed its teeth as they became worn. This caused the jaws to become elongated and resemble a monstrous pair of shears. It's unclear how these sharks would have caught and eaten their prey with this jaw configuration.
