Amazing fossil shark skeleton is the first of its kind
Skulls and a nearly complete skeleton offer our best look yet at a shark that lived about 360 million years ago.
Shark teeth are among the most commonly found fossils around the world, yet the cartilage-based skeletons of their owners were rarely preserved. As a result, researchers have no idea what many early sharks looked like, even if they were once very abundant.
That’s why paleontologists working in the eastern Anti-Atlas Mountains of Morocco were stunned to find several skulls and an almost complete skeleton from two species of Phoebodus, a primitive shark genus that, until now, was known only from its three-cusped teeth. Described this week in Proceedings of the Royal Society B, the fossils reveal that Phoebodus had an eel-like body and a long snout, which makes it look a lot like the frilled shark that still roams the
