This unique sawfish rostral tooth barb is approximately 90 million years old. Onchopristis, or “giant saw”, is a genus of extinct giant sawfish that lived in the Upper Cretaceous in or near North Africa. It had a long hard shovel-shaped snout called a rostrum. The saw-like rostrum, lined on both sides with modified tooth-like structures called denticles, were hooked and barbed. Onchopristis had an intimidating, 2.5 meter long rostrum which it would have used to unearth crustaceans at the bottom of shallow waters like sawfish do today.
