Onchopristus Numides, a fish from the past that ruled the waters. Its sword-like rostrum makes it a true marvel. 

Unlike modern sawfish, Onchopristis had large, blade-like teeth lining the sides of its elongated snout, or rostrum. These teeth acted as a powerful slashing weapon, used to stun or injure prey. Each tooth is sharply pointed and often displays beautiful natural enamel, sometimes with root or base structures still intact.

This creature is thought to be high on the menu of the infamous spinosaurus.
