The giant sawfish lived in prehistoric oceans 90 million years ago along what is now North Africa, North America and Europe. It is the largest sawfish known, growing to an estimated length of 14 feet.

Similar to today's sawfish, it had a long rostrum saw which extended in front of the fish with rigid, tooth-like denticles. It is theorized to have been used to slash and stun prey or even predators like sharks and crocodiles. Sawfish teeth have been found embedded in Spinosaur jaws, proving these two beasts often clashed.

O. numidus lived on the bottom of shallow waters waiting for prey to swim past. Their electrosensitive saws helped the sawfish to detect any movement around them so they could spring to life at unknowing fish and crustaceans.

The denticles are in a barbed hook shape. The rostral teeth were the sideways teeth on the rostrum. It is believed that like sharks, these teeth are continually replaced throughout the animal's life.  

This tooth has slight repair.
