An Onchopristus rostral spine from the Kem Kem Beds in Morocco. This extinct genus of sawfish lived during the Late Cretaceous, about 95–100 million years ago, in the same ancient river systems that once hosted Spinosaurus and Carcharodontosaurus.

The rostral spines formed part of the long, tooth-studded snout (rostrum) of the sawfish, which it used to slash through schools of fish. This specimen shows fine preservation with natural color and texture.

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