Fossil Teeth in Egypt Point to a Diverse Shark Community in an Ancient Sea

Fourteen fossil shark teeth found in Egypt's desert suggest a varied shark fauna lived in a Cretaceous sea that once covered northern Africa. The discovery offers a glimpse of a marine ecosystem that has since vanished.

The find consists of fourteen fossilized shark teeth recovered from Egypt’s desert. Together, they suggest that more than one kind of shark lived in the Cretaceous sea that once spread across northern Africa. That body of water is gone today, leaving only fossil evidence. In paleontology, such remains help reconstruct ancient marine communities from limited material. This case adds another glimpse of a diverse shark presence in a vanished sea.
