Auriculatus Teeth

Otodus auriculatus: The Primitive Eared Giant

Before the Megalodon and the Angustidens, the oceans were ruled by Otodus auriculatus. Dating back to the Eocene Epoch (approximately 35 to 55 million years ago), these teeth are the definitive “Eared” fossils. They are characterized by their massive, jagged lateral cusplets and heavily serrated edges, marking a pivotal moment in shark evolution where the smooth-edged Otodus lineage began developing the serrations needed to hunt large marine mammals.
