Physogaleus

Physogaleus was a small prehistoric shark from the Eocene epoch. This species of shark is poorly known.

Facts
Physogaleus were prehistoric sharks. They were one of the top predators in the Eocene seas. Their only known predator was the large carnivorous whale Basilosaurus. These sharks were two metres long and mostly ate fish but they would still kill large animals if they had the opportunity like the monkey Apidium.

Whale Killer
A pair of Physogaleus was seen attacking a shoal of fish before being killed themselves by a Basilosaurus. Then,  a Physogaleus was seen killing an unsuspecting Apidium. Some were then seen swimming past a group of Moeritherium.
