For almost 50 million years, there was nothing around to eat the sharks called Physogaleus.

Physogaleus is a genus of very small prehistoric shark that originated during the Eocene epoch.


Era & DiscoveryEdit

Physogaleus lived during the Eocene to Miocene epoch, over 36-15 million years ago. They were one of the top predators of their time and region. However, they were prey for the apex predator Basilosaurus. It was first discovered in 1849.

Physical AttributesEdit

Physogaleus was a small shark, measuring about 6 feet (2 m) long. Additionally, it was also said to have teeth that strongly resemble the teeth of a tiger shark.

Behavior & TraitsEdit

These sharks hunted fish in the open ocean and also often lived in mangroves, where they ate Apidium, but were too small to attack creatures like a Moeritherium. However, these sharks were prey animals for the larger Basilosaurus.
