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.
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.
