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

in Big Blue Killer Whale

Physogaleus is a genus of small prehistoric shark that originated during the Early Eocene epoch in what is now Africa. Only 2 meters long, this was a relatively small medium-sized shark. In the episode "Big Blue Killer Whale", several of these sharks were brought back to the park from the Late Eocene 36 million years ago. They reside in the Primeval Aquarium exhibit of the park.

FactsEdit

Era & DiscoveryEdit

Physogaleus lived during the Eocene to Miocene epoch, over 56-15 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 are only known from their fossil teeth and isolated vertebra. 

Physical AttributesEdit

Physogaleus was a small shark, measuring about 6 feet (2 m) long and weighing around 200 pounds. Additionally, it was also said to have teeth that strongly resemble the teeth of a tiger shark, but smaller. 

Physogaleus teeth are smaller than those of true tiger sharks, lacking the heavy serrations typical of Galeocerdo, are more slender and can be twisted toward the crown.

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.
