It's the most bizarre shark. Called Hybodus.
— Allen, about Hybodus

Hybodus (name meaning "Humped Tooth") is a genus of Chondrichthyans that originated during the Late Permian period in what is now Europe. Measuring only 2 meters long, Hybodus was once a wildly successful prehistoric shark that became extinct hundreds of millions of years after it first evolved.

In the episode "Cruel Jurassic Seas", a number of five Hybodus was brought back to the park from Late Jurassic Europe 149 million years ago. They reside in the Primeval Aquarium exhibit in the park.


Era & DiscoveryEdit

Hybodus first appeared at the end of the Late Permian and then lived up until the Late Cretaceous from 260 – 65 million years ago.

The first fossilized teeth from Hybodus were found in England around 1845. Since then teeth (and dorsal spines) have been recovered from around the world.

Physical AttributesEdit

Hybodus measured about 6 – 8 feet (2 – 2.5 m) long, making it a modest shark in size. As one of the most bizarre prehistoric sharks, Hybodus had strange horns on the top of their heads.

Like all sharks, Hybodus possessed acute hearing, and therefore, the sound of splashing portrayed an animal in distress.

Behavior & TraitsEdit

When they bit into large prey, Hybodus twisted to get a chunk of flesh. These predators had acute hearing, and the sound of splashing betrayed an animal in distress. They also probably lived in the shallows, away from giant marine reptiles, including pliosaurs. However, they would go out to deeper water to feast off larger prey, such as Leedsichthys. They would also eat alongside fellow carnivores, such as Metriorhynchus.
