|— Allen, about Hybodus|
Hybodus (name meaning "Humped Tooth") is a genus of prehistoric sharks that originated during the Late Permian to Middle Cretaceous periods. It was once a wildly successful prehistoric shark that became extinct hundreds of millions of years after it first evolved.
Era & DiscoveryEdit
Hybodus sharks appeared at the end of the Late Permian and then disappeared at the Early to mid-Cretaceous - from 250-90 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.
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.
