A 380 million year old discovery of “Dunkleosteus,” one of the largest and most terrifying sharks, revealed its remnants

The marine creatures of the Devonian period were typically tiny and timid, but Dunkleosteus proved to be the exception that proved the rule.

This enormous (about 30 feet long and three or four tons) armored ancient fish was almost undoubtedly the biggest vertebrate of its time and the largest fish of the Devonian seas.

Dunkleosteus resembled a giant undersea tank, with a thick body, bulging skull, and massive, toothless jaws, according to reconstructions.

It would not have been necessary for Dunkleosteus to be an exceptional swimmer, since its skeletal armor would have provided sufficient protection against the smaller, predatory sharks and fish of its salty environment, such as Cladoselache.

Due to the discovery of so many fossils of Dunkleosteus, paleontologists know a great lot about the behavior and physiology of this extinct fish.

An examination of Dunkleosteus jawbones revealed that this vertebrate could bite with a force of around 8,000 pounds per square inch, placing it in the same league as the much later Tyrannosaurus Rex and the even later megalodon.

Approximately ten species of Dunkleosteus have been discovered in North America, Western Europe, and northern Africa.
