Dunkleosteus terrelli, named after David Dunkle of the Cleveland Museum of Natural History, is an extinct species of placoderm fish that lived during the Late Devonian period some 382 million years ago. Dunkleosteus was a very large fish for the time, measuring almost 20 feet long and weighing around a ton; its size likely meant that it was an apex predator in its environment. Like other placoderms, Dunkleosteus' front half was covered in an exoskeleton of bone which probably made it a slow, albeit powerful, swimmer. It's most notable feature were its jaws: it didn't have any teeth, the large tooth-like structures were actually razor-sharp, self-sharpening extensions of the jawbones. It would use these nightmarish jaws to tear into prey with a bite force of up to 1664 PSI. Dunkleosteus went extinct 358 million years ago, making it a relatively successful genus overall.

Dude Dunkleosteus is the shit. They have a skull at the Tyrell Museum in Drumheller and once you get an idea of how big it is... man, it’s terrifying.
