Dunkleosteus

Dunkleosteus is an extinct genus of arthrodire placoderm fish that existed during the Late Devonian period (about 358–382 million years ago) which is composed mostly of large, carnivorous fish compared to a shark in early evolution. The largest can grow up to 3-9 meters long and 3.6-4 tons in weight. Dunkleosteus had a two-part bony, armored exterior, which may have made it a relatively slow but powerful swimmer. Instead of teeth, Dunkleosteus possessed two pairs of sharp bony plates which formed a beak-like structure. The scientists said Dunkleosteus possessed a four-bar linkage mechanism for jaw opening that incorporated connections between the skull, the thoracic shield, the lower jaw, and the jaw muscles joined together by movable joints and producing high bite forces when closing the jaw and had a bite force of more than 8,000 pounds/square inch. This power compared to dinosaurs such as Tyrannosaurus rex and modern crocodiles.
