Dunkleosteus terrelli, was a member of the extinct genus Dunkleosteus, it roamed the ocean during the Late Devonian, about 358 to 382 million years ago, measuring to 8.79 m (28.8 ft) long and 1 tonne (1.1 short tons) in weight, the Dunkleosteus was a hypercarnivorous apex predator of its time. Few other placoderms, save, perhaps, its contemporary Titanichthys, rivaled Dunkleosteus in size.
Dunkleosteus was probably a relatively slow but powerful swimmer, thought to have dwelt in diverse zones of inshore waters. Fossilization tends to have preserved only the especially armored frontal sections of specimens, thus it is uncertain what exactly the hind sections of this ancient fish were like
Dunkleosteus terrelli 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. This mechanism allowed D. terrelli to both achieve a high speed of jaw opening, opening their jaws in 20 milliseconds and completing the whole process in 50–60 milliseconds, comparable to modern fishes that use suction feeding to assist in prey capture.
