Dunkleosteus is an extinct genus of arthrodire placoderm fish that existed during the Late Devonian period, about 358–382 million years ago. The largest species grew to 6 m in length, and weighing around 1 tonnes.

Dunkleosteus could quickly open and close its jaw, like modern day suction feeders, and had a bite force of 6,000 N at the tip and 7,400 N at the blade edge. Several fossils have been found in North America, Belgium, Marocco and Poland. Like other placoderms, Dunkleosteus had a two-part bony, armoured 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. Dunkleosteus may have also been among the first vertebrates to internalize egg fertilization, as seen in some modern sharks.
