Paleo-Files: Dunkelosteus terrelli
Dunkelosteus terreli is a large, 4.1-meter (13 ft)-long placoderm fish that hails from the end of the Devonian in what is now the Cleveland Shale of Ohio around 362-360 million years ago. D.terreli was the largest species of the Dunkelosteus genus and if apex predator of its shallow tropical sea ecosystem alongside the basal shark relative Cladoselache, It could create suction to bring smaller fish into its mouth by quickly opening and closing its jaws, and its bite force is widely considered to be among the strongest of any vertebrate loving or extinct. Fossils also showed that adult Dunkelosteus were also cannibalistic towards smaller, younger members of their own kind.
