Description
Massive Dunkleosteus skull.
Fossil exoskeleton armored pieces of the skull, neck and chiseled jaws of this massive placoderm prehistoric fish that ruled the Devonian seas of almost 400 million years ago.
Dunkleosteus is an extinct genus of Arthrodira Placoderm fish that existed during the Late Devonian period, about 370 million years ago. Some of the species, such as D. terrelli, D. marsaisi, and D. magnificus, are among the largest arthrodire placoderms ever to have lived.
The largest species, D. terrelli, up to 20 ft long and 1 ton in weight, was a top of the food chain predator. Few other placoderms, save, perhaps, its contemporary Titanichthys, rivaled Dunkleosteus in size.
Placodermi first appeared in the Silurian, and the group became extinct during the transition from the Devonian to the Carboniferous, leaving no descendants. The class persisted in the fossil record for at least 70 million years.
Numerous fossils of some species have been found in North America, Poland, Belgium, and Morocco.
