About Coccosteus:

Yet another of the prehistoric fish that prowled the rivers and oceans of the Devonian period, Coccosteus had a well-armored head and (even more important from a competitive standpoint) a beaked mouth that opened wider than that of other fish, allowing Coccosteus to consume a wider variety of larger prey. Unbelievably, this smallish fish was a close relative of the biggest vertebrate of the Devonian period, the huge (about 30 feet long and 3 to 4 ton) Dunkleosteus.
