Dunkleosteus and company

The Devonian period, sometimes known as the "Age of Fishes," might be defined as the "Age of Sorting Out," as the countless creature types from the Cambrian explosion either evolved into something adapted for the long term or, in many cases, died out.  The trilobites might have dominated the biomass, as they crawled over the sea floor in billions, and they were not all small - this species was over two feet long.  but the highlights are still the fish, which evolved into some spectacular types.  Dunkleosteus is still king, though there was one species nearly as large - this guy.

So it would have been an interesting time to get in a little fishing....
