Ruling the Oceans

The Age of Fish began 500 million years ago, before there was life on land. Life-nurturing fresh water falls on the new land in the background, as a baby Dunkleosteus (bonefish) chases two adult Perleious. At full adulthood, the Dunleosteus will measure 11 feet 6 inches, with an exposed skull 2 feet long.
