In another world some 380 million years ago, a few members of a rising family of predatory placoderms finds themselves driven into brackish water in Gondwona. There they thrive and a few of them turn to moving up river in search of prey becoming freshwater fish, hunting in the new swamps and river litter covered river and lake beds. Soon they would colonize numerous waterway systems and would steadily modify themselves to thrive in them. They developed an ability to draw in air to supplement their breathing and expel waste CO2 out of modified gill slits and adapted their fins to better move around on the bottoms of the shallow pools. Occasionally some of their habitats would dry up and when that happened the ability to move from body of water to body of water was often a life saver. As such eventually a breed emerged which was well suited to live life on land.





A few species of lobe finned fish were on the same course, but ultimately they could not compete with their armor headed rivals which had a head start and gave birth to live young. In the oceans the relatives of these first fore-runners onto land would become the largest predators the world had seen up until this point. On land, the descendants of Dunkleosteus would reign supreme from the Devonian onward.
