Hyneria was a giant lobe-finned fish of the Devonian period in the U.S. It was up to 4 meters (13 feet) long and ate small sharks like stethacanthus, a 2-foot shark with a hammer-shaped dorsal fin, and early amphibians such as Hynerpeton. Hyneria was one of the larger lobe-finned fishes such as the 22-foot Rhizodus of the Carboniferous period. Fossil representations of Hyneria include several specimens of partial remains. In BBC's Walking With Monsters: Life Before Dinosaurs, The Hyneria jumped out of the water and started crawling on the land, pushing itself forward and then grabbed a Hynerpeton by the tail and jumped back into the water. In real life the Hyneria probably only used it's powerful fins to navigate through shallow water.
