Fossil Find Is From Early Push-Up CreatureA 365-million-year-old arm bone fossil found in Pennsylvania came from one of the first creatures able to do push-ups, an evolutionary step that was necessary for animals to move from the sea to dry land. When the animal lived, there were no vertebrates on dry land, and the oceans were a place of fierce, toothy meat eaters living a predatory life of eat or be eaten. It was into this hostile environment that a two-foot-long animal that was more than a fish and less than a true amphibian made its brief appearance in the fossil record, said researcher Neil Shubin.
