Recently hatched Gilmoreichnus Hermitanus following small water current. Early Permian tetrapods were \"water lizards\", in the sense that they were either amphibious or dependent on swamps for food and hydration. The swamps were tropical and rainfall was both local and from distant ocean warming and even from the tail-end of hurricanes. There may have also been tornadoes from the west. The El Pueblo tracksite exhibits scoring of mud surfaces by wind-blown sand and vegetation from very strong winds from the west. There was an alternation of rainy monsoons and periods of reduced moisture. This variety of weather in itself was promoting terrestrial evolution in advanced reptilians that learned to range further and further from one swamp to another in search of food and hydration. This slab is 1/2 inch thick and very solid.
