Out of the mud

Through much searching and meandering in the online scientific world I finally found the answer for today. Eryops was discovered, described, and named by E.D. Cope in 1877. Cope being one of the larger names in American paleontology we have discussed his life many times before. Eryops was discovered in the Admiral Formation, Lower Permian era, in Archer County, Texas. The Admiral Formation is a formation of rock consisting of mainly mudstone and limestone with some mixed in sandstone. The formation ranges from 200 to 240 feet thick in some areas. Fossils have been found in New Mexico and as far away as the East Coast of America as well, however. Eryops wasn't much of a globe trotter, but it was fairly widespread for a rather large amphibian.
