Seymouria was a reptile-like labyrinthodont (extinct amphibian subclass) from the early Permian of North America and Europe (approximately 280 to 270 million years ago). Seymouria was well adapted to life on land, with so many reptilian features it was first thought to be a primitive reptile. The dry climate of the Permian suited reptiles better than amphibians, but Seymouria had many reptilian features that helped it in this harsh environment. It had long and muscular legs, and may have had dry skin and the ability to conserve water. Seymouria, unlike amphibians and other early tetrapods, might have lived for extended periods of time away from water. If so, this would have allowed it to move about the landscape in search of insects, small amphibians, and other possible preys, such as the eggs of reptiles. Seymouriamorpha were a small but widespread group of limbed vertebrates (tetrapods) that have long been considered reptiliomorphs. Undated, no illustrator credited.
