Greererpeton is an extinct genus of temnospondyl amphibian from the Early Carboniferous period (late Visean). It was about up to 1,5 m (5 ft) long.
Greererpeton was a highly elongated creature adapted for swimming. Its body had 40 vertebrae, twice as much as average, and a flattened skull of about 18 cm (7 in) long. The limbs were short and mainly used to steer the creature as it was propelled by its long tail. Some marks on the side of the skull indicate that Greererpeton had a lateral line, a sensory organ commonly found in fish. This showed that it was still a primitive amphibian. Its ears were poorly developed.
