Pantylus

Pantylus (from παν pan, 'all' and τύλος tylos, 'knob') is an extinct microsaurian tetrapod from the Permian period of North America.

Pantylus was probably a largely terrestrial animal, judging from its well-built legs. It was about 25 cm long, and resembled a lizard with a large skull and short limbs. It had numerous blunt teeth, and probably chased after invertebrate prey.
