''Paleothyris'' had sharp teeth and large [[eye]]s: it was a [[nocturnal]] hunter. It was about a foot long. It probably fed on [[insect]]s and other smaller animals found on the floor of its [[forest]] home. ''Paleothyris'' was an early [[sauropsid]], yet it still had some features that were more [[labyrinthodont]]-like than [[reptile]]-like. Its skull lacked [[Skull#Temporal_fenestrae|fenestrae]], holes found in the skulls of most reptiles and mammals. == Related pages == * ''[[Pederpes]]'', an early [[Mississippian]] [[tetrapod]], 359–345 million years ago (mya). * ''[[Westlothiana]]'', from 350mya, either an early [[amniote]] or a sister group to the amniotes * ''[[Casineria]]'', from 340 mya, a basal [[amniote]]. * ''[[Protoclepsydrops]]'', from the middle [[Pennsylvanian]], 314 mya, probable earliest [[synapsid]] * ''[[Hylonomus]]'', from 312 mya, another early [[anapsid]] [[sauropsid]] * ''[[Archaeothyris]]'', from 306 mya, an early [[synapsid]] * ''[[Petrolacosaurus]]'', from 302 mya, the first [[diapsid]] [[sauropsid]] [[Category:Stem tetrapods]]
