Artinskian genera

Meganeuropsis, from Ancient Greek μέγας (mégas), meaning "large", νεῦρον (neûron), meaning "nerve", and ὄψις (ópsis), meaning "appearance", is an extinct genus of griffenfly, order Meganisoptera, known from the Early Permian Wellington Formation of North America, and represents the largest known insect of all time. Meganeuropsis existed during the Artinskian age of the Permian period, 290.1–283.5 mya. The genus includes two described species by Frank Morton Carpenter, fossil insect curator at the Museum of Comparative Zoology at Harvard University:

Orobates is an extinct genus of diadectid reptiliomorphs that lived during the Early Permian. Its fossilised remains were found in Germany. A combination of primitive and derived traits (i.e. autapomorphic and plesiomorphic) distinguish it from all other well-known members of Diadectidae, a family of herbivorous reptiliomorphs. It weighed about 4 kg and appears to have been part of an upland fauna, browsing on high fibre plants. thumb|left|Restoration

Arisierpeton is an extinct genus of synapsids from the Early Permian Garber Formation (Sumner Group) of Richards Spur, Oklahoma. It contains a single species, Arisierpeton simplex.
