Cisuralian
The Cisuralian is the first series/epoch of the Permian.

Dimetrodon
Dimetrodon is an extinct genus of non-mammalian synapsid belonging to the family Sphenacodontidae that lived during the Cisuralian age of the Early Permian period, around 295–272 million years ago. Steppesaurus and Dimetrodon are Prehistoric synapsid genera and Sphenacodontidae.

Holotype
A holotype is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described.
List of therapsids
This list of therapsids is an attempt to create a comprehensive listing of all genera that have ever been included in the Therapsida excluding mammals and purely vernacular terms.

Sphenacodon
Sphenacodon (meaning "wedge point tooth") is an extinct genus of synapsid that lived from about 300 to about 280 million years ago (Ma) during the Late Carboniferous and Early Permian periods. Steppesaurus and Sphenacodon are Prehistoric synapsid genera and Sphenacodontidae.
