@Fangirlsarah1996:
hese animals constitute an evolutionary gradation from primitive synapsid to early therapsid. The clade Sphenacodontia is used to designate the monophyletic group that includes sphenacodontids and all their descendants (including mammals), while Sphenacodontidae in the strict sense includes only specialised pelycosaurs, and not earlier more primitive members of the family like Haptodus, Palaeohatteria, Pantelosaurus, and Cutleria (in pre-cladistic classifications all included under the genus Haptodus). The clade Sphenacodontoidea is used by Laurin and Reisz 1997 to designate the most recent common ancestor of Sphenacodontidae and Therapsida and all their descendants, and is defined by certain features of the skull.
So proto mammals.

@DeadCowboy: They had scales and needed to bask in the sun to generate body heat...so on the outside they were more reptilian...but they paved the way for true mammals...like us.
Though it wasn't a dinosaur it was a VERY important creature indeed.
