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. Like the closely related Dimetrodon, Sphenacodon was a carnivorous member of the Eupelycosauria family Sphenacodontidae.

Sphenacodontidae (Greek: "wedge point tooth family") is an extinct family of sphenacodontoid synapsids. Small to large, advanced, carnivorous, Late Pennsylvanian to middle Permian "pelycosaurs".

Sphenacodontia is a stem-based clade of derived synapsids. It was defined by Amson and Laurin (2011) as "the largest clade that includes Haptodus baylei, Haptodus garnettensis and Sphenacodon ferox, but not Edaphosaurus pogonias ". [4] . They first appear during the Late Pennsylvanian (Upper Carboniferous) epoch.

Aug 6, 2016 · Sphenacodon also displays the large canine teeth at the front of its mouth for prey capture, and the shearing teeth at the back for cutting bite sized lumps of flesh. These teeth were typical for the later predatory pelycosaurs.

Sphenacodon is a genus of sphenacodont that lived during the Early Permian period. Sphenacodon was related to Dimetrodon. Sphenacodon made an appearance in a famous lost movie called The Lost Spider-Pit Sequence. In the movie, it became described as a huge two-legged lizard, and was inaccurately portrayed as being capable of eating humans.

It was a medium-sized terrestrial predator which probably constiututed the basal or primitive ancestral type of the Sphenacodontia. It shares many structural features of the skull and skeleton with the more specialised sphenacodontids, indicating they are closely related.
