In Depth
Ctenorhachis is a genus of sphenacodont that lived in North America during the Permian. Although the skull of Ctenorhachis is unknown, the available fossil material for the genus show that Ctenorhachis was a sphenacodontid. So far all members of the Sphenacodontidae were predators in life, so by extension we can conclude that Ctenorhachis would have been a predator as well.
