[2]TaxonomyAdelphailurus was named by Hibbard (1934). Its type is Adelphailurus kansensis. It was assigned to Felidae by Hibbard (1934) and Carroll (1988); and to Machairodontinae by Martin (1998).[3][4][5]MorphologyIt was a cougar-sized animal and may have had habits similar to those of a cougar. Its body had the same shape as a cougar except for a long and compressed upper canine. This would place this cat into the "false-sabertooth" group. Apart from that Adelphailurus had a retained upper second premolar, which is unusual for a cat. Body massTwo specimens were examined by Legendre and Roth for body mass.[6]
