Diictodon feliceps Diictodon (meaning "two weasel teeth") is an extinct genus of pylaecephalid dicynodont that lived during the Late Permian period, approximately 255 million years ago. Diictodon had disproportionally large heads that ended in a horny beak. There is a clear distinction between specimens having canine tusks and those lacking them, as tusked specimens are generally larger and more likely to develop a pineal boss. This probably reflects sexual dimorphism, with the tusked sex almost certainly being the male. Diictodon had strong arms and legs, as well as 5 sharp claws on each hand, and may have had keen senses of smell and sight.
