Diictodon is an extinct genus of pylaecephalid dicynodont[5] that lived during the Late Permian period, approximately 255 million years ago.
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.
Their burrows could have been used to escape the heat of the desert, which was the dominant environment on the continent of Pangaea in the Late Permian Period.
Diictidon’s primary utilization of humeral excursion rather than forearm extension aided in employing rotation thrusting when burrowing.
