is a genus of cynodont
that lived in both Madagascar and Brazil,
during the Triassic. Given that these two locations would have still
been attached to Africa during the Triassic, it is likely that
Menadon was also present in parts of Africa,
though at the time of
writing no fossils have been found in Africa. Like other cynodonts,
Menadon would have been a small, squat
quadrupedal animal with short
limbs. Although cynodonts were often carnivorous, Menadon
placed in a group that is known to have been primarily if not
Menadon is closely related to genera such as Exaeretodon and Gomphodontosuchus.
