Abstract
Cynodonts are very advanced mammal-like reptiles of the Permian-Triassic which are of special interest to evolutionists because they gave rise to
the Class Mammalia during Middle or Late Triassic
time. Cynodonts have been known from strata of
Early Triassic age in South Africa for over one
hundred years, and numerous specimens have been
collected and described. In recent years the record
of cynodonts has been extended into earlier and
later time zones, not only in southern Africa but
in East Africa, South America, Russia , China, and,
most recently, in North America. Much of the
material from outside of Africa has not yet been
fully described.
