Abstract
The morphology of the skull of Promoschorhynchus platyrhinus (Moschorhinidae) from the
Daptocephalus-zone (Upper Permian) of South Africa) is described with special reference to the
palate and posterior part of the skull. Promoschorhynchus is compared with Moschorhinus and considered
to be a vaild genus mainly differing from Moschorhinus in retaining a longer snout, and in
possessing a more primitive morphology of the palatal plates of the premaxillae and vomers.
Promoschorhynchus also differs from Moschorhinus in having developed a sharp crista choanalis and a
fairly broad epipterygoid. The composition of the South African Moschorhinidae is briefly discussed
and is considered temporarily as consisting of five genera: M oJchorhinUJ (.1 = TigriJuchuJ).
CerdoPJ, PromoJchorhynchUJ and Hewittia. TigriJuchUJ and MOJchorhinuJ are probably synonyms.
