Systematics of the Rubidgeinae (Therapsida: Gorgonopsia)
2016
Overview
The subfamily Rubidgeinae, containing the largest known African gorgonopsians, is thoroughly revised. Rubidgeinae is diagnosed by the absence of a blade-like parasphenoid rostrum and reduction or absence of the preparietal. Seven rubidgeine species from the Karoo Basin of South Africa are recognized as valid:
Aelurognathus tigriceps
,
Clelandina rubidgei
,
Dinogorgon rubidgei
,
Leontosaurus vanderhorsti
,
Rubidgea atrox
,
Smilesaurus ferox
, and
Sycosaurus laticeps
. Rubidgeines are also present in other African basins:
A. tigriceps
and
S. laticeps
occur in the Upper Madumabisa Mudstone Formation of Zambia, and
D. rubidgei
,
R. atrox
, and the endemic species
Ruhuhucerberus haughtoni
comb. nov. and
Sycosaurus nowaki
comb. nov. occur in the Usili Formation of Tanzania.
Aelurognathus nyasaensis
from the Chiweta Beds of Malawi also represents a rubidgeine, but of uncertain generic referral pending further preparation. No rubidgeine material is known outside of Africa: the purported Russian rubidgeine
Leogorgon klimovensis
is not clearly referable to this group and may not be diagnosable. Phylogenetic analysis of rubidgeines reveals strong support for a clade (Rubidgeini) of advanced rubidgeines including
Clelandina
,
Dinogorgon
,
Leontosaurus
, and
Rubidgea
. Support for
Smilesaurus
as a rubidgeine is weak; it may, as previous authors have suggested, represent an independent evolution of large body size from an
Arctops
-like ancestor. Temporally, rubidgeines are restricted to the Late Permian, first appearing in the
Tropidostoma
Assemblage Zone and reaching highest diversity in the
Cistecephalus
and
Daptocephalus
assemblage zones of the Beaufort Group.
