Our knowledge of Early Jurassic palaeobiodiversity in the upper Elliot
Formation of South Africa has increased markedly in recent years with the
discovery of new fossils, re-assessments of previously collected material
and a better understanding of Stormberg Group stratigraphy. Here, Ngwevu
intloko, a new genus of upper Elliot basal sauropodomorph is named on the
basis of a complete skull and partial skeleton (BP/1/4779) previously
assigned to Massospondylus carinatus. It can be distinguished from all
other basal sauropodomorphs by a combination of 16 cranial and six
postcranial characters. The new species is compared to a small ontogenetic
series of M. carinatus as well as to a range of closely related taxa.
Taphonomic deformation, sexual dimorphism and ontogeny are rejected as
possible explanations for the morphological differences present between
BP/1/4779 and other taxa. Osteohistological examination reveals that
BP/1/4779 had nearly reached adult size at the time of its death at a
minimum age of 10 years.
