Dicynodonts were herbivorous non-mammalian synapsids that were relatively
abundant on the landmass of Pangea from the Mid Permian to Late Triassic.
The dicynodont genus Endothiodon is well known from late Permian strata of
the Karoo Basin of South Africa. It is characterised by replacement waves
of internal tooth rows on the premaxilla and dentary; longitudinal ridges
from the premaxilla to the pineal crest; and a pineal foramen on a
prominent boss. Endothiodon is well-represented by cranial and postcranial
material in various South African museum collections. Recently, an almost
complete skeleton of Endothiodon (SAM-PK-K011271) was recovered from the
uppermost Pristerognathus Assemblage Zone of the Karoo Supergroup. It
comprises the skull and most postcranial elements preserved in
articulation. The present study identifies SAM-PK-K011271 as E. bathystoma
and we show that it is the second largest E. bathystoma specimen known to
date. Furthermore, the well-preserved skeletal remains enable us to present
the first comprehensive description of its postcranial anatomy.
