Abstract - The skeletal anatomy of the Early Triassic (Induan) procolophonid reptile
Sauropareion anoplus is described on the basis of three partial skeletons from
Vangfontein, Middelburg District, South Africa. Together these three specimens
preserve the large majority of the pectoral and pelvic girdles, articulated
forelimbs and hindlimbs, and all but the caudal portion of the vertebral column,
elements hitherto undescribed. Our phylogenetic analysis of the Procolophonoidea
is consonant with previous work, positing S. anoplus as the sister taxon to a
clade composed of all other procolophonids exclusive of Coletta seca. Previous
studies have suggested that procolophonids were burrowers, and this seems to
have been the case for S. anoplus, based on comparisons with characteristic
skeletal anatomy of living digging animals, such as the presence of a
spade-shaped skull, robust phalanges, and large unguals.
