Holotype. 9081 Pelvic girdle X £. a. Lateral, b. Ventral two ventral elements are adequately represented. Associated with a snout identified as a galesuchid species there is the left half of a pelvis with a damaged iliac blade, a good pubis and an incomplete ischium. From this inadequate material it would appear that the oldest gorgonop- sians of the Tapinocephalus zone had a low, long pelvic girdle, flattish in its pubic part and V-shaped in its ischiadic part. The ilium was apparently low. Its blade has little or no anterior process, but with a well developed long but low posterior process. The supra-acetabular edge is sharp with only a weak supra-acetabular buttress, but with a distinct supra-acetabular notch. The ilium forms about half of the large outwardly facing acetabulum. The pubes form a flat pelvic floor, long but not very broad. The pubic tubera are weakly developed, but the lateral edge in Hipposaurus is strong and girder-like. Each pubis is pierced by a fairly large foramen lying some distance anterior to the posterior pubic edge, facing ventrally it is obscured in lateral view by the girder-like thickened outer pubic edge. Ventrally the two pubes do.
