| The caudal vertebrae have been fused into a single rod-shaped skeletal element that lies between the ilia, in effect moving the tail internally. |
| The ribs which connect the sacral vertebrae with the ilia are however large. |
| Caudal vertebrae were unfused, not yet forming the rodlike urostyle, but they did lie within the arch formed by elongated ilia. |
| The pelvic girdle consists of three paired elements, the ilia, ischia, and pubes, which are fused into a single piece with the synsacrum. |
| Any belt that pulls the ilia anteriorly in this manner risks greater trauma to the posterior weight bearing ligaments. |
| There are moderate depressions in the lateral surfaces of the ilia posterior and dorsal to the acetabulum. |
