Fig. 1. Anterior aspect of sacrum and pelvis of Pareiasaurus Baini, showing thelarge size of the neural spine and second pair (s.) of sacral ribs and the depthgiven to the pelvis by the downward reflection of the pubis (p.) and inter-pubic ossification (ip.). The pubic foramen (f.) is well seen on the left anterior angles on the iliac bones (il.) are seen to extend outward. Fig. 2.
