The top of the iliac blade is unfinished and was presumably continued in cartilage. Posterior Limh (Figure 13). Pelvic limb material is fragmen- tary and poorh^ represented. Portions of femora include the damaged proximal and distal ends of a right femur from MCZ 2406, an incomplete shaft from MCZ 2518, a damaged distal end of a femur from MCZ 2407, and the proximal end of a small femur and the distal end of another in scrap associated with MCZ 2404. The last named elements are about half the size of those from MCZ 2406 but the structure is the same. The femur is of the peculiar Trimerorhachis type, with a cylindrical shaft and expanded ends. There is a shallow depression on the ventral proximal surface, bounded anteriorly by a projecting trochanter. The outer edge of the latter curves inward toward the shaft distally. The posterior margin of the depression opposite the trochanter is not strongly developed, so that the Y-shaped pat- tern of ventral ridges common in this area (Romer, 1947) is lacking. The adductor crest is represented by a modest, narrow ridge. Distally, this ridge ends in the center of the ventral sur- face, a short distance above the end of the bone.
