The medial condyle pro- jects more ventrally than does the lateral condyle. The fibula ap- pears to have articulated on the lateral epicondylar region where a shallow groove (f f, Fig. 8A) occurs. The femur of Massetog- nathus pascuoli is morphologically comparable to the femora of Pascualgnathus pokmskii and even the larger African genera in which ossification of the extremities was well developed (Jenkins, in press). In smaller forms, such as galesaurids, the femur appears to be diiTerent because of the lack of ossification of the extremities and trochanters. The tibia is a transversely slender bone, bowed somewhat an- teriorly. The two proximal articular facets, oval in outline and shallowly concave, are separated by a low, median ridge. The. B.
