In 5018 the internal trochanter forms a long ridge extending on to the shaft, but it does not extend far proximally, so that the intertrochanteric fossa is long. The pubo-ischio femoralis internus ridge is low. The distal end is well expanded. In 11936 the femur is more robust. In K306 the right femur

The pubo-ischio femoralis internus ridge is low. The distal end is well expanded. In 11936 the femur is more robust. In K306 the right femur is a larger, heavier bone than the left and is certainly not of the same individual and may be of a different species. The distal ends are only moderately Fig. 43. Femora.

In K317 the internal trochanter forms a short, thickened ridge proximal to which lies a long, deep inter-trochanteric fossa. Scymnosaurus (figs. 44, 45, 46^, b and c, 47) In this genus the femur is fairly well represented. In 11557 there is a good, well-preserved femur, in 11597 a proximal end, in 12118 a proximal end, in 12193 a distal and proximal end, and in 12262 and K352 a poorly preserved but nearly complete femur. In the three complete femora there is a greater amount of twist or rotation of the t^vo ends on the shaft relative to each other than in the femur of all the other pristerognathids as hitherto described. This twist or rotation is an anti-.
