Abstract:
Femur was a short massive tubular long bone and shaft was slightly curved and had four surfaces and two borders. The proximal extremity was composed of the head with distinct neck and trochanter major. The large distal extremity consisted of a trochlea on its cranial surface and two cylindrical condyles on the caudal surface which were separated by the intercondyloid fossa. Patella was not observed. The tibiotarsus was the strong and longest bone in the hind limb and was twice the length of the femur. It presented a shaft and two extremities. The lateral surface of the shaft had a distinct rough fibular crest near the proximal extremity. The proximal extremity consisted of two condyles which articulated with the femur and two ridges medial and lateral both of which were separated by an intervening Cnemial crest. The smaller distal extremity showed a trochlea on its cranial surface which continued caudally as condyles. An extensor canal was observed on the anterior aspect of the distal extremity just proximal to the trochlea. The fibula was placed along the lateral border of the tibia and extended to two third of the length of the tibia.
