1. The femur measured around, the tibiotarsus , and the tarsometatarsus. 2. The tibiotarsus was about 30 % longer than the femur. 3. It is the distal end of a left tibiotarsus . 4. The tibiotarsus has a narrower internal glenoid fossa of mammals ) is more protruded. 5. By 1925, Miller had assigned three more tarsometatarsi and an incomplete tibiotarsus to the genus. 6. In the pelvis, the tarsals are never fused in a separate astragalocalcaneum; a tibiotarsus is formed. 7. The lower leg is relatively long with the tibiotarsus having 137 % of the length of the thighbone. 8. It resembles the lanner falcon but is darker overall, and has blackish " trousers " ( tibiotarsus feathers ). 9. The adults showed a greater degree of skeletal fusion in the tarsometatarsus and tibiotarsus , and also more prominent muscle scars. 10. At the knee joint, the femur connects to the tibiotarsus ( shin ) and fibula ( side of lower leg ).
