The femur is very robust, without a clear neck leading from the shaft of the bone to the head. The fourth trochanter manifests as a low, rough area rather than the pronounced knob or ridge present in most other archosaurs. With the exception of having a tapering (rather than rounded) medial condyle, "Prestosuchus" generally resembles other loricatans in the structure of the femoral head and distal condyles. The tibia is shorter than the femur but thick and expanded near the knee. A deep pit is present on the postero-medial portion of its upper expansion, as also observed in "Procerosuchus" and "Batrachotomus". The fibula is much more slender, developing a large knob-like "iliofibularis" muscle scar as in various other pseudosuchians. Near the heel, a deep depression is present on the rear of the fibula. This depression is an autapomorphy of "Prestosuchus", being lunate (crescent-shaped) in "P. chiniquensis" and elongated in "P. nyassicus".
