The surface of the antitrochanter in Ciridops is unusually large mainly due to greater extension anteriorly.
A portion of this muscle in Ciridops extended into the gap between the corner of the iliac crest and the antitrochanter, unlike the other genera compared.
The antitrochanter serves as a brace to prevent abduction of the hind limb and to decrease stress placed on the femoral head during bipedal locomotion.
