 The radius's proximal extremity is wider than its distal extremity; the ulna's proximal portion is also wide, about three times the thickness of the diaphysis.The metacarpals and a few phalanges are also preserved, showing that they both have laterally expanded extremities but that other than this the phalanges are cylindrical.The femora are both partially preserved, and each femur is quite robust, with an expanded head.
