ends, well preserved in one individual of the aggregate fossil. An ectepicondylar foramen is formed from the supinator process and ectiepicondyle. Radii and ulna are preserved in the aggregate and are about equal in length, about 83% of the humerus length. The radius is almost straight and the ulna slightly more robust. Two of the juvenile individuals of the aggregate have radii with a slightly bowed shape. The metacarpals and phalanges of H. scholtzi have a long and slender shape to them. Pelvic girdles are preserved in both fossils and shows the anteroposteriorly elongated ischium typical of synapsids as well as a blade like distal shape and a well-developed pubic foramen. The ilium is also elongated and rises anteriorly above the acetabulum. At the anterodorsal margin of the acetabulum the ilium and pubis connect posteriorly to form it. The pubis does not fuse to the ilium but instead twists to lay 90 degrees to the iliac blade. Femurs are preserved in both fossils and are slender, elongated bones with a sigmoidal curve. The proximal end turns up while the distal end curves down, forming the curved shape. Shaft diameter of the femur is 10% of the total length and has a trochanter widely separated from the head. Overall the femur is almost identical to that of Mycterosaurus.
