Concurrent with this is an increase in the size of the pelvic limb. The most obvious morphological change in the legs is an increase in the robustness of the elements. In the wing there are several structures that undergo obvious and characteristic modifications with the loss of flight.</paragraph>

. In the fossils, the incisura capitis is directed more proximodistally, bringing it more in line with the shaft; this is caused by the entire proximal end of the humerus being tilted laterally relative to the rest of the element. By virtue of this tilting, the tuberculum ventrale becomes on the same proximal level as the caput humeri. The caput itself is considerably flattened and elongate. The crista deltopectoralis is thickened, reduced and rotated proximomedially in respect to the shaft. The crista bicipitalis is reduced. The shaft is curved and stout; however, this has not been preserved in the fossils. Other changes are seen in the fossil carpometacarpus. Compared to this element in the volant species, it is reduced, becoming shorter as well as stouter, os metacarpale majus is bowed in anterior view, and os metacarpale minus is more curved. Changes in the coracoid related to flightlessness include a more robust processus acrocoracoideus and a broader and more medially directed processus procoracoideus lacking the ventrally directed twist of the tip.
