The asymmetry of the carpal joint and the evolution of wing folding in maniraptoran theropod dinosaurs
In extant birds, the hand is permanently abducted towards the ulna, and the wrist joint can bend extensively in this direction to fold the wing when not in use. Anatomically, this asymmetric mobility of the wrist results from the wedge-like shape of one carpal bone, the radiale, and from the well-de...
