Wishbone of a chicken

The furcula (Latin for "little fork"; pl.: furculae) or wishbone is a forked bone found in most birds and some species of non-avian dinosaurs, and is formed by the fusion of the two clavicles.[1] In birds, its primary function is in the strengthening of the thoracic skeleton to withstand the rigors of flight.
