Coracoid
Coracoid, one of two bones forming on each side the ventral portion of the pectoral arch in bony fishes, amphibia, most reptiles, and having their greatest development in birds and monotremes. They are absent in snakes, and in most mammals are reduced to a process of the scapula, which in man is somewhat like the beak of a crow, whence the name.
