In the human the coracoid exists as a small protuberance on the scapula. of changes brought about by the incorporation of parts of the primitive exoskeleton into the endoskeleton; its various bones can be related to bones, cartilages, and dermal scales of lower forms. For example, the shoulder blade or scapula is a cartilage bone of primitive origin among vertebrates, for its relation to a car- tilage bar in the lower fishes may be traced with some accuracy.
