An interclavicle is a bone which, in most

placentals) are the only tetrapods which never have an interclavicle, although some members of other groups also lack one.[1] In therians, it is replaced by the sternum which is similar in shape and function but forms via endochondral ossification (cartilage forming bone). The interclavicle, on the other hand, develops through intramembranous ossification of the skin. Monotremes
, although part of the mammalian class, do have interclavicles.
