external comment

The coracoid is a triangular shaped-bone that usually has an anteriorly directed long process that may joins its counterpart in some fish groups. It may be perforated by the coracoid foramen or it may be notched dorsally and forms the scapulo-coracoid foramen together with a similar notch of the ventral margin of the scapula.[TAO]

external definition

Paired cartilaginous structures or endochondral bones located on the posterolateral portions of the zonal area of the pectoral girdle.[AAO]

Endochondral bone that articulates dorsally with the scapula and with the mesocoracoid when the latter is present, posteriorly with the lower two or three proximal radials and antero-ventrally with the cleithrum. The coracoid develops from the scapulo-coracoid cartilage. The coracoid is paired.[TAO]

taxon notes

In Theria, coracoid bones non-existent or fused with the shoulder blades to form coracoid processes[WP]. Procoracoid+coracoid are homologuous with coracoid of teleostomi. The coracoid is a triangular shaped-bone that usually has an anteriorly directed long process that may joins its counterpart in some fish groups. It may be perforated by the coracoid foramen or it may be notched dorsally and forms the scapulo-coracoid foramen together with a similar notch of the ventral margin of the scapula

terminology notes

see discussion in Kardong - suggests using procoracoid (anterior coracoid) for the element in birds, reptiles, amphibians and fish, and reserving coracoid for the new synapsid/therian structure.
