In rays, the pectoral girdle is attached to the fused anterior section of the vertebral column (synarchial condition) and also, by way of the propterygium of the pectoral girdle and antorbital cartilage, to the nasal capsules of the skull. Unlike the condition in tetrapods, the pectoral girdle in bony fishes usually has no attachment to the vertebral column and instead attaches to the back ok the skull via the posttemporal bone. Rather than dividing bones into cartilage and dermal, as done for the skull, it seems more practical to present the bones in sequence from the skull to the girdle bones themselves.
