The coracoid, mesocoracoid, and scapula are endochondral bones and form the primary pectoral girdle; the remaining are dermal elements and form the secondary pectoral girdle. Posttemporal ().

The coracoid, mesocoracoid, and scapula are endochondral bones and form the primary pectoral girdle; the remaining are dermal elements and form the secondary pectoral girdle. Posttemporal (). The posttemporal is an elongated bone and located at the posterolateral side of the neurocranium. It overlaps the epioccipital dorsally and su- pracleithrum ventrally. Generally, two conditions are present in shape of the posttemporal in Phoxinus. The post- temporal expands at its ventral portion in P. erythrogaster, oreas, brachyurus, and cum- berlandensis, therefore the dorsal portion of the bone is narrower than the ventral one (TS 185[ 1]). The ventral portion does not expand in other species of Phoxinus and in the out- groups (TS 185[0]). The bone partially overlaps the dorsal side of the pterotic in P. cum- berlandensis, oreas, erythrogaster, and eos (TS 186[1]). In P. cumberlandensis, more than half of the bone overlaps the pterotic; in P. oreas and eos, a small posterior portion of the.
