Among osteichthyans, only basal actinopterygians retain the full complement of elements present in non-osteichthyan gnathostomes.[uncertain][VHOG] ZFA:0000141 at this time we have no need to name a more specific 'pectoral fin bud' class, but we may in future forelimb - pectoral fin bud pectoral fin bud pectoral fin buds uberon pectoral appendage field
