Among osteichthyans, only basal actinopterygians retain the full complement of elements present in non-osteichthyan gnathostomes.[uncertain][VHOG] TAO:0000141 uberon VHOG:0001754 at this time we have no need to name a more specific 'pectoral fin bud' class, but we may in future Fin bud that develops into the pectoral fin.[TAO] forelimb - pectoral fin bud pectoral fin buds VHOG_RETIRED:0001259 EFO:0003430 pectoral fin bud A limb bud that develops into a forelimb or pectoral fin.
