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]

pectoral fin bud, pectoral fin buds

While the skeletons of teleost pectoral fins and tetrapod forelimbs are homologous at the level of endoskeletal radials, teleosts and tetrapods do not share homologous skeletal elements at the level of 'individuated' pro-, meso-, and metapterygia. Among osteichthyans, only basal actinopterygians retain the full complement of elements present in non-osteichthyan gnathostomes.[uncertain][VHOG]
