homology_grouping
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]
