Fig. 7

Morphological variation of pectoral fins in Protacanthopterygii, Stomiati and Paracanthopterygii. The black circle indicates the increase of proximal radials. The white circle indicates the decrease of proximal radials. The white triangle indicates the loss of the mesocoracoid. The black triangle indicates the change in connections of distal radials and fin rays. The cladogram (phylogenic relationships) was drawn based on [19] and [20]
