Pectoral fin skeletons of Basal-Teleostei. A, B Lateral view of a pectoral fin skeleton of Gorgasia preclara (25 cm TL = total length); asterisk indicates an ectopic ossification point. C, D Lateral view of a pectoral fin skeleton of Heteroconger hassi (25 cm TL); asterisks indicate ossification points. E–I Pectoral fin skeleton of Osteoglossum bicirrhosum (7.5 cm TL), observed from ventral view (E), dorsal view (F), medial view (G, H) and lateral view (I). J–N Pectoral fin skeleton of Pantodon buchholzi (10 cm TL), observed from the ventral view (J, K), dorsal view (L), medial view (M) and lateral view (N). Cl, cleithrum; Co, coracoid; DR, distal radial; FR, fin ray; Mco, mesocoracoid; PR, proximal radial; Sc, scapula; Scl, supracleithrum; Sco, scapulacoracoid. Scale bars: 1 mm (E, J, L–N); 500 µm (A, C, F–I, K); 200 µm (D); and 100 µm (B)
