Phoxinus phoxinus ( Linnaeus, 1758)

Fig. 16 .

Material and dimensions.—See Table 2.

Description.—The general shape is ovate with the posterior portion tapering and slightly pointed. The antero− and the posterolateral edges are pointed and slightly better developed than the more rounded antero− and posteromedial edges. All margins are faintly rounded, except the posterior margin, which is straight ( Fig. 16A 1, B 1 ) or slightly undulating ( Fig. 16C, D ).

Computer tomography (CT) of Recent Cyprinus carpio (Linnaeus, 1758) (BSPG 2003 IV 143) and its lapilli; 150 layers of frontal sections were carried out from the dorsal to the ventral side of the head. 3D reconstruction of the head with the position of the otoliths projected (A1), frontal section (layer 36), showing the position of lapillus and asteriscus (A2), and frontal section (layer 38), showing the position of sagitta and asteriscus (A3); right (A4) and left (A5) lapillus in dorsal views (A4 and A5 are digital photographs). B. Digital pictures of the otoliths of Recent Cyprinus carpio (Linnaeus, 1758): lapillus in dorsal view (B1), asteriscus in medial view (B2), and sagitta in medial view (B3) (posterior tip incomplete). Otoliths are represented as right ones (BSPG 2003 IV 156b, d, and e respectively).
