cf. Leuciscus sp.

Fig. 25 .

Material, dimensions and stratigraphic range.—See Tables 1 and 4, and Fig. 32 .

Description.—The lapilli display a Leuciscus −like ( Fig. 15 ) regular shape with the medial and lateral margins bilaterally symmetrical to each other and with a prominent cranial umbo. The anterolateral and anteromedial edges are well developed and occur opposite to each other. However, these fossil lapilli reveal a rounded posterior margin whereas in the lapilli of Recent Leuciscus species the posterior margin is always steeply inclined.

Fig. 15. Utricular otoliths (lapilli) of Recent Leuciscus from wild catches in Germany. A–G. L. cephalus (Linnaeus, 1758), BSPG 2003 IV 72, 68, 74b, 65, 74a, 69, and 71 respectively, in dorsal (A–C, D1, F, G), anterior (D2), and ventral (E) views. All lapilli, except E, are represented as right ones (A–C, F, are mirrored). E is represented as left lapillus (mirrored). C, E display a lapilli pair. H–K. L. leuciscus (Linnaeus, 1758), BSPG 2003 IV 81, 82, 80, and 84 respectively, in dorsal (H1, K), anterior (H2), and ventral (I, J) views. H1 and K are represented as right lapilli (mirrored). H2, I, and J are represented as left lapilli. L–O. L. souffia Risso, 1826, BSPG 2003 IV 87b, 87a, 89, and 90 respectively, in dorsal (L1, N, O), anterior (L2), and ventral (M) views. L1, N, and O are represented as right lapilli (L is mirrored). L2 and M are represented as left lapilli (M is mirrored). L, M display a lapilli pair. P–R. L. idus (Linnaeus, 1758), BSPG 2003 IV 75, 76, and 77 respectively, in dorsal (P, R1), anterior (R2), and ventral (Q) views. P and R are represented as right lapilli. Q is represented as left lapillus. SEM−pictures (D, E, G–I, L, M, P–R), digital pictures (A–C, F, J, K, N, O).
