Reconstruction of Oligocene and Neogene freshwater fish faunas-an actualistic study on cypriniform otoliths Author Schulz-Mirbach, Tanja Author Reichenbacher, Bettina text Acta Palaeontologica Polonica 2006 51 2 283 304 journal article 10.5281/zenodo.13643922 1732-2421 13643922 Carassius cf. gibelio ( Bloch, 1782 ) Fig. 10D . Material and dimensions .—See Table 2 . Description .—The general shape can be best described as an irregular rhombohedron. The edges are pronounced; only the posteromedial edge may be absent or weakly developed. The lapilli of C. cf. carassius ( Fig. 10A, B, F 1 ) are especially well characterised because of their rhomboheric symmetry and the distinct concavity in the middle of the medial margin.
