Genus Alburnoides Jeitteles, 1861

aff. Alburnoides sp.

Fig. 23 .

Illerkirchberg and Le Locle. Instead, teeth belong to Palaeocarassius sp. and Palaeoleuciscus sp. in Illerkirchberg ( Gaudant et al. 2002; Reichenbacher et al. 2004a) and to species of Palaeocarassius , Palaeoleuciscus , and Rutilus vel Scardinius in Le Locle ( Gaudant et al. 2002; Madelaine Böhme, personal communication 2004).

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

Description.—The lapilli are characterised by their strongly extended anteromedial edge, which is displaced towards the cranium, the minor anterolateral edge, and the shallow incision. Similar to lapilli of Alburnoides bipunctatus ( Fig. 6 ), the medial margin is straight to slightly concave and runs more or less parallel to the maximal length of the lapillus.
