Derivation of the name : This species is dedicated to Dr. Clemens Mödden (Eltville, Germany ). He greatly supported the field studies in the Mainz Basin. Type locality : Wolfsheim, 20 km southwest of Mainz in the Mainz Basin (see Mödden et al. 2000 : fig. 1; here Fig. 2A ). Material .—90 lapilli, SMF PO 64053–54, BSPG 2003 XVIII 51–62. Dimensions and stratigraphic range .—See Tables 1 and 4 , and Fig. 32 . Diagnosis.— Lapilli with a distinct concavity of the posterior margin, a strongly curving medial margin, and a thickened middle portion. Description .—The general shape is rounded with a pointed posterior end. The strongly developed anteromedial and anterolateral edges, the distinctly pronounced mineralization area, and the distinct cranial umbo of the fossil lapilli resemble the Recent Tinca tinca ( Fig. 20 ). Remarks .—The single pharyngeal tooth ( Fig. 27L , length: 3 mm , width 1.59 mm) that was found in the locality Wolfsheim could be determined as cf. Palaeotinca (Madelaine Böhme, personal communication 2005). Presently, there are two Oligocene Palaeotinca species that both were found in sediments of late Oligocene age: P. macrura ( Agassiz, 1843 ) from some localities in Germany ( Gaudant 1988 , as Tarsichthys macrurus ) and Palaeotinca sp. from the Lower Freshwater Molasse in Switzerland and Haute−Savoie ( Gaudant et al. 2002 , as Tarsichthys sp. ). The pharyngeal tooth of our new species displays a mastication area that runs more or less oblique from the terminal hook to the proximal area. In contrast, P. macrura shows a more curving mastication area and also a more prominent incision beneath the terminal hook (see Gaudant et al. 2002 : fig. 2). P. moeddeni sp. nov. is presently the oldest worldwide record of a Palaeotinca species.
