    Description: Die Rehbergschichten treten im linksrheinischen Buntsandstein zwischen Trifels- und Karlstalschichten auf. Es ist ein Wechsel von Felsbänken und Dünnschichten, wobei die Felsbänke die petrographischen Merkmale der Trifelsschichten, die Dünnschichten die sedimentologischen Merkmale der Unteren Karlstalschichten enthalten. Die Untergrenze der Rehbergschichten bildet die tiefste Lage von Dünnschichten (Scheidter Niveau). Die Obergrenze der Rehbergschichten bildet die stratigraphisch höchste Felsbank mit den petrographischen Merkmalen der Trifelsschichten oder des smi. Stratigraphisch markante Felsbänke bestehen innerhalb der Rehbergschichten nicht, eine stratigraphische und kartographische Unterteilung der Rehbergschichten ist nicht möglich. Genetisch werden die Rehbergschichten als Wechsel zwischen äolisch und fluviatil sedimentierten Schichten verstanden. Die Rehbergschichten tragen in der Landschaft weite Verebnungsflächen, wobei Verebnungen und Hangverflachungen in verschiedenen Niveaus übereinander vorkommen.
    Description: Abstract: The Rehberg sandstone is found in the Southwest German and Alsatian Buntsandstein between Trifels and Karlstal sandstones. Banquettes and lamelliform layers relieve one another, the banquettes containing the petrographic characteristics of the Tifels sandstone and the fine bedded layers the sedimentological characteristics of the lower Karlstal layers. The lower boundary of the Rehberg sandstone forms the lowest deposit of the fine bedded layers (Scheidter Niveau). The upper boundary of the Rehberg sandstone forms the stratigraphically highest banquette with the petrographic characteristics of the Trifels sandstone or the sny. Within the Rehberg sandstone stratigraphically noticeable banquettes do not exist. A Stratigraphie and cartographic division of the Rehberg sandstone is not possible. As far as genesis is concerned, the Rehberg sandstone are regarded as an alternation of eolian and fluviatile sedimented layers. The morphological structure of the landscape formed by the Rehberg sandstone shows wide peneplanations which occur at different levels.

    Description: Investigations on the systematic position of the foraminifer generally refered to as Hastigerina demens known from the Aquitanian of the Mayence basin have shown, that a new classification has to be made. Based on the shown protoforamina the species has to be considered as belonging to the family Polystomellidae EIMER & FICKERT, 1899. The aberrant test of the species which above all appears in the evolute arrangement of the chambers, has induced the author to place the species in a new genus Nonionoides n. gen. For N. demens a benthonic way of life has to be assumed. Therefore no autochthon planctonic living foraminifers are known from the Hydrobia beds and Corbicula beds of the Mainz basin.
