Fig. 1. Geological setting of the locality. A. Stratigraphic framework of the Rotliegend in the Saar Nahe Basin. B. Location of Saar−Nahe Basin (B1), geological map of the basin (B2), and location of the Remigiusberg quarry (B3). Lithostratigraphy follows Schindler (2007); isotopic ages after Burger et al. (1997), Königer et al. (2002), and Lippolt and Hess (1989); position of the Permo−Carboniferous boundary (299.0 ±0.8 Ma) is based on Ogg et al. (2008).
