A Lithological log of Mätzenacker section with discontinuity surfaces (D15 and D16). Rudist-shell drawing from Matheron (1842). B South westward view from Vorderalp (Frümsner Alp) on the Hüser cliff along the south eastern anticline. The succession is composed of marlstones of the upper part of Drusberg Member (D2; Tierwis Formation pro parte) transforming into a succession of carbonates of the Schrattenkalk Formation and the Grünten Member (Garschella Formation pro parte). C Focus on the glauconitic Chopf Bed and its phosphatic ammonites in Alp Wis. D View of the irregularly bedded, bioclastic, mostly echinodermic limestones (unit S2?–S3) along the Brunnenberg road at Mätzenacker. E Focus on the cross-stratification inside the echinodermic limestones. F Contact between the Schrattenkalk unit S3 and the Grünten Member along the Brunnenberg road at Mätzenacker. G Focus on the bored firmground surface D14. H Thin section in the bioclastic limestone of the Grünten Member, characterized by its glauconite gains and abundant orbitolinids, Bergli section
