p.134: Küssaburg Member (Würtenberger & Würtenberger 1866) ; Member of the Villigen Formation Würtenberger & Würtenberger (1866. p. 30) introduced the name Küssaburg Member (Küssaburg-Schichten) for a succession of bedded, micritic limestones between the Hornbuck Member below and the Wangental Member above. The name is derived from the ruin of Küssaburg southeast of the village of Bechtersbohl in the lower Klettgau valley (southern Germany). LK 1050 Zurzach. There are only insignificant outcrops of the member below the Küssaburg ruin, but a continuous section could be measured in 1962 in the gully called Steiggraben 2 km southwest ofthe village of Geisslingen in the German lower Klettgau valley. This is section RG 74 at coordinates 670.550/273.020 which is less than 2 km east of Küssaburg ruin. The section is represented in Gygi (1991. Fig. 4) and can serve as type section of the Küssaburg Member. The thickness of the Küssaburg Member in the Steiggraben gullv is 32.5 m. Below is the glauconitic Crenularis Member with a sponge bioherm at the base. The top of the Küssaburg Member in the type section RG 74 is marked by the glauconitic bed 46 that belongs to the Knollen Bed. Ammonites are rare in the Küssaburg Member. Gygi & Persoz (1986. table 3 and Pl. 1) mentioned Taramelliceras (Metahaploceras) litocerum (Oppel) ofthe Hauffianum Subchron. Gygi (1969, p. 98 and Fig. 5) claimed to have found fragments of Subnebrodites in the Küssaburg Member. This is based on an error. There is a transition between the Küssaburg Member and the coeval Wangen Member of Canton Aargau. The boundary in figure 1 is drawn arbitrarily along the Rhine river that is the boundary between Switzerland and Germany north of Mellikon in Canton Aargau.
