The lowermost macrofossil-rich stratum of the Kienberg Member is often rich in Coenothyris vulgaris and is here newly named Saalhof Bed. These brachiopod shells are usually dolomitised. At the type locality it consists of two strata, of which the lower one contains brachiopod shells only in its middle part (Fig. 10). The Saalhof Bed does not occur in whole northern Switzerland. Whether it was eroded briefly after deposition as supposed by Merki (1961) or it was not deposited areawide remains unclear.
