The Fützen Bed represents the lowest oolitic interval of the Schinznach Formation. It consists of a thick-bedded, calcareous oolite (Paul 1971). The basal strata may contain chert nodules (Paul 1971; Hofmann et al. 2000). Macrofossils are rare in the Fützen Bed (Merki 1961; Rieser 1964; Paul 1971). Most of the ooids are recrystallised (Merki 1961) or dolomitised (Merki 1961; Rieser 1964). For discussion of the lithostratigraphic definition of the oolitic intervals see below.
