"Feldschacht zu Kupfersuhl" (Permian of Germany)

Also known as Kupfer-Suhl; Kupferschiefer, Copper Shale

Where: Thuringia, Germany (50.9° N, 10.3° E: paleocoordinates 15.2° N, 22.7° E)

• coordinate based on nearby landmark

• hand sample-level geographic resolution

When: Kupferschiefer Member (Werra Formation), Wuchiapingian (259.9 - 254.2 Ma)

• The Kupferschiefer (T1) is the basalmost unit of the Werra Formation (Z1), the latter being the basalmost formation of the Zechstein Series (Uppermost Permian of Central Europe).

•Brauns et al. (2003) reported a date of 257.3±1.6 Ma (Late Permian/Lopingian: Wuchiapingian) for the Kupferschiefer based on a Re-Os geochronological study. The presence of the conodont Mesogondolella britannica in Kupferschiefer equivalents supports a middle Wuchiapingian age for the Protorosaurus-bearing levels (Legler et al. 2005, 2008).

• bed-level stratigraphic resolution

Environment/lithology: offshore; carbonaceous shale

• Deposition took place "below wave base in a stratified water body (Paul, 1986a)" (Becker & Bechstädt, 2006, Sedimentology 53, pp. 1083–1120)

•"Sedimentation rates during Kupferschiefer deposition were low (5 mm kyr); (Füchtbauer, 1968). The Kupferschiefer is thus interpreted as a condensed section, which formed during maximum flooding (Ross & Ross, 1995; Strohmenger et al., 1996a)." (Becker & Bechstädt, 2006).
