Also known as Mansfelder Revier; Burg-Oerner Revier; Kupferschiefer, Copper Shale

Where: Saxony Anhalt, Germany (51.6° N, 11.8° E: paleocoordinates 16.3° N, 23.4° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

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

• The Kupferschiefer is the basalmost unit of the Werra Formation, 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).

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; lithified, black, carbonaceous claystone

Size class: macrofossils

Preservation: permineralized

Collected in 1793; reposited in the MfN

Collection methods: quarrying,

• According to von Meyer (1856) one part of the Protorosaurus specimen was reposited in the "Königliche Mineraliensammlung zu Berlin" and the counterpart was in the collections of the "Gesellschaft der naturforschenden Freunde zu Berlin" at that time. Specimen now in collections of Museum fuer Naturkunde, Berlin
