Küchenberg quarry (Carboniferous to of Germany)

Where: Germany (51.5° N, 7.7° E: paleocoordinates 0.6° S, 14.0° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Ziegelschiefer Formation, Marsdenian to Marsdenian (318.1 - 314.6 Ma)

• The strata are slightly younger than those in the former brickyard quarry Voßacker at Fröndenberg (e.g., Schultka 1995). They may be of latest Namurian B age (Marsdenian: ammonoid zone R2: higher Ziegelschiefer Formation or Kaisberg Formation, early Bashkirian). Even an early Namurian C age cannot be excluded (Yeadonian: ammonoid zone G1: Sprockhövel Formation).

• group of beds-level stratigraphic resolution

Environment/lithology: mire or swamp; lithified, black, gray mudstone

• The Küchenberg section does not show any marine influence (Jenchen and Schultka 1993). The occurrence of the xiphosurid Bellinurus cf. truemani and trace fossils of Sinusites type indicate a nonmarine period. Schultka (1988) assumes a widespread freshwater area which was dammed up by marine transgressions in the hinterland. Since the swamps and bayous were closely adjacent to the Hagen-Vorhalle delta, they might have been more upstream in Küchenberg.
• Mudstone, dark gray to black.

Size class: macrofossils

Preservation: mold/impression
