Drewer D/C boundary section WJ, Famennian part (Devonian of Germany)

Where: Nordrhein-Westfalen, Germany (51.5° N, 8.4° E: paleocoordinates 16.3° S, 6.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Famennian (372.2 - 358.9 Ma)

• D/C boundary roughly between beds 205 and 206. Sequence includes Wocklum limestone, Hangenberg Black Shale, Hangenberg Sandstone, and Stockum Limestone.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; limestone and shale

• Section diagram includes shales, limestones, nodular limestones, and sandstone. It looks like the actual ammonoid occurrences are (mainly) in the limestones.
