Autobahnknoten Langenhorst C3-bed (Devonian of Germany)

Where: Nordrhein-Westfalen, Germany (51.3° N, 7.1° E: paleocoordinates 15.9° S, 5.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Hemberg Formation, Late/Upper Famennian (364.7 - 360.7 Ma)

• Strunian. Bed 71o. (Lane et al 2001): In 1930 W.E. SCHMIDT described all known crinoids from the German Lower Carboniferous. In that work he included specimens from the Etroeungt beds of Germany, which are now judged to be latest Devonian (Famennian: Strunian) in age (MICHELS 1986; AMLER 1993, 1995; AMLER et al. 1994),

• bed-level stratigraphic resolution

Environment/lithology: marine; shale and lime mudstone

• Section consists of sandstones, siltstones, shales, calcareous shales, some interbedded micrites, and oolitic micrites near the top (starting at about bed 74). Lowest micrite is at about bed 40. This bed is shale.

Size class: macrofossils
