M3, Mammendorf Quarry (Oligocene of Germany)

Where: Germany (52.2° N, 11.4° E: paleocoordinates 51.7° N, 7.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Rupelian (33.9 - 28.1 Ma)

• Rocky-shore environments with boulder beds developed on the andesite in two Palaeogene transgressive cycles. The lower cycle includes M1-M3 and the upper cycle includes M4-M7. This stratigraphical level belongs to the nannoplankton zone NP 22 and corresponds to Rupel 1 sensu Spiegler (1965). The Septaria Clay in the M5 horizon represents probably the NP23 zone.

• bed-level stratigraphic resolution

Environment/lithology: foreshore; poorly lithified, glauconitic conglomerate

• Rocky shoreline
• Consists of boulder beds with glauconitic, green sands in the interstices.

Size class: macrofossils

Collection methods: bulk, chemical, peroxide, sieve

• Repository: Geological-Paleontological Collection (GPSL) of the Institute for Geophysics and Geology of the Leipzig University
