Rott (Kastenholz Bonn coll.) (Oligocene of Germany)

Where: Nordrhein-Westfalen, Germany (50.7° N, 7.3° E: paleocoordinates 50.6° N, 4.3° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: MP 30 (28.4 - 23.0 Ma)

• "MP30"

Environment/lithology: lacustrine - large; lithified, fine-grained, brown lignite

• According to the reconstruction of the sedimentation history. the limnic sediments of the Rott Fonnation were deposited in a single, relatively small and shallow lake (Mors, 1995). This lake was at least 3 km in diameter, and was encircled by a large accretion zone, which passed into an alluvial forest. Many small rivulets are expected to have flown into the Rott Lake, but no large river could be evidenced (MOn, 1995). The estimated mean aunual temperature (MAT) in this area at the accumulation time of lake sediments was17.5±1.2°C, based on the leaf margin analysis (Winterscheid, 2006).
• "fine layered brown coal" also called "lignites": figure of specimen indicates complete lithification

Size classes: macrofossils, mesofossils

Preservation: adpression
