Grube Messel Pit, grid square E9, 0.87-1.2 m below alpha (Eocene of Germany)

Where: Hessen, Germany (49.9° N, 8.8° E: paleocoordinates 46.9° N, 4.8° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Messel Formation, MP 11 (48.6 - 40.4 Ma)

• bed-level stratigraphic resolution

Environment/lithology: crater lake; lithified claystone

• "A drilling project conducted in 2001 showed that the former Lake Messel was a maar lake, which is a small deep lake that had its origin in an explosive volcanic eruption. The former lake basin had an original diameter of about 1.5 km, and a depth of about 300–400 m (Harms, 2002; Felder & Harms, 2004)."
• "The fossils are embedded in darkly coloured, finely laminated claystone sediments rich in organic substances (‘oil shale’), which were deposited in a meromictic lake (e.g. Goth, 1990)."

Size classes: macrofossils, mesofossils

Preservation: adpression, soft parts

Reposited in the SMF

Collection methods: quarrying
