Lithology and environment
| Primary lithology: | planar lamination lithified carbonaceous claystone | ||
| Lithology description: "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)." | |||
| Environment: | crater lake | Tectonic setting: | volcanic basin |
| Geology comments: "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)." | |||
