Eckfeld Maar (NHMN 1990 collection) (Eocene of Germany)

Where: Eifel, Germany (50.1° N, 6.8° E: paleocoordinates 47.0° N, 2.9° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: MP 13 zone, Eifel Formation, MP 13 (48.6 - 40.4 Ma)

• The Eifel is the German part of the outcropping Variscan Basement west of the river Rhine and nort of the river Mosel.

•"MP 13... recently dated at 44.3 +/- 0.4 million years BP (Mertz et al. 2000)" (Franzen 2004)

•Insects come mostly from teo horizons near marker horizon HT & KaLH

• bed-level stratigraphic resolution

Environment/lithology: crater lake; siltstone and shale

• "a small freshwater [crater] lake a few hundred meters in diameter" (Franzen 2004)
• ...laminitic "oilshales" and siltstones... with frequent turbiditic intercalations... plant macrofossils are ... distributed throughout the sequence under investigation. ... coarse and robust plant debris such as wood fragments and large fruits/seeds is concentrated in the turbiditic layers. (Wilde and Frankenhauser 1998).

Size classes: macrofossils, mesofossils

Preservation: mold/impression, adpression, original carbon

Collected in 1990

Collection methods: quarrying, surface (in situ),
