Eckfeld Maar (NHMM collection) (Eocene of Germany)
Where: Eifel, Germany (50.1° N, 6.8° E: paleocoordinates 47.0° N, 3.0° 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)
• 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 class: macrofossils
Preservation: mold/impression, adpression, original carbon
Collection methods: quarrying, surface (in situ),
