Pechgraben sand pit (PM Nierstein collection) (Jurassic of Germany)

Where: Germany (50.0° N, 11.5° E: paleocoordinates 39.7° N, 12.0° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Bayreuth Formation, Hettangian (201.3 - 199.3 Ma)

• The Bayreuth Formation is considered temporally contiguous with the Psilonotenton Formation (lower Hettangian) and the overlying Angulatensandstein Formation (upper Hettangian); however, these formations cannot be confidently discerned at Pechgraben (Bloos et al. 2006).

• group of beds-level stratigraphic resolution

Environment/lithology: pond; lithified claystone

• The Pechgraben site likely preserves a low-energy freshwater environment (possibly an oxbow lake) that was surrounded by dense vegetation.

Size class: macrofossils

Preservation: mold/impression
