Bous-Volklingen Heilgenwalder Schichten (Carboniferous to of Germany)

Where: Saarland, Germany (49.3° N, 6.8° E: paleocoordinates 0.6° S, 15.8° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Heilgenwalder Schichten Formation, Westphalian D to Westphalian D (311.4 - 304.8 Ma)

• A schematic section (Text-Fig.2) is shown on p. 17. It contains information on bed thicknesses and general lithologies. The fossiliferous bed(s) directly underlie the Holz Conglomerate. The fossils are reported to have been collected from close to the boundary between Westphalian D and Stephanian A. Unclear which bed(s) the fossils were collected from, but section resolution is 10m high, so group of beds chosen as most likely description.

• group of beds-level stratigraphic resolution

Environment/lithology: paralic; gray, sandy shale and gray, green sandstone

• From symbol on section (Text fig. 2), lowest sandstone bed has nodules of some kind in it.

Size class: macrofossils

Preservation: cast, mold/impression, adpression

Collection methods: Collecting done between 1964 and 1973. Preservation described as "good".
