Old Quarry, Wath (iii), Nidderdale (Carboniferous of the United Kingdom)

Where: England, United Kingdom (54.2° N, 1.9° W: paleocoordinates 0.9° S, 6.2° E)

• small collection-level geographic resolution

When: E2 zone, upper middle (iii) division Member (Colsterdale Marine Beds Formation), Arnsbergian (327.0 - 323.7 Ma)

• Bisat (1914) referred to the marine strata as the Colsterdale Marine Beds, a term retained in this account.

• member-level stratigraphic resolution

Environment/lithology: marine; lithified, pyritic, gray, silty, carbonaceous lime mudstone

• Paleoenvironment could possibly be paralic or deltaic. There are a lot of preserved wood fragments and other plant remains. It was definitely near-shore, also definitely marine (according to the authors).
• predominantly gray and black shales intercalated with a thin limestone which locally degenerates into a band of calcareous nodules. (iii) hard, dark grey calcite mudstone. degenerates into a line of calcareous nodules only a few inches thick in once instance. generally banded due to silty layers. in thin section, streaked with a brown, oily pigment. scattered grains of quartz, shell fragments, and pyrite.

Preservation: replaced with pyrite
