Scar House Gill, Upper 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, Cockhill Marine Band Formation, Arnsbergian (326.4 - 318.1 Ma)

• "the complete fossiliferous horizon is more suitably termed the 'Cockhill Marine Band'...the term 'Cockhill Limestone' is retained but restricted to the band of fossiliferous limestone or limestone nodules where present."

• member-level stratigraphic resolution

Environment/lithology: marine; lithified, concretionary, shelly/skeletal, calcareous, carbonaceous mudstone and wackestone

• 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).
• fossiliferous black shale...carbonaceous shale...medium grained sandstone...orange mud...gingerbread crinoidal sandstone...nodular limestone in black calcareous mudstone
