Hushpuckney Shale Member, La Platte, Sarpy County, NE (Schram, 1984, Location 4) (Carboniferous of the United States)

Where: Sarpy County County, Nebraska (41.1° N, 96.1° W: paleocoordinates 0.9° S, 27.6° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Hushpuckney Member (Swope Formation), Missourian (306.0 - 303.7 Ma)

• member-level stratigraphic resolution

Environment/lithology: offshore; fine-grained, black shale

• "black shales seem to represent a deep-water phase of a transgressive-regressive sequence" "if conodont biofacies reflect alternative controls such as substrate character or prey distribution, our data could be interpreted to indicate that the Late Paleozoic Midcontinent Seaway was never significantly deep."
• the black shales are "fine grained and sheety in form, with bedding slabs not particularly thin or paperlike"

Size class: macrofossils

Preservation: mold/impression, adpression, original carbon, replaced with pyrite

Collection methods: quarrying,
