Taoshigo (Carboniferous of China)

Where: China (43.3° N, 88.9° E: paleocoordinates 36.4° N, 78.9° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Qijiagou Formation, Moscovian (315.2 - 307.0 Ma)

• most crinoids are from a single debris flow

• bed-level stratigraphic resolution

Environment/lithology: submarine fan; lithified, coarse-grained, volcaniclastic, conglomeratic sandstone

• "deposited by sediment gravity flows in relatively deep marine conditions... swept off of an adjacent carbonate mound" on "proximal deltaic deposits"
• "volcaniclastic [coarse] conglomeratic sandstones" with "porphyritic andesite pebbles 2-20 cm across" plus "limestone pebbles" that "commonly are dolomitic, contain abundant fragments of bryozoans, and most show signs of early cementation"

Size class: macrofossils

Collected in 1993; reposited in the USNM
