Third Member of the Paradice member (Carboniferous of the United States)

Where: Cochise County, Arizona (31.9° N, 109.2° W: paleocoordinates 7.0° S, 47.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tennesseean zone, Paradise Formation, Carboniferous (358.9 - 298.9 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; shale and sandy limestone

• Third member of the Paradise formation.- These beds include 6 feet of shaly strata at the base, followed by gray sandy limestone 4 feet thick, which is overlain in turn by 10 feet of poorly exposed shaly beds, and capped by a 5-foot bed of black limestone

•bearing abundant but fragmentary

•mollusks. A fairly large

•fauna, obtained mostly from the

•lower limestone bed, is listed, but a

•much greater number of species is

•undoubtedly present whose identification

•awaits the finding of better

•specimens than the member ordinarily

•yields. The faunal list follows

Size classes: macrofossils, mesofossils

Preservation: original calcite

Collection methods: bulk, mechanical,
