USGS 21937-PC, Funeral Mountains (Carboniferous of the United States)

Also known as JFM64319C

Where: Inyo County, California (36.3° N, 116.5° W: paleocoordinates 7.2° S, 53.5° W)

When: t4 Member (Tin Mountain Formation), Osagean (352.0 - 343.0 Ma)

• Tin Mountain Limestone, about 175-190 ft above base, float virtually in place, about 700-1,000 ft north along strike from measured section across hill 2997, southeast end of Funeral Mountains.

Environment/lithology: gray, argillaceous, cherty/siliceous limestone

• Unit t4, which is 50 feet thick, forms a rubbly bench below a steeper slope or cliff. In the less resistant, lower part of the unit, thin limestone beds are interstratified with pale-red or pinkish-gray argillaceous beds. Reddish argillaceous material forms partings in the upper part. The limestone, which is medium gray or darker and weathers somewhat lighter gray is fine-to coarse-grained biocalcarenite that consists of fragmented mixed fossils. Unbroken fossils are conspicuous and varied. Elongate chert nodules, which almost coalesce in some beds, are abundant in the upper part of the unit.

Size classes: macrofossils, mesofossils

Preservation: original aragonite, original calcite, original phosphate, replaced with dolomite, replaced with silica
