Carrizo Arroyo Unit 62 (Carboniferous of the United States)

Where: Valencia County, New Mexico (35.8° N, 107.1° W: paleocoordinates 0.6° N, 36.9° W)

• outcrop-level geographic resolution

When: Red Tanks Member (Madera Limestone Formation), Virgilian (303.7 - 298.9 Ma)

• Fusulinid information provided in other papers, but only generally cited here.

• group of beds-level stratigraphic resolution

Environment/lithology: poorly lithified, gray, green, red shale and gray, argillaceous limestone

• The lithology of unit 62 consists of dark gray, greenish gray, and reddish/maroon, moderately fissile shale beds containing concretionary gray to greenish gray argillaceous limestone, locally with dense but thin accumulations of molluscan shell fragments. Small flecks of organic matter and tiny carbonized plant fragments are also present within the shale intervals.

Size class: macrofossils

Reposited in the UNM
