Denay L.S. (Devonian), Section V, Sample 1020, N. Antelope Range, Nevada (Devonian of the United States)

Where: Eureka County, Nevada (39.2° N, 116.2° W: paleocoordinates 24.7° S, 55.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: ensensis zone, Denay Limestone Formation, Eifelian (391.9 - 388.1 Ma)

• Johnson et. al. (1996) list this bed as "Section Prefix: TA, Sample number: 1020, Nearest Foot: 1020, Meters in section: 310.9". It is assumed that the nearest foot and meter measurements are referenced from the base of their Secion V, as shown in Figures 2 and 3.

• bed-level stratigraphic resolution

Environment/lithology: offshore ramp; lithified, peloidal, sandy limestone

• description of the lithology of the upper part of the cycle is as follows: a ~60 meter-thick succession of dolomitized, ramp-margin peloid grainstone, containing up to 10% quartz sand; the portion of section v that contains bed 1020 is described as: thick bedded limestone
