ammonites
Denay L.S. (Devonian), Section V, Sample 69, 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: australis zone, Denay Limestone Formation, Eifelian (391.9 - 388.1 Ma)

• Johnson et. al. (1996) list this bed as "Section Prefix: VW, Sample number: 69, Nearest Foot: 200, Meters in section: 61.0". It is assumed that the nearest foot and meter measurements are referenced from the base of their Section V, as shown in Figures 2 and 3.

• bed-level stratigraphic resolution

Environment/lithology: basinal (); lithified, argillaceous mudstone and conglomerate

• thin, rhythmically interbedded, dark lime mudstone and marl (anoxic basinal facies)
