Where: Clark County, Nevada (36.4° N, 115.6° W: paleocoordinates 6.8° N, 40.8° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Bird Spring Group, Asselian (298.9 - 295.5 Ma)

• 21 m above 1262, gighest beds of limestone before a predominately sandy unit begins. The Permian part of the Lee Canyon section is 1,616 m thick. As first recognized by Barosh (1968), it has three lithologic units: a lower limestone sequence (238 m thick), a central sandstone sequence with some thin limestone beds (1,037 m thick), and an upper sandstone-limestone sequence (341 m thick). Lowest colonial rugose coral occurs in the lower part of the Zone of Pseudoschwagerina and slightly above the occurrence of Triticites creekensis.

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified limestone

Size class: macrofossils

Collected by E.C. Wilson, L. Walters in 1969, 1970, 1975; reposited in the LACM

Collection methods: peel or thin section,

• Author also notes abundant Omphalotrochus, cerioid and fasciculate rugose corals, some syringoporids.
