LACMIP 1255, Lee Canyon (Permian of the United States)

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 Formation, Asselian (298.9 - 295.5 Ma)

• 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

• paleogeography is interpreted as shallow water near the east side of the mouth of a south-opening coastal sea, bordered on the east by the continent and on the west by the Antler Highland; deposited in clear, shallow, warm marine water of normal salinity and with full access to the open sea
• Limestone, medium to fine grained, dark gray weathers medium gray, beds 1-3 feet thick, no chert, series of steps, partly covered, attitude 230, 24 degrees NE.

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 large scaphopods, abundant very large fasciculate rugose corals, syringgoporid corals, fusulinids.
