Where: Clark County, Nevada (36.5° N, 115.6° W: paleocoordinates 10.2° N, 39.1° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Bird Spring Group, Artinskian (290.1 - 279.3 Ma)

• 264 m above 1268. 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). The upper sandy limestone sequence has a primitive Parafusulina sp. at about 150 m above the contact with the sandy sequence and therefore indicates the Zone of Parafusulina and the Leonardian Series. This is strengthened by the occurrence of Schwagerina gumbeli and S. crassitectoria in several overlying beds Top of section maked by fault.
