Also known as Nelson Ranch; South Park

Where: Park County, Colorado (39.2° N, 106.0° W: paleocoordinates 4.1° N, 33.2° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Maroon Formation, Asselian (298.9 - 295.5 Ma)

• thought by Scudder to be "Triassic," but more likely Permian according to Cockerell 1911 (Psyche) and Elias (1953); almost certainly in the Maroon Formation and very likely in the Wolfcampian upper Pony Spring Member based on Brill 1952 (see Fig. 1)

Environment/lithology: terrestrial; lithified siliciclastic sediments

Size class: macrofossils

Preservation: adpression

Collection methods: quarrying,

• found in a "shaft" owned by Robert A. Meier and first discovered by Arthur Lakes

•Elias (1953) unsuccessfuly attempted to relocate the site in 1944
