Coordinates: 39.2° North, 106.0° West (view map)
Paleocoordinates:4.1° North, 33.2° West
Basis of coordinate:based on nearby landmark
Geographic resolution:small collection
Time
Period:Permian Epoch:Cisuralian
Stage:Asselian 10 m.y. bin:Permian 1
Key time interval:Asselian
Age range of interval:298.90000 - 293.52000 m.y. ago
Stratigraphy
Formation:Maroon
Stratigraphy comments: 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)
Lithology and environment
Primary lithology: lithified "siliciclastic"
Lithology description: "many exposures of the 'red beds'" in the area "occasionally [contain] distinct plant impressions" (Elias 1953)
Environment:terrestrial indet. Tectonic setting:intermontane basin
Geology comments: Basins from block faulting associated with Ancestral Rocky Mountains
Taphonomy
Modes of preservation:body,adpression
Size of fossils:macrofossils
Collection methods and comments
Collection methods:selective quarrying,survey of museum collection
Reason for describing collection:taxonomic analysis
Collection method comments: 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
