Coordinates: 33.7° North, 99.1° West (view map)
Paleocoordinates:0.9° South, 30.3° West (Wright 2013)
Basis of coordinate:estimated from map
Geographic resolution:small collection
Time
Period: Permian Epoch: Cisuralian
Stage: Artinskian - Kungurian 10 m.y. bin: Permian 2
Key time interval: Artinskian - Kungurian
Age range of interval: 290.1 - 274.4 m.y. ago
Stratigraphy
Geological group:Wichita Formation:Lueders Member:Maybelle limestone
Stratigraphic resolution:bed
Stratigraphy comments: 2 to 3 feet below the Aa2 submember of the Maybelle limestone
Lithology and environment
Primary lithology:grading lithified grainstone
Secondary lithology: lithified mudstone
Includes fossils?Y
Lithology description: 2 layers of graded grain-supported rock composed of vertebrate and invertebrate fossil debris, coprolites, and fecal pellets accompanied with pebbles and cobbles ("6 inch or more in largest diameter") of unfossiliferous impure lime mudstone and a matrix of sparry calcite, separated by about an inch of unfossiliferous mudstone
Environment:lagoonal/restricted shallow subtidal Tectonic setting:foreland basin
Geology comments: "composition [of the rocks] is interpreted as indicating deposition in relatively calm, shallow, near-shore, marine waters, possibly lagoonal or estuarine, and near the mouth of a freshwater stream"
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils,mesofossils,microfossils
Preservation of anatomical detail:variable
Abundance in sediment:abundant
Associated major elements:some
Disassociated major elements:many
Disassociated minor elements:many
Collection methods and comments
Collection excludes:all microfossils,some macrofossils
Collection methods:surface (in situ),acetic,field collection
Reason for describing collection:taxonomic analysis
Taxonomic list comments:Kissel (2002, Can. J. Earth Sci. 39(9)) suspects the single tooth-rowed captorhinid jaws (UCLA VP 1973-1977) to belong to Captorhinus magnus, but concludes that "the incomplete nature of the specimens prevents positive assignment."
