Paleocoordinates:0.5° North, 26.3° West
Basis of coordinate:stated in text
Geographic resolution:outcrop
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
Geological group:Council Grove Formation:Eskridge
Stratigraphic resolution:bed
Stratigraphy comments: Within the lower P2 paleosol. This unit lies well above the first occurrence of the Permian index fossil Streptognathodus isolatus in the Bennet Shale Member of the Red Eagle Limestone but is below the first occurrence of the Sakmarian indicator species Sweetognathus merrilli in the Eiss Limestone member of the Bader Limestone, constraining the age to the Asselian (298.9–295.0 Ma).
