Geography
Country:United States State/province:Nebraska County:Dawes
Coordinates: 42.7° North, 103.1° West (view map)
Paleocoordinates:43.5° North, 97.2° West
Basis of coordinate:estimated from map
Altitude:4157 feet
Geographic resolution:small collection
Time
10 m.y. bin:Cenozoic 4-5
Key time interval:early Early Arikareean - early Early Arikareean
Age range of interval:29.50000 - 18.50000 m.y. ago
Age estimate:28.87 to 28.25 Ma (paleomagnetic)
Stratigraphy
Geological group:Arikaree
Local section:Wildcat Ridge
Stratigraphy comments: Faunal correlation places the Wa.gner Quarry in the early early Arikareean NALMA, slightly older than the radioisotopicaJlly calibrated Gering Formation faunas and slightly younger than the "Brown Siltstone" lf's. This constrains the magnetostratigraphy to Chron 10n (28.25-28.87 Ma, Berggren et al. 1995). The section records the short reversal of C10n.1r.
