Geography
| Country: | United States | State/province: | Arizona |
| Coordinates: | 35.1° North, 109.8° West (view map) | ||
| Paleocoordinates: | 10.7° North, 48.3° West | ||
| Basis of coordinate: | based on political unit |
Time
| Period: | Triassic | Epoch: | Late/Upper Triassic |
| Stage: | Norian | 10 m.y. bin: | Triassic 4 |
| Key time interval: | Norian | Other zone: | Adamanian |
| Age range of interval: | 227.00000 - 208.50000 m.y. ago |
Stratigraphy
| Formation: | Chinle | Member: | Sonsela | ||
| Stratigraphy comments: the quarry lies near the base of the Jim Camp Wash Beds (Sonsela Member, Chinle Formation) but its position relative to the "persistent red silcrete" approximating the Adamanian-Revueltian boundary has been difficult to establish. The vertebrate assemblage suggests that the site may be in the Adamanian land vertebrate holochronozone |
