Stratigraphy
| Geological group: | Chinle | Formation: | Garita Creek | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Considered to be late Carnian (Adamanian) in age by the authors; however, recent radiometric dating suggests a Norian age for most or all of the Chinle. The Garita Creek Formation was formerly referred to as the "lower shale member of the Chinle Formation" | |||||
