Stratigraphy
| Geological group: | Dakota | Formation: | Cedar Mountain | Member: | Buckhorn Conglomerate |
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: "A thick carbonate paleosol locally overlies the Buckhorn and a similar paleosol has been used to define the base of the Cretaceous elsewhere....Well-developed paleosols may occur at a number of stratigraphic positions within the Cedar Mountain Formation...the recent discovery of a possible ankylosaur...suggests a Cretaceous age."
