Geography
Country:United States State/province:Utah
Coordinates: 38.7° North, 109.6° West (view map)
Paleocoordinates:34.4° North, 44.1° West (Wright 2013)
Basis of coordinate:estimated from map
Geographic resolution:outcrop
Time
Period: Cretaceous Epoch: Early Cretaceous
Stage: Berriasian - Valanginian 10 m.y. bin: Cretaceous 1
Key time interval: Late Berriasian - Valanginian
Age range of interval: 139.1 - 132.6 m.y. ago
Stratigraphy
Geological group:Dakota Formation:Cedar Mountain Member:Yellow Cat
Stratigraphic resolution:group of beds
Stratigraphy comments: "The Doelling's Bowl area preserves a particularly thick section of the Yellow Cat Member" ""ankylosaur, iguanodontid, and dromaeosaurid skeletal remains that are all compatible with an Early Cretaceous age"; below marker calcrete and above the "chert interval"

Recent work indicates that the lower part of the Yellow Cat Member is late Berriasian-Valanginian (Joeckel et al. 2020)
Lithology and environment
Primary lithology:wavy/flaser/lenticular bedding chert
Lithology description: "The basal chert bed at Doelling's Bowl...displays a wavy laminated structure and preserves silicified roots. Additionally, numerous large chert mounds nearly a meter thick and several meters wide are present at the site"
Environment:terrestrial indet.
Geology comments: "mounds...may represent spring deposits such as those recognized at the Crystal Geyser Quarry"
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils,mesofossils
Collection methods and comments
Collection methods:field collection
Reason for describing collection:general faunal/floral analysis
