Doelling's Bowl Bonebed (UMNH VP Loc. 1208) (Cretaceous to of the United States)

Also known as USGS

Where: Utah (38.7° N, 109.6° W: paleocoordinates 36.7° N, 58.9° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Yellow Cat Member (Cedar Mountain Formation), Late/Upper Berriasian to Late/Upper Berriasian (145.0 - 132.9 Ma)

• "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)

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; chert

• "mounds...may represent spring deposits such as those recognized at the Crystal Geyser Quarry"
• "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"

Size classes: macrofossils, mesofossils

• "ankylosaur, iguanodontid, and dromaeosaurid skeletal remains"
