Doelling's Bowl (Cretaceous of the United States)

Where: Utah (38.7° N, 109.6° W: paleocoordinates 37.1° N, 59.1° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Yellow Cat Member (Cedar Mountain Formation), Valanginian (139.8 - 132.9 Ma)

• "The Doelling's Bowl area preserves a particularly thick section of the Yellow Cat Member"

•Doelling's Bowl area falls under Lower Yellow Cat member (according to Kirkland et al. 2016). Joeckel et al. 2019 date this to the Valanginian

• 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

• Polacanthine ankylosaur tooth; Ankylosaur ossicles; Iguanodontid teeth; Titanosauromorph sauropod teeth; Crocodylian teeth; carnosaur theropod teeth
