Also known as State of Utah Loc. 42Gr001V, Utahraptor State Park
Where: Grand County, Utah (38.7° N, 109.7° W: paleocoordinates 37.1° N, 59.2° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Yellow Cat Member (Cedar Mountain Formation), Valanginian (139.8 - 132.9 Ma)
• stacked succession of 4 bonebeds below footprint level, and approx. 2 m above base of member in this area
•
•Detrital zircons from the quarry and adjacent, lateral equivalents provide a maximum depositional age of 125 Ma, indicating the horizon is no older than early Albian (Eberth et al., 2006), but more recent work indicates that the upper part of the Yellow Cat Member is Valanginian (Joeckel et al. 2020)
• group of beds-level stratigraphic resolution
Environment/lithology: crevasse splay; pebbly, intraclastic, silty, conglomeratic mudstone
•- four separate debris flows
Size classes: macrofossils, mesofossils
Collected by J. Kay, J. Jenson, L. Ottinger, B. Britt, J. Kirkland in 1968, 1994-1997
Collection methods: bulk, mechanical,
• entered as including 1400 specimens, but Britt et al. 2006 state that there are "4210 collected specimens"
