Also known as 42Gr190V, Nedcolbertia Site
Where: Grand County, Utah (38.8° N, 109.6° W: paleocoordinates 37.2° N, 59.1° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Yellow Cat Member (Cedar Mountain Formation), Valanginian (139.8 - 132.9 Ma)
• base of upper part of member
•
•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)
• bed-level stratigraphic resolution
Environment/lithology: lacustrine; green, red, sandy claystone
Size classes: macrofossils, mesofossils
Collection methods: quarrying, mechanical,
