Stratigraphy comments: Upper Campanian Kaiparowits Formation

Horizon—Upper portion of the middle unit of the Kaiparowits Formation, 17 m above an ash bed tentatively correlated to ash KBC-109, which has been dated to 75.51± 0.15 Ma
Lithology and environment
Primary lithology: not reported
Includes fossils?Y
Environment:fluvial indet.
Geology comments: The Kaiparowits Formation is a non-marine sequence that was deposited upon a low-relief inland alluvial plain environment (Roberts et al. 2005). Radiometric dating demonstrates that it spans 76.1–74 Ma and thus dates to the Judithian North American Land Mammal Age (Cifelli et al. 2004; Roberts et al. 2005). It is contemporaneous with a number of well-studied late Campanian terrestrial vertebrate faunas of western North America (Gates et al. 2010).
