Also known as USGS D499

Where: Eureka County, Nevada (40.5° N, 116.2° W: paleocoordinates 41.8° N, 72.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Newark Canyon Formation, Albian (113.0 - 100.5 Ma)

• Fiori et al. 2020: our new U-Pb ages indicate that deposition of the basal member of the NCF (Knc1) occurred no earlier than ca. 114 Ma, deposition of member Knc3 occurred no earlier than ca. 106 Ma, Knc4 was being deposited at ca. 103 Ma, and depo- sition of the youngest member (Knc5) occurred no earlier than ca. 99 Ma. Therefore, deposition spanned from possibly as early as the late Aptian until at least the early Cenomanian.
