DUPLICATE REF 3564 or 3565

Where: Cherry County, Nebraska (42.8° N, 100.8° W: paleocoordinates 43.1° N, 98.8° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Merritt Dam Member (Ash Hollow Formation), Clarendonian to Clarendonian (12.5 - 9.4 Ma)

• Skinner et al. 1984 mention that the Davis ash located near the base of the Merritt Dam member is between 9~11Ma. Smith et al. then U-Pb date the Grove Lake ash beds within the Merritt Dam member to ~6.4Ma, this suggests that deposition of the Merritt Dam began in the Claredonian and throughout the Hemphillian

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils

Reposited in the UCMP
