• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Reunion Creek Beds Formation (Arikaree Group), Harrisonian (24.8 - 20.4 Ma)

• "early late Arikareean" (= Harrisonian)

•"lenses" within "14.5 m" section

•"lateral equivalent of the lower Harrison Formation"

• member-level stratigraphic resolution

Environment/lithology: fluvial; conglomerate and gray sandstone

• "lenses of fluvial, poorly sorted, fine-pebble gravel (predominatly granite epiclasts) deposited within 14.5 of very fine, gray, crossbedded to massive sandstone"

Size class: mesofossils

Reposited in the UNSM

Collection methods: bulk, sieve,

• rock censused consists of "concentrate," not the original sediment
