Where: Curry County, Oregon (42.6° N, 124.0° W: paleocoordinates 46.6° N, 105.1° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: P8 foram zone, Tenmile Member (Lookingglass Formation), Ypresian (56.0 - 47.8 Ma)

• Originally "middle Eocene." Recent studies by Prothero (2009) on the magnetic stratigraphy, combined with the occurrence of P8 planktonic foraminifera Zone and NP12/CP10 nannofossil Zone, constrain the age estimates of the formations within the Umpqua Group to 52.3-47 Ma, with the early Eocene Lookingglass Formation assigned an age of 49.8-50.8 Ma.
