Also known as NP 93

Where: Lane County, Oregon (44.0° N, 123.0° W)

• Paleocoordinates: 49.7° N, 103.8° W (Wright 2013)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Eugene Formation, Priabonian (38.0 - 33.9 Ma)

• Eugene Formation can be subdivided faunally: a lower unit correlating to the Keasey Fm, a middle unit correlating to the Gries Ranch Beds of WA, and a upper unit correlated with the Pittsburg Bluff Fm. Thickness of formation may be up to 15,000 feet, but probably around 5,000 feet. Most of the outcrops are scattered so it is difficult to estimate their relative stratigraphic placement

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified, tuffaceous, brown, gray, blue sandstone and tuffaceous, brown, gray, blue siltstone

Size class: macrofossils

Preservation: mold/impression, trace

Reposited in the CAS

Collection methods: quarrying,

• Collections held at University of Oregon, University of California, Californian Academy of Sciences (CAS), United States Geological Survey (USGS), and Stanford University (NP).
