Also known as UO 2554
Where: Lane County, Oregon (44.1° N, 123.1° W: paleocoordinates 44.4° N, 110.8° W)
• 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).
