Also known as USGS 648
Where: King County, Washington (47.4° N, 122.0° W: paleocoordinates 49.0° N, 106.9° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Raging River Formation, Lutetian to Lutetian (47.8 - 38.0 Ma)
• Formely included in Puget Group, but regarded as distinct due to lack of coal facies. Oldest sedimentary rocks in the Tiger Mountain-Taylor Mountain upland area. Probably lowermost collection of Raging River Formation. MacNeil (written communication) stated that there was little doubt this is a middle Eocene fauna. Probably equivalent to part of the McIntosh Formation of western Washington. Collection is from probably up to 1000 ft below the top of the formation.
• bed-level stratigraphic resolution
Environment/lithology: marine; siltstone and sandstone
Size class: macrofossils
Reposited in the USGS
Collection methods: quarrying,
• No repository for collection listed, but likely to be USNM.
