Also known as Pysht area
Where: Clallam County, Washington (48.2° N, 122.1° W: paleocoordinates 47.9° N, 113.2° W)
• coordinate based on political unit
• outcrop-level geographic resolution
When: Clallam Formation, Chattian (28.1 - 23.0 Ma)
• SPECIFIC STRATIGRAPHY: From three 1-m thick beds in an interval between 191 and 207 m above the base of the formation. GENERAL STRATIGRAPHY: The Clallam Formation is a predominantly marine sandstone with minor conglomerate and siltstone exposed along the Strait of Juan de Fuca in northwestern Washington. Marine molluscs occur throughout the 600 to 800 m thick formation but are especially abundant in the lowermost 240 m. Pillarian Stage age, a provincial time stratigraphic unit of late early Miocene age. Revised to Chattian following more recent work [Hendy, 7/2016].
• bed-level stratigraphic resolution
Environment/lithology: offshore; lithified sandstone
Size class: macrofossils
Preservation: mold/impression
Reposited in the USGS
Collection methods: surface (float), surface (in situ),
