Also known as Locality #156 (Moore, 1963); USGS 18928
Where: Lincoln County, Oregon (44.7° N, 124.1° W: paleocoordinates 44.5° N, 119.0° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Astoria Formation, Langhian (16.0 - 13.8 Ma)
• From silty shale, about 50-55 ft below basalt. From an unknown horizon. Astoria Formation has been used as a name for almost all of the marine middle Miocene sedimentary rocks of Washington and Oregon although these correlations are poorly constrained. The formation has been divided into three members: a lower sandstone, a shale, and an upper sandstone. These rocks form the northern limb of a syncline, the asis of which is exposed east of Astoria, and the syncline trends NE and plunges to the SW. The Astoria Formation is intermittently exposed; theya re faulted and exposures are interupted by volcanic rocks and slides. The maximum thickness of any exposure is 25 feet.
• bed-level stratigraphic resolution
Environment/lithology: coastal; poorly lithified, silty shale
Size class: macrofossils
Preservation: concretion, replaced with other
Reposited in the CAS, USNM
Collection methods: quarrying, surface (float),
• Collected by E.J. Moore, 1952. Collections reside in the Californian Academy of Sciences, the U.S. National Museum, and presumably the USGS.
