Where: Fresno County, California (36.5° N, 120.5° W: paleocoordinates 35.6° N, 109.5° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Tumey Formation, Priabonian (38.0 - 33.9 Ma)
• The Tumey Sandstone occurs as a alrge lens in the shale of the Kreyenhagen Formation. The maximum thickness the Tumey Sandstone reaches is 800 ft. The Tumey Sandstone is overlain by the upper Kreyenhagen Shale and Temblor Formation. Has often been referred to as Eocene-Oligocene, but is early to middle Oligocene acccording to more recent correlation charts (e.g. Hickman, 1969). AGE: modified to Priabonian and "Tumey Formation" following EPICC stratigraphy revision [Hendy, 6/2020].
• bed-level stratigraphic resolution
Environment/lithology: offshore; lithified, fine-grained sandstone
Size class: macrofossils
Preservation: mold/impression
Collection methods: quarrying,
• Collection presumably reposited at Stanford University.
