Pyramid Hill, west (Oligocene of the United States)

Where: Kern County, California (35.5° N, 118.8° W: paleocoordinates 35.2° N, 109.7° W)

• coordinate estimated from map

When: Vedder Sand Formation, Chattian (28.1 - 23.0 Ma)

• 75 feed below the top of the Veder zone. The sands of the Vedder zone lie about 1,400 feet below the top of the Temblor Formation. Kellogg (1932) states this is equivalent to the Vaqueros and thus Burdigalian (=Langhian) in age. This is almost certainly wrong. Age after Scheirer and Magoon 2007.

• formation-level stratigraphic resolution

Environment/lithology: marine; fine-grained, calcareous sandstone

• fine-grained calcareous sandstone nodule

Size class: macrofossils

Preservation: original phosphate
