Also known as Vedder & Norris (1963) SN-16
Where: Ventura County, California (33.2° N, 119.5° W: paleocoordinates 33.2° N, 119.2° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Unnamed Formation, Quaternary (2.6 - 0.0 Ma)
• Dune sand and fossiliferous marine terrace deposits of Quaternary age. These overlie Eocene strata. Fossils come from seven well-developed wave-cut platforms at altitudes of 25 to 990 feet. Several submerged terraces are present on the shelf adjacent to the island., the lowest being 400 ft below sea-level. Presumably all the terrace platforms on San Nicholas Island were cut later than the middle Pleistocene diastrophism recognized elsewhere in southern California. Terrace platforms are covered with a variety of sediments of marine and non-marine origin and range in thickness from a few inches to many feet.
• bed-level stratigraphic resolution
Environment/lithology: coastal; pebbly, shelly/skeletal, conglomeratic, calcareous sandstone
Size class: macrofossils
Collection methods: quarrying,
• Collections made by Norris (1955). Earlier collections by Cooper (1894), and Howard (1955)
