Pleistocene Age Determinations from California and Oregon
Richards HG and Thurber DL. 1966. Pleistocene Age Determinations from California and Oregon. Science. 152(3725):1091-1092
Mollusks have been collected from Pleistocene marine deposits at Tomales Bay, California, and Cape Blanco, Oregon. Dating by the carbon-14 and thorium-230-uranium-234 methods suggests that the shells are at least 33,000 years old. The more probable age at the Tomales Bay locality is less than or equal to 50,000.
