A marine invertebrate fauna of approximately 120 species has been recovered from lenses in a marine terrace sand near 250 feet in elevation on central Anacapa Island, California. Lower and presumably younger terraces on nearby islands have been considered to be Sangamonian in age. The assemblages from Anacapa are of rocky-shore aspect and thus resemble Upper Pleistocene faunas. However, they include a few forms otherwise known only from Lower Pleistocene and older rocks, for which rocky-shore facies are poorly known. Evidently the Anacapa assemblages are Early or at least pre-Sangamonian Pleistocene.
