AbstractCogged stones are one of the few classes of artifacts which are limited in occurrence to the “middle” period of southern California's prehistory. They are stone discs, 6⅛ inches or less in diameter, characterized by grooves or indentations in the edge. On the basis of the nature of the latter and of the presence or absence of perforation they are described in four types. Some of the variations may have historical significance, but this cannot be proven with the data at hand. Few specimens have been excavated under controlled conditions. The distribution is virtually limited to the coastal drainage south of Ventura County and appears to center along the Santa Ana River Valley. According to the interpretation of coastal chronology employed, cogged stones were made during the period 6000-3500 B.C. Their use is unknown, but the absence of any pattern of wear and the conjunctions of certain of the specimens suggest that they served some ritual function.
