Domestic dog associated with human remains at Rancho La Brea by Richard L. Reynolds. Bull. Southern California Acad. Sci., 84(2):76-85, 1985. In 1914, human remains were discovered in an asphalt deposit at Rancho La Brea, California. The skull and mandible of a small domestic dog (Canis familiaris) together with a number of shell and stone artifacts were found associated with the human skeleton and all appear to date at 9000 ± 80 years before present. Re-examination of all available data indicates this occurrence is a secondary burial (reburial) rather than a primary interment, accidental entrapment, or the concealment of a homicide victim, as previously suggested.
