sentences:  Current estimates put the beginning of the San Luis Rey Complex at around AD 500–1000.The primary traits that distinguish this complex from the locally preceding San Dieguito, La Jolla, and Pauma complexes are the presence of small projectile points (indicative of use of the bow and arrow), pottery, and the practice of cremation.Other San Luis Rey Complex lithic tools include mortars and metates (both bedrock and portable), pestles and manos, flaked edge tools (scrapers and knives), hammers, drills, steatite arrow straighteners, pendants, beads, and quartz crystals.
