CATEGORY: site DEFINITION: A stratified, ancient quarry/workshop site just north of Lima, Peru -- an area of coastal lomas (areas of fog vegetation). Excavations revealed a lithicflakeindustry as early as the Late Pleistocene, dating between 9,000 to 11,000 years ago. Wood fragments helped define a Chivateros I period of c 9500-8000 BC. There is also a red zone with some flint chips which, by comparison of artifacts of the nearby Oquendo workshop date to pre-10,500 BC. The whole industry is characterized by burins and bifaces with the upper-level (Chinateros II) containing long, keeled, leaf-shaped projectile points which resemble points from both Lauricocha II and El Jobo. Dating has been aided by the deposition of both loess and salt crust layers which suggest alternating dryness and humidity and which can be synchronized with glacialactivity in the Northern Hemisphere.
