Piki Mach'ay yielded some of the oldest plant remains in Peru, including an 11,000-year-old bottle gourd. Strata from later periods at the site revealed fishtail point arrows, manos, and metates. Plant remains indicate that, before 3,000 years BCE, amaranth, cotton, gourds, lúcuma, quinoa, and squash were cultivated in the Ayacucho Basin before 3,000 years BCE. By 4,000 years BCE corn (Zea mays) and common beans were grown. Chili remains date from 5,500 to 4,300 years BCE. The large amounts of guinea pig bones suggest possible domestication, and llamas may have been domesticated by 4,300 to 2,800 years BCE. == See also ==
