High Quality Content by WIKIPEDIA articles! The Norte Chico civilization ( dated from 9210 BCE -1800 BCE, also Caral or Caral-Supe civilization) was a complex pre-Columbian society that included as many as 30 major population centers in what is now the Norte Chico region of north-central coastal Peru. It is the oldest known civilization in the Americas and one of the six sites where civilization separately originated in the ancient world. It flourished between the 30th century BC and the 18th century BC. The alternative name, Caral-Supe, is derived from the Sacred City of Caral in the Supe Valley, a large and well-studied Norte Chico site. Complex society in Norte Chico arose a millennium after Sumer in Mesopotamia, was contemporaneous with the Egyptian pyramids, and predated the Mesoamerican Olmec by nearly two millennia.
