The Cupisnique culture (1500 BC-200 BC) is considered one of the most definitive and influential societies that existed in the Jequetepeque Valley of Peru. Their influence reached Cajamarca, Chavin, and the northern highlands of the area and included the continued cult of supernatural decapitators among the iconography. The Cupisnique archaeological sites include several settlements in Puemape on the coast, Limoncarro in the middle valley, Montegrande and Tembladera in the Upper Valley, and Kuntur Wasi in San Pablo.
Cupisnique was considered a pre-metallurgical culture, though evidence reveals the Cupisnique to be excellent goldsmiths. In later years, the Cupisnique and Chavin (900 BC- 200 BC) would merge to become one culture and then both would disappear. There is not much evidence to account for why this happened; however, there has been speculation that natural disasters might have been responsible.
