AbstractExcavations at Site PV62-63 (Cerrillos) uncovered a refuse accumulation several meters deep with two major stratigraphic units, the earlier termed the Cerrillos phase, the later termed the Isla phase. Cerrillos ceramics are of a style new to the Ica sequence and the earliest known in the valley; they represent an early development in the Paracas style, but also share various specific traits with Chavinoid ceramic styles in other areas. Ceramics of the Isla phase represent a local development out of Cerrillos but with many of the Chavinoid traits lacking. The Isla ceramic style had been previously recognized as the earliest known Paracas phase, although no refuse excavations had been made. Isla refuse is associated with a series of superimposed adobe structures, representing terraced habitations arranged in a complex apartment-house-like dwelling unit. The refuse of both stratigraphic units indicates very heavy dependence on agricultural produce, beans and a primitive type of maize being the staples. Various other artifact types were recovered, the Cerrillos textiles also showing similarities with early techniques in other areas.
