A phase in Ecuador's culture, dating c 500 BC - 500 AD that was discovered on La Plata Island (Manabi). Large pyramidal platform mounds, helmeted figurines, spouted jars, and incised pottery have been found and evidence of polychrome painting and metallurgy. Houses with saddle roofs (low, downward-curving roof ridges), pottery head/neck rests, figurines with one leg crossed over the other, Pan pipes graduated towards the center and ear plugs shaped like golf tees were unique to the culture - but they have parallels in southeast Asia. It has been suggested that they were introduced into Ecuador by voyagers from across the Pacific. Particularly elaborate anthropomorphic vessels give information on dress and ornamentation (nose discs and tusk-like pendants). Bahia was a well-developed socio-political and religious unit. The La Plata Island site was probably a ceremonial center as there is little evidence of daily living. Unfortunately, many sites have already been lost to modern development.
