The Bronze Age settlement of Sa Osa (Cabras), is one of the few Sardinian archaeological sites, which allows us to reconstruct a complete picture on the development of the exploitation of natural resources, agricultural technologies, breeding and capture of the early history of Sardinia. The time range is from the early stages of the Middle Bronze until Final Bronze age. The carpological remains found show a high degree of specialization in agriculture. The presence of animal remains found testifies the practice of breeding of some domestic animals like sheep, goats, pigs and cattle. Moreover, hunting, documented by the remains of deer and wild boar, played an important role. Among the so far studied osteological fragments mammals that inhabit woodlands and others who prefer plants of plains have been recognized. From these data a strong relationship between man and environment emerges. Although the early history of Sardinia, the role of the fishing seems limited to a secondary position than farming, in the nuragic site of Sa Osa the presence of a quite amount of remains of fish fauna and furnishings attributed to fishing equipment testify an economy based on the exploitation of fish resources.
