Abstract(s)

Notwithstanding their scarcity and uneven distribution, zooarchaeological and stable isotope data sets on the Early and Middle Neolithic (5500-3200 cal BC) in the region of Estremadura in Central Portugal strongly suggest that two succeeding stages in subsistence strategies took place: sheep and goat itinerant pastoralism (across large areas) and/or renewed focus on wild food sources (cervid hunting, harvesting marine and freshwater food) which replaced livestock farming within smaller areas and less specialised hunting practices. This economic shift seems to have coincided with two other dramatic changes: the 5.9 kyr cal BP climate event and the onset of megalithism. Possible correlations between these past cultural and palaeoenvironmental phenomena are herein preliminarily outlined.
