Excavations at the Late Archaic site of Tulan-52 (3450-2250 BC) in the Atacama Desert of Chile revealed what was initially considered to be a very early semi-sedentary settlement. New investigations into these earlier excavations, however, show evidence for structural and organisational characteristics that overlap with those found at the nearby ceremonial site of Tulan-54, dated to around two millennia later. The reinterpretation of Tulan-52 suggests that early monumentalism in the Puna de Atacama may reflect the emergence of social complexity among late hunter-gatherersa development that led to, rather than resulted from, the process of Neolithisation.
