La utilización de recursos malacológicos en el período Arcaico: una perspectiva del sitio arqueológico Cruz Verde, Valle Chicama.

Excavations in 2016 and 2017 at the Cruz Verde site, located in the coastal area of the Chicama Valley, revealed a stratified record of pre-ceramic mound-building practices. These activities, indicated from this archaeological data, repeated around the Middle Archaic period with abundant disposed natural remains in the fill of the mound. In this article, results of malacological analyses of archaeological remains, from this mound and other later occupation in the Late Archaic period of the Cruz Verde, are presented to examine chronological change of mollusc exploitation in the Archaic period. The taxonomical abundance analysis, biometric analysis and calculation of Diversity index of species indicate that a change of ecological environment has occurred in the CV-Ic phase (4000-3800 cal BC), the second phase of the Middle Archaic occupation, and a change of exploitation strategy in the CV-Id phase (2800 cal BC), the Late Archaic occupation of the Cruz Verde. In conclusion, indicated by a perspective from malacology, this study demonstrates that the marine resources use and human adaptation to ecological surroundings dynamically had changed through the Middle and Late Archaic periods in contrast with continuity of the mound-building tradition in the Chicama valley.
