This study focuses on the diet, environment and geographical origin of two populations buried in the Tablada de Lurín necropolis (2nd cent. BC - 2nd cent. AD; Lima, Peru) and seeks to test archaeological hypotheses based on material culture by contrasting the cultural evidence with biological data. Tablada is characterized by two distinct phases of occupation which evidence a clear rupture in burial patterns. Moreover, based on ceramic evidence and the lack of habitation sites in immediate proximity to the cemetery, it appears that both burial populations stem from a certain distance of the site (ca. 20 km) and that they were turned toward land rather than marine resources despite Tablada’s close proximity to the ocean. Forty-seven human individuals and eleven faunal remains from both occupational phases were sampled for isotopic analysis (carbon, nitrogen, sulphur and oxygen) of bone and dental collagen and apatite. Modern samples of autochthnous food staples were also tested in order to provide a baseline for comparison. Preliminary results show a clear preservation state difference between the remains of the two phases. The first phase individuals provide the best isotopic dataset and would show consumption of protein from marine resources. On the other hand, oxygen and carbon stable isotope results from the both phases highlight possible outsiders.Together with archaeological, anthropological and palaeoenvironmental data, this study seeks to understand both population's dietary habits and geographic origins and evaluate whether these shed any light on the cultural rupture revealed by the change in burial practices.
