Resumen

ALFONSO-DURRUTY, MARTA P; CALAS, ELISA  y  MORELLO, FLAVIA. Bioanthropological analisys of a Late Holocene human burial from Cabo Nose, Tierra del Fuego Chile. Magallania [online]. 2011, vol.39, n.1, pp.147-162. ISSN 0718-2244.  http://dx.doi.org/10.4067/S0718-22442011000100009.

The discovery, excavation and analysis of a burial in Cabo Nose, Tierra del Fuego, Chile, is presented. The burial was deposited in a shell midden composed mostly of mussels and Nacella sp., as well as some fish, birds and mammal bones (sea lion and guanaco). The remains corresponded to a young adult male dated to BP 980+/-40 (Late Holocene). The skeleton showed porotic hyperostosis, spina bifida occulta, and deformities in the tarsal bones of the left foot. These anomalies were most likely the result of a folate dietary deficiency caused by the ingestion of a diet that was rich in meats, but poor in leafy-green vegetables. This dietary deficiency affected the individual during the gestational period (spina bifida occulta) and childhood (porotic hyperostosis). It is also possible, however, that the congenital defects seen in this individual (spina bifida occulta and tarsal coalitions), were the result of a genetic condition. The isotopic analysis shows that this individual consumed a diet that was predominantly maritime, which is in agreement with the paleopathological evidence.

Palabras clave : human remains; Tierra del Fuego; late Holocene; spina bifida occulta; porotic hyperostosis.
