  abstract = {{T}his study applies an intra-skeletal sampling strategy to examine post-mortem alteration of archaeological human bone from west {M}exico, and to reconstruct ancient diet. {H}uman bone from the {C}hupicuaro culture ({M}exico, {P}reclassic period) constitutes an ideal material with which to examine subsistence strategies because the specific hydrothermal environment in which the population lived would have provided certain food components (hydrothermal waters and carbonates) with distinct signature in {C}a, {M}g, {F}, {L}i, {S}r, {M}n, {V} and {U} values. {F}our to ten samples were taken from the long bones of six skeletons. {B}one trace element content ({C}a, {P}, {F}, {M}n, {M}g, {N}a, {L}i, {V}, {Z}n, {R}b, {S}r, {B}a, {Y}, {L}a, {C}e, {N}d, {T}h, {U}) and bone alteration parameters (crystallinity, organic matter and secondary calcite content) were analysed at the intra-skeletal level. {S}table isotopic signatures (bone delta {C}-13 and delta {O}-18(carbonate)) and histological analyses were also performed on a single bone from each individual. {R}esults indicate that all of the skeletons were affected by post-mortem mineralogical, structural and geochemical transformations. {B}iological bone delta {C}-13 values seem preserved for most of the individuals but an increase in crystallinity accompanies depletion in bone delta {O}-18 values. {T}he combination of bone alteration parameters with bone elemental content shows that in this very specific context, a widespread dissolution-recrystallisation is unlikely. {O}f the hydrothermal tracers, {S}r, {F} and {L}i were of particular interest because their retention in living tissues is related to the amount ingested. {T}he intra-skeletal {L}i content does not reveal any pattern but {L}i depletion is not excluded. {I}n contrast, {S}r and {F} show a progressive intra-skeletal diagenetic enrichment likely due to gradual diffusion-adsorption processes. {T}he bones with the lowest concentrations in these elements are assumed to yield the best representative ante-mortem values. {T}he signal extracted from each skeleton, a very unusually high bone {S}r, {F} and {L}i content, is interpreted as reflecting the consumption of the local hydrothermal products, which are also enriched in these elements.},
