This paper examines the application of mammalian taxonomic diversity measures in the analysis of human subsistence. Employing qualitative and quantitative taphonomic analyses on archaeofaunas recovered from a sheltered Fremont site in Utah, numerous small- and medium-sized animal bones (especially Leporidae) are identified as nonhuman accumulations. Measures of taxonomic diversity for the shelter's entire assemblage suggest that the inhabitants practiced a generalized, broad-spectrum subsistence strategy. Omitting the nonhuman accumulations and calculating similar measures on bones interpreted as human refuse produce a different portrait of subsistence practices. Using this investigation as a case study, mammalian faunal assemblages from six additional Fremont assemblages are examined to further demonstrate that subsistence inferences based on diversity measures should be approached with caution. We demonstrate that measures of taxonomic diversity are valuable tools but should be used in concert with analyses of taphonomic agents. Furthermore, rather than employing only those bones identified to species, we emphasize that specimens identified to taxonomic genera may offer adequate resolution in examining prehistoric diet breadth.
