Antiquity and paleoenvironment of the Tamaulipan Biotic Province of southern Texas: the zooarchaeological perspective

The Tamaulipan Biotic Province (TBP) is an ecotonal community that has been characterized in the twentieth century as a mixture of plains, woodland, and desert-adapted mammalian taxa. Some authors have proposed that this heterogeneous mixture of animals is a result of human influence on the environment in the post-European contact period. Others have proposed that the characteristically disharmonious mixture of fauna has been present in south Texas since prehistory. By considering the presence of certain key taxa across the archaeological record of the area this thesis demonstrates that the fauna characteristic of the Tamaulipan Biotic Province can be followed back in time as far as the archaeological record allows. This work also provides complete lists of all vertebrate organisms present in the archaeological record of the area, organized by time period and also by archaeological site and citation.
