Zooarchaeology is the study of animal remains (bone, shell, antler, and other organic tissues) from archaeological sites, which can provide conservation biologists with data on human–environmental interactions with greater time depth than historical records. Such data are of interest because they can be used to study whether or not contemporary animal communities (in this case of freshwater mussels) have changed in terms of species composition or range as a result of human-induced changes to habitat, which is essential for determining a species’ conservation status and formulating actions to protect remaining populations. This study considers whether or not the taxonomic composition of the freshwater mussel community from the Leon River in central Texas differs between the late Holocene and today. Specifically, we analyzed two zooarchaeological assemblages and compared those results with recent surveys conducted within the Leon River. Three species proposed for listing under the Endangered Species Act are found in the zooarchaeological record, of which two are now extirpated from the river basin (Truncilla macrodon and Fusconaia mitchelli). The results of this study provide an example of how zooarchaeological data can be used to evaluate mussel community change through time and provide evidence of range curtailment for threatened mussel species.

The article presents a study which examines the human transport of mussel shell and the potential of zooarchaeological data. The study uses freshwater mussel shells from prehistoric sites in the Tombigbee River basin of Mississippi and Alabama. The study reveals that the archaeological data indicates that all or most of the shell recovered from specific sites came from waterways adjacent to the sites.

The article focuses on a study that presents a paleozoological perspective on the zoogeography of unionid in the upper Trinity River basin in central Texas. The study was undertaken through an analysis of faunal remains in three archaeological sites near the Clear Fork and West Fork of the river dating 2500 and 600 years ago and the use of historical and modern surveys. Results of the study show that at least one species was present during the late Holocene.
