DNA recovered from ancient coprolites can provide an important source of dietary and host information. In this study, ancient DNA techniques were applied to dog coprolites recovered from two pithouses at Bridge River, a complex hunter-gatherer village on the Fraser River, British Columbia. Dog mitochondrial DNA was targeted to assess the genetic relationship between the domestic dogs of Bridge River and other ancient and modern dog populations both locally and worldwide. Multiple Canis familiaris mitochondrial DNA sequences were recovered from the ancient remains, some of which matched sequences recovered from ancient dogs at other Pacific Northwest Interior Plateau sites. Mitochondrial sequences matching Oncorhynchus nerka were recovered from salmon bones within the canid coprolites, and from the coprolites themselves, indicating that domestic dogs at Bridge River had access to sockeye salmon. Whole genome analysis, followed by next-generation-sequencing on an Illumina MiSeq platform was also applied to investigate other dietary components, as well as the potential for obtaining host nuclear DNA from coprolites.
