Mammals recovered from archaeological investigations at Bighorn Cave represent the first mid-Holocene to late-Holocene faunal record from the Black Mountains of northwestern Arizona. With 2 exceptions, identified taxa have modern geographic distributions that include the location of the cave. A beaver (Castor canadensis) incisor from the lower shelter of the cave was possibly introduced into the deposit by humans. Microtus teeth from Bighorn Cave represent an extralocal record, and several explanations for their presence at Bighorn Cave are discussed. A new radiocarbon date presented here indicates that post-depositional mixing occurred in portions of the deposit.
