The following chapters of this book (Chapters 5-10) summarize and illustrate the diverse suite of analytical techniques used to develop paleoenvironmental reconstructions from paleozoological assemblages. Though our discussion of those techniques draws upon a variety of assemblages from different times and places around the world, we illustrate our analyses using the same faunal assemblages as often as possible. We hope this commonality will allow the reader to focus on variability in the analytical techniques rather than on variability in the faunal assemblages.The faunas we routinely turn to include the late Quaternary micromammals (rodents and assorted insectivores <0.15 kg adult body mass) and macromammals (mammals >0.75 kg adult body mass) from Boomplaas Cave in South Africa. These faunas are zooarchaeological in the sense that they were recovered from deposits that include abundant archaeological material, though as we outline below this does not mean that humans accumulated all of the faunal remains. We also consider the late Quaternary small mammals (rodents and lagomorphs) from Homestead Cave in Utah (western United States). The Homestead Cave faunas are paleontological; human occupation of the site was limited, there are very few artifacts, and there is no evidence to implicate people in the accumulation of the faunal remains. We selected these sites for several reasons. First, both provide stratified sequences that span long periods of time and encompass substantial environmental changes (based on associated non-faunal data). Second, they provide sufficiently large samples to reasonably illustrate
