What can the interactions of ancient mammals and their environments tell us about the present – and the future?
Classic palaeontology has focused on the study of fossils and the reconstruction of lineages of extinct species. But as diverse fossils of animals and plants were unearthed and catalogued, it became possible to reconstruct more elaborate ecosystems, tying together plants, animals, and geology. By the second half of the twentieth century, this effort gave birth to the field of palaeoecology: the study of the interactions between organisms and their environments across geologic timescales.
In Mammalian Paleoecology, Felisa Smith broadly considers extinct mammals in an ecological context. Arguing that the past has much to teach us, and that mammals, which display an impressive array of diverse life history and ecological characteristics, are the ideal organism through which to view the fossil record, Smith
- reviews the history, major fossil-hunting figures, and fundamental principles of palaeoecology, including stratigraphy, dating, and taphonomy
- discusses the importance of mammal body size, how to estimate size, and what size and shape reveal about long-dead organisms
- explains the structure, function, and utility of different types of mammal teeth
- highlights other important methods and proxies used in modern palaeoecology, including stable isotopes, ancient DNA, owl pellets, Sporormiella fungal spores, and palaeomidden analyses
- assesses nontraditional fossils
- presents readers with several case studies that describe how the fossil record can help inform the scientific discussion on anthropogenic climate change
Mammalian Paleoecology is an approachable overview of how we obtain information from long-dead animals and what this information can tell us about the environments of the distant past. It will profoundly affect the way palaeontologists and climatologists view the lives of ancient mammals.

"This lucid book argues that studying past communities is essential for understanding how different today's are – and increasingly so. Smith presents the necessary interpretive scientific background, shows how the present differs from even the recent past, and reveals why those changes are so important not only for animals and plants, but for us too."

"This engaging, timely synthesis employs a paleoecologic perspective, mammalian ecosystems of the past, to interpret the present and predict the future. The book is chock full of examples, as Smith draws on more than three decades of field experience in the American Southwest to teach valuable lessons about species diversity, body size, diet, and environmental challenges."

"A lucid introduction to the paleoecology of mammals, drawing on their late Quaternary fossil record from North America. It introduces paleobiologists to ecology while providing a wealth of information concerning fossils for ecologists. Late Quaternary mammals provide critical case studies for assessing the impact of changing climates on species today."
