This chapter describes fossil deposits of mammals in the Badger Room of Porcupine Cave. The Badger Room is a small chamber in the Porcupine Cave system located approximately 25 m from the modern entrance to the cave. The Badger Room mammal fauna is very diverse; it contains abundant lagomorph, rodent, and carnivore remains. Some of the specimens were used to explore the paleoclimate of the region surrounding the cave. The climate spaces occupied by each species were assumed to encompass the physiological tolerance limits of each taxon with regard to temperature and moisture. The chapter also used autecological estimates for habitat reconstruction and analysis of the community structure of the mammal fauna.

Keywords:   mammals, Badger Room, lagomorph, rodent, carnivore, paleoclimate, autecological estimates, habitat reconstruction
