he Museum's mammal halls are among its most renowned and beloved. With precise depictions of geographical locations and the careful, anatomically correct mounting of the specimens, the Museum's dioramas are windows onto a world of animals, their behavior, and their habitats. Moreover, since many of the environments represented have been exploited or degraded, some dioramas preserve places and animals as they no longer exist. The visitor to these halls is able to travel not only across continents, but also, in some cases, through time.
