The Mammals Collection at The Field Museum contains more than 230,000 preserved specimens representing all orders and all but one extant family (the monotypic bat family Craseonycteridae) and is worldwide in scope, with strong geographic representation from the Neotropics, Afrotropics, Indo-Malay, Nearctic, and Palearctic regions.

Resident staff support an active program of research, curation, and education with assistance from honorary associates, students, and volunteers. We currently pursue research programs in Africa (including Madagascar), Asia, North America, and South America in active collaboration with colleagues in each of those areas. Our research often results in the discovery of new species, generates new information on the ecology and evolution of mammalian biodiversity, and leads to more effective protection of threatened species.
