The longest lived "land" mammal after humans is most probably the elephant (Loxodonta africana) at 65+ years. The longest lived "mammal" is most probably the Bowhead whale (Balaena mysticetus) which has been reported to live 211+ years. For further research on this topic you can look up many species in the AnAge database: http://genomics.senescence.info/species/ Its curator has been gracious enough to document the current known longevity of many species.
