This paper introduces a new database, “Mammalian Intercontinental Communities for Ecology” (MICE), which seeks to increase and improve, among others, the available material used in palaeoecological studies. Information on climate and terrestrial mammalian communities will be obtained for 500 localities from all around the world. Based on such information, both palaeoecological and neoecological studies will be produced. Problems identified in previous works are being taken into account while the new database is being compiled. When complete, this database will be uploaded to the World Wide Web in order to make it available to the scientific community. It will be interesting to see how the future development of MICE, with a strong dynamic and interactive character, will stimulate production in various scientific fields
