Australian faunal subregion

Quick Reference

A region that is distinguished by a unique marsupial (Marsupialia) fauna, including herbivores, carnivores, and insectivores. These evolved in isolation from the placental mammals (Eutheria) which now dominate the other continental faunas. In addition to marsupials there are also very primitive mammals (Monotremata), the spiny ant-eater and the platypus; and small rodents which are relatively recent (probably Miocene) immigrants.
