Extract

There are three living infraclasses of Mammalia: Prototheria (Monotremes), Metatheria (Marsupials), and Eutheria (Placentals). The egg-laying, poison-spurred and in other ways morphologically reptile-like monotremes now inhabit Australia and New Guinea. Whereas discussion of their past history (Miocene and Pleistocene of Australia; Woodburne and Tedford, 1975) would be a fascinating topic, that group will not be discussed further here.
