Metatheria or Marsupials - Mammals
Metatherians are highly adapted creatures and today most of them are to be found in Australasia while some species hold out against the onslaught of their eutherian cousins in Central and South America. Origins. Metatheres diverged from the mammalian lineage leading to eutherian (placental) mammals by the Middle Cretaceous.

Metatheria: Characters and Distribution | Chordata | Zoology
Metatheria were widely distributed over many parts of the world as recently as the Miocene period. But they are now confined to the Australian region (except New Zealand), to South America and a few species to North America. 1. Distribution: Almost entirely continued to the Australian region with the exception of the American opossums. 2.
