Did you know that outside Australia there are also marsupials. These kind of mammals that were displaced from most of the world by modern mammals after the breaking of Pangea into several continents, prospered very well in isolated Australia, and managed to just survive in isolated niches in South America, like in Chile. Sure, our marsupials are just rat-sized, but it is interesting they still survived in an hostile environment full of euterians (modern mammals).

Here, some of them.  Unfortunately, these cute species are in danger of extinction.

Did you know that a species of Kangaroo still exists in Papua New Guinea.
 
 They inhabit the tropical rainforests of New Guinea and far North Eastern Queensland, and some of the islands in the region. Most tree-kangaroos are considered threatened due to hunting and habitat destruction.
 

 
 
 
As can be seen from the photo, they differ in appearance to the normal Kangaroo.

It's not that I was born in Ireland,
It's the Ireland that was born in me.

It should be kept in mind, that the marsupialia once originated in Asia and became dominant during the cretaceous era in Northern America, while they got extinct in Asia. From North America the marsupiali spread to europe and asia again, but got extinct during the Miocene. The modern marsupialia in North America are immigrants from the South, that came about 3my ago.
It is difficult to say, but it seems, that marsupialia did not arrive in South America before the early Palaeocene. Before Antarctica and Australia could drift too far away, the Drake street opened after 40 my BP, the first marsupialia entered as well the ice-free Antarctica and appeared in Australia during the early eocene, 55my ago.

Where else in the world do Marsupials exist?

By the way, there are also some trees shared between Australia and South America, I believe. Monkey-Puzzle trees, also known as Araucarians, for instance.

There is also one native North American marsupial, the Virginia Opossum (Didelphis virginiana).

Thanks for your input folks, I always thought that Australia was the last habitat for marsupials.

It's the Ireland that was born in me.
