|Present-day distribution of marsupials.|
Reproduction[change | change source]
Marsupials have a special pouch where they carry their joeys. After the birth the joey goes into its mother's pouch, where it can drink milk and is kept warm and safe. When the joeys are young they stay in the pouch all the time, but when they are older they can leave it for short times. When they are old enough and too big for the pouch they do not go into their mother's pouch anymore.
Biogeography[change | change source]
They were outcompeted on Laurasia by placental mammals, but the placentals did not get into the Australasian part of Gondwana before it broke away into a separate supercontinent. That is why marsupials now found native only on the southern continents of Australasia and South and Central America, with the single exception of the Virginia opossum.

Thingodonta[change | change source]
The extinct genus Yalkaparidon (Order Yalkaparidontia) is a bizarre fossil found in the Oligocene/Miocene deposits of Riversleigh, NE Australia. Its teeth are so strange that palaeontologists call it a 'Thingodont'.
