What are some extinct animals of South America?

For about 20 million years, between 23 and 3 million years, South America was an island continent with its own unique fauna. The starting point for this diversification was inherited from the Supercontinent of Gondwan, which consisted of South America associated with Antarctica (which was forested at that time) and Australia for about 150 million years. This unique Fauna of Gondwans included numerous marsupials (now divided between Australia and South America), including carnivorous Marsupials, Ratite (now represented by Rhea, Emu and ostrich), various bird fauna and unique plants, including many Cycad) Beautiful pink and white flowers. Many of them are not extinct animals or plants, but a large number of their relatives have disappeared over the last few millions of years. Hes, until 3 million years ago with North America, an event known as a large American exchange. Previously, endemic mammals in South America consisted of warning, xenarthans (ArmadilloS, antiTreaters and sloths), many different ungulates (extinct orders notingulata- "southern relaxed"), litopterns (middle rabbit and fur and fur and fur), and horses), and horses), and horses), and horses), and horses), and horses). horses and horses) and horses and horses and fur and fur, and fur and Astrapotheres (sometimes called "a hybrid between a small elephant and a large tapir") and pyrother (large, mastadone/tapir lipot). Most of them are extinct animals. The whole Clade of Endemic South American ungulates, Meridungulata, consists of extinct animals.

Unlike Afro-Eurasia, dominated by placental mammals, and Australia, dominated by marsupials, South America was a unique evolutionary battlefield, where placenta, Marsupials and several odd other ("terrorist birds") competed. Finally, the warning and terrorist birdY lost, amazed by Africaeurasian placenta who attacked during a large American exchange. Many of the marsupials that have not joined the ranks of extinct animals are small and live high in the Andes Mountains, the longest mountains on the ground. Some of the extinct animals that lived in South America, categorized as marsupials include thylacosmilus , a sausage Marsupial predator and borhyaenides, otra/wolverine shaped by Marsupial predators. Opposum was ubiquitous and more numerous than today.
