    Are Marsupials Only Found In Australia? There are over 330 species of marsupials. Around two-thirds of them live in Australia. The other third live mostly in South America, where some interesting ones include the flipper-wearing yapok, bare-tailed woolly opossum, and don’t get too excited, but there’s also the gray four-eyed opossum.

    Why marsupials are only found in Australia? One line of thinking is that marsupial diversity is greater in Australia than in South America because there were no terrestrial placental mammals to compete with marsupials in ancient Australia. Kangaroos are the only large mammal to use hopping as their primary form of locomotion.

    What marsupials exist outside of Australia? Most people think of Australia when they think of marsupials, because the most well known of the marsupials—koalas and kangaroos—live there. But opossums, which are also marsupials, live in North, Central, and South America.

    Are marsupials found in Europe? In South America they survived alongside placentals, forming a significant part of the Neotropical mammalian fauna. Marsupials also populated Europe, Asia, and North Africa between 125 million and 14 million years ago.

    Why are there no marsupials in Africa?

    Dr Beck says climate change might have played a role in the disappearance of the ‘ameridelphian’ marsupials. The Tingamarra fossil deposits date from 55 million years ago, when the climate was very warm. “It would have been lush rainforest,” he says.

    Why are there no marsupials in New Zealand?

    Actually New Zealand also has native seals, whales, dolphins and sea lions all of which are also mammals. But it’s because NZ was already isolated by a large body of water before mammals evolved. So only mammals who could swim or fly could ever colonise in New Zealand.

    Is a sloth a marsupial?

    Sloths are mammals, but they aren’t primates or marsupials – though the groups do share some similarities.
