What Was Australia Like During The Ice Age?
Some 180 million years ago, the supercontinent of Gondwana split. One of the breakaway landmasses from that separation contained what would become Australia and Antarctica. By 30 million years ago Australia had fully separated and journeyed north on its own. Since then, changes in land formation and climate, and the physical separation from the rest of the world, led to the unique flora and fauna that we know in Australia today. More than 80% of our plants, mammals, reptiles, and frogs are unique to Australia and are found nowhere else in the world.
Thousands of years ago, the inland region of eastern Australia was a far cry from the sere place it is today. During the Ice Age, this part of the Southern Hemisphere hosted its own array of big charismatic creatures—answers to the woolly mammoths and saber-toothed cats up north—some of which roamed the then-forested regions of Queensland and Victoria. In a country famous today for its curious and sometimes venomous fauna, Australia’s prehistoric menagerie has proven just as weird, if not weirder.
Australia is so different from the rest of the world because it’s geographically isolated. It broke off from the supercontinent Gondwana 99 million years ago and has been doing its own thing ever since. That’s why it has so many marsupials compared to everywhere else. It was only in the Pleistocene that placental mammals were able to come over from Southeast Asia as the continent drew closer to Indonesia, and then, only bats and rats.
Most large mammals and birds went extinct at the end of the Ice Age, but Australia was the hardest hit of all the continents, with 90% going extinct. Uniformitarians try to explain this via two different hypotheses: either they went extinct because of climate change, or humans hunted them to extinction.
