Why did the marsupial lion go extinct?
Why did the marsupial lion go extinct?
The extinction of one of Australia’s top predators, Thylacoleo carnifex – aka the marsupial lion – was likely a result of changing weather patterns and loss of habitat rather than human impacts, new research has found. The animals survived even past the influx of humans to the continent roughly 60,000 years ago.
When did marsupial lion exist?
about 24 million years ago
“Marsupial lions” lived on the Australian continent from about 24 million years ago up until the end of the Pleistocene era, about 30,000 years ago. Of course they weren’t really lions, but an extinct species of marsupial with lengthened premolar teeth.
How was the marsupial lion discovered?
The beast, which lived during the Pleistocene epoch from about 2 million to 50,000 years ago, was first described in 1859. Back then, pieces of its skull and jaw were collected at Lake Colongulac in Victoria, Australia, and sent to Sir Richard Owen at the British Museum, the researchers said.
Is the Thylacoleo real?

Why is it called a marsupial lion?

Why are marsupials found only in Australia?
Why are the majority of current-day marsupials 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.
When did the marsupial lion go extinct?
Along with many of the other unusual mammals that once roamed Australia, the marsupial lion became extinct around 40,000 years ago.
