Giant extinct kangaroos' preference for home over roaming may have sealed their fate
- Researchers predicted the home range of the prehistoric giant kangaroo Protemnodon using fossil data in a study published in PLOS One.
- Scientists expected larger ranges based on the animal's size, up to 170 kilograms, but previous research suggested limited hopping ability.
- Analyzing isotopes in teeth from Queensland deposits revealed ranges matched local geology, not distant areas or larger expectations.
- Lead researcher Chris Laurikainen Gaete stated, "habitat, not body size, was the key" factor determining the range.
- Small home ranges likely contributed to their extinction around 280,000 years ago when climate change disrupted their stable rainforest habitat.

Australia: Prehistoric giant kangaroos victims of a "climate upheaval"
Prehistoric giant kangaroos perished massively during a period of "climate upheaval" in Australia, victims of their sedentary lifestyle when the tropical forest turned into a desert, revealed a study published on Thursday.
Here's how a change in climate made Australia's giant kangaroos vanish
A new peer-reviewed study has found that, unlike modern kangaroos, the extinct marsupial megafauna Protemnodon were less mobile, which they believe, along with a change in climate, led to their extinction.
We're learning more about ancient giant kangaroos
Giant kangaroos should have giant home ranges, but researchers were shocked to find that the largest of them all, Protemnodon, was a real homebody. Habitat, not body size was the key says lead researcher, Dr Chris Laurikainen Gaete, from the University of Wollongong. Protemnodon was a genus of the giant forest kangaroos that lived until about 40,000 years ago in Sahul, the super-continent comprising Papua New Guinea, Australia and Tasmania and t…
Giant extinct kangaroos' preference for home over roaming may have sealed their fate
Giant kangaroos stuck close to home and went extinct when climate change caused that home to disappear, according to a study published in PLOS One by Christopher Laurikainen Gaete of the University of Wollongong, Australia, and colleagues.
