Despite their immense size, species of prehistoric giant kangaroos from a site in Queensland were probably homebodies with a surprisingly small range compared to other kangaroos, according to new Australian research.

Protemnodon, which roamed the Australian continent between 5m and 40,000 years ago and is now extinct, was significantly larger than its modern relatives. Some species weighed up to 170kg, making them more than twice as heavy as the largest red kangaroo.
