These early ancestors were about the size of a pet cat and fill in a 30 million year evolutionary gap for marsupials.
and filled in different ecological niches in the forests that flourished in central Australia about 25 million years ago. The was “kind of the koala heyday,” according to the Flinders University paleontologist and study co-author Gavin Prideaux.
“Until now, there’s been no record of koalas ever being in the Northern Territory; now there are three different species from a single fossil site,” Prideaux. “While we have only one koala species today, we now know there were at least seven from the late Oligocene – along with giant koala-like marsupials called ilariids.”
At this time, iliariids were the largest marsupials living in Australia, weighing in at up to 440 pounds. Iliariids lived alongside a strong-toothed wombat relative named
