From Killer kangaroo, demon duck of doom roamed Outback:
“Because they didn’t hop, these were galloping kangaroos, with big, powerful forelimbs. Some of them had long canines (fangs) like wolves,” Archer told Australian Broadcasting Corp radio.Vertebrate paleontologist Sue Hand said modern kangaroos look almost nothing like their ferocious forebears, which lived between 10 million and 20 million years ago.
The species found at the dig had “well muscled-in teeth, not for grazing. These things had slicing crests that could have crunched through bone and sliced off flesh,” Hand said.
