Both specimens were remarkably well preserved thanks to the cold and dry conditions of the cave in which they were found."The ancient DNA reveals that extinct giant wallabies are very close relatives of large living kangaroos, such as the red and western grey kangaroos," said Dr. Bastien Llamas.

The team also discovered that the giant short-faced kangaroo, which has no living descendants, does in fact have a modern-day cousin in the form of the banded hare-wallaby, an endangered species that can be found only on a few isolated islands off the west coast of Australia.

"Our results suggest the banded hare-wallaby is the last living representative of a previously diverse lineage of kangaroos," said study co-author Mike Lee. "It will hopefully further encourage and justify conservation efforts for this endangered species."
