Ngapakaldia is an extinctgenus of diprotodontidmarsupials, related to the modern koala and wombat. Around the size of a sheep, it was a ground-dwelling herbivore that lived around the vegetated shores of lakes in Central Australia during the Late Oligocene.
Two species are placed with the genus, N. bonythoni and N. tedfordi.[3]
