Euryzygoma

Euryzygoma is a genus of marsupial which inhabited humid eucalyptus forests in Queensland and New South Wales from the Pliocene to the Late Pleistocene of Australia.[1][2] Fossils assigned to Euryzygoma suggest that the last species went extinct in the Quaternary extinction event.[3]Euryzygoma is believed to have weighed around 500 kg,[4] and differed from other diprotodonts in having unusual, flaring cheekbones that may have been used either for storing food or for sexual display.[5]
