Euryzygoma
Euryzygoma is an extinct genus of marsupial which inhabited humid eucalyptus forests in Queensland and New South Wales during the Pliocene of Australia. Euryzygoma is believed to have weighed around 500 kg, and differed from other diprotodonts in having unusual, flaring cheekbones that may have been used either for storing food or for sexual display. Euryzygoma is believed to be the ancestral genus from which Diprotodon evolved.
