Zygomaturus trilobus
Zygomaturus trilobus was a giant, swamp-dwelling marsupial from Ice Age Australia, a member of the diprotodontid family. Its large size and slow movement would have made it vulnerable to human hunters arriving on the continent during the late Pleistocene.
Description
Zygomaturus trilobus — This extinct marsupial was closely related to the modern wombat and koala but reached much greater size, estimated at 2.5–4 meters in length and weighing up to 500 kg. It had a broad skull with three distinct ridges (the “trilobus”), and teeth adapted for grazing tough plants in wetlands and open forests. Likely a browser or mixed feeder, it occupied swampy and riparian habitats across Pleistocene Australia. Like other diprotodont megafauna, Zygomaturus disappeared around 46,000 years ago, coinciding with the arrival and spread of humans.

Hunt History
Although direct butchery evidence is scarce, the timing of Zygomaturus extinction strongly suggests human involvement. Paleoanthropological sites in Australia show evidence of megafauna exploitation, and Zygomaturus—being slow-moving and concentrated in waterholes during dry periods—would have been especially susceptible to ambush hunting or mass drives. Aboriginal oral traditions may preserve faint echoes of encounters with large wombat-like beasts. Most researchers consider overhunting and habitat pressures from human burning practices to be decisive factors in its disappearance.
