Reconstruction of Alkwertatherium webbi (at rear) next to Kolopsis torus by P. Murray

Alkwertatherium webbi was a large marsupial almost the size of a rhinoceros that looked like a big wombat. It weighed about 400 kilos and was about 1 metre tall and 2.5 metres long. Like the Pyramios alcootense, the Alkwertatherium webbi had a long snout with a mouth like a scoop. This was probably used for finding food under the ground such as tubers, or semi aquatic plants along a river's edge.

They also have a very narrow skull and jaw bone. Alkwertatherium webbi are extremely rare in the Alcoota area.

Alkwertatherium survived through almost all the Miocene period, or from 24 - 5 million years ago. Australia had been separated from the big southern landmass of Gondwana for millions of years by this time. The animals of Australia had evolved very slowly in almost complete isolation from the animals of other continents. There were forests and a permanent water supply at Alcoota where the Alkwertatherium webbi lived.

Scientists don't know for sure how Alkwertatherium webbi died out but they think it might have happened because of a drought that led to a shortage of food.
