A team of archaeologists, palaeontologists and traditional owners have found the teeth of a rhinoceros-sized wombat during a dig at a swamp in Victoria.

The team found inch-and-a-half molars from a Diprotodon, which is the largest known marsupial species weighing about one tonne, reported the ABC.

The dig at Lancefield Swamp, a rich fossil deposit from the Ice Age which is about an hour north of Melbourne, also included Museum Victoria and took place over the past week.

Dr Jillian Garvey told the ABC it was the biggest marsupial that had ever lived and was about the size of a four-wheel drive or a rhinoceros.

As well as the enormous marsupial, the team also found teeth and limb bones from a giant extinct kangaroo called the Macropus Titan and Aboriginal artefacts.

According to La Trobe University previous digs at the site have found skeletons of giant kangaroos, rhinoceros-sized wombat-like animals and marsupial lions.

Dr Garvey said they hoped the dig would uncover the mystery of how such a large number of fossils ended up there.

She said it was previously thought the concentration of fossils could have been a result of human hunting and that the animals got bogged, but she said it was more like they came from another water channel somewhere else.

Dr Garvey said in the 1970s it was thought some of the fossils were around the 25,000 year-old mark - but more recently some people have surmised they might be 50,000 to 80,000 years old.

'We don't really know much about the megafauna and what happened to them. It's a big contentious debate. Was it humans? Was it climate,' she said.

She added that some other areas of the swamp could have bone pits from different time periods.

'These animals are far more fascinating. They're so unusual. One had meat shearing teeth. They're just bizarre,' she said.

Fossils were first located at the swamp in the 19th century, and there were digs at the site in the early 1990s, 2004 and 2005.

The excavation will finish up on Saturday, to coincide with the start of a megafauna festival.
