“A couple of locals called me up and asked me if I’d like to come and collect it safely for the museum,” McCurry told Guardian Australia. “If people were to try and collect these without any experience, it’s quite likely that they’d be broken and we’d lose information.”“A couple of locals called me up and asked me if I’d like to come and collect it safely for the museum,” McCurry told Guardian Australia. “If people were to try and collect these without any experience, it’s quite likely that they’d be broken and we’d lose information.”
Diprotodons were a type of megafauna that were widespread across Australia and co-existed with the Indigenous population for thousands of years. The exact time of extinction is contested and estimates vary between 7,000 and 40,000 years ago.Diprotodons were a type of megafauna that were widespread across Australia and co-existed with the Indigenous population for thousands of years.

They likely fed on shrubs and forbs and may have eaten much as 100 to 150kg of vegetation daily, using its chisel-like incisors to do so. It is the largest known marsupial to ever have lived.

Their bones have been found throughout Australia but they preferred semi-arid plains, savannahs and open woodlands, according to the museum. One skeleton found at Lake Callabonna, in the far north region of South Australia, had the remains of saltbush in its abdominal region.Their bones have been found throughout Australia but they preferred semi-arid plains, savannahs and open woodlands, according to the museum.

McCurry said the creatures, which were roughly the size of a rhinoceros, were sometimes called “giant wombats”, though researchers did not know how “closely they are related”.McCurry said the creatures, which were roughly the size of a rhinoceros, were sometimes called “giant wombats”, though researchers did not know how “closely they are related”.
“At the same time that mammoths were roaming around the northern hemisphere, Australia had its own unique set of large mammals,” McCurry said.“At the same time that mammoths were roaming around the northern hemisphere, Australia had its own unique set of large mammals,” McCurry said.
The reason for their extinction is also unknown. Researchers have suggested that humans may have played a role, either through the hunting of juveniles or through changes to their habitat caused by farming practices.The reason for their extinction is also unknown.

The fossil is unlikely to be displayed at the museum and will instead be available to researchers from around the world to study.The fossil is unlikely to be displayed at the museum and will instead be available to researchers from around the world to study.
“The fossil record is very incomplete. Very few animals turn into fossils and when they do they are often broken up. We don’t have that much information about extinct species,” McCurry said.“The fossil record is very incomplete. Very few animals turn into fossils and when they do they are often broken up.

“This is a reasonably complete jaw, it’s not isolated broken teeth with all of the teeth. Finding those types of fossils add to our understanding of what these animals are like.” “This is a reasonably complete jaw, it’s not isolated broken teeth Finding these types of fossils add to our understanding of what these animals are like.”
