Scientists discovered a giant wombat

Animatronic Diprotodon at the Wonambi Fossil C...
Wombats dig extensive burrow systems with rodent-like front teeth and powerful claws. One distinctive adaptation of wombats is their backwards pouch. The advantage of a backwards-facing pouch is that when digging, the wombat does not gather dirt in its pouch over its young. Although mainly crepuscular and nocturnal, wombats also venture out to feed on cool or overcast days.

Scientists in Australia have discovered the fossil of a giant wombat, which, at the size of a rhinoceros, would have been the largest marsupial to ever live. The creatures are believed to have gone extinct just 55,000 years ago, either due to the arrival of humans or climate change.

Wombats are large burrowing mammals found only in Australia. Being rather timid and primarily nocturnal, they're difficult to observe in their natural habitat and haven't been well studied. They weren't even noticed by European settlers for ten years.

Wombats use their claws to dig burrows in open grasslands and eucalyptus forests. They live in these burrows, which can become extensive tunnel-and-chamber complexes. Common wombats are solitary and inhabit their own burrows, while other species may be more social and live together in larger burrow groups called colonies.

WOMBAT, common name for three species of
burrowing herbivorous (plant eating)
MARSUPIAL (Mammals that carries its young in a pouch).
Wombats have long claws that are adapted for digging, and they live in burrows, from which they emerge at night to feed on grasses and other plants.

but whatever got in its way would have been trampled to death, scientists agreed today after the first complete skeleton of a prehistoric monster was found in Australia.

Known as a diprotodon and likened to a giant wombat, weighing three tons and stretching up to 14ft long, it roamed the Australian continent between 25,000 and two million years ago.

What is known, from a fragment of bone from the remains of another diprotodon discovered in New South Wales, is that these creatures lived on the continent at the same time as the early Aborigines.
