Fossilization is a rare process and paleontologists are used to having to build an image of an animal from incomplete remains. So when paleontologists unearthed a mass grave of Diprotodon skeletons and other Australian megafauna in June 2012, they couldn't believe their luck.

"It's a palaeontologist's goldmine where we can really see what these megafauna were doing, how they actually behaved, what their ecology was," said Scott Hucknall (Queensland Museum in Brisbane) told the BBC. "With so many fossils it gives us a unique opportunity to see these animals in their environment, basically, so we can reconstruct it."

The Queensland site is thought to hold the remains of 50 Diprotodons - the largest marsupial to ever live, about the size of a rhino, and often referred to as "a mega-wombat" (Hucknall likens it to "a cross between a wombat and a bear"). One of these fossils, named Kenny by the researchers, is the biggest Diprotodon ever found and has a jawbone of around 70 cm (about 28 inches) long. The fossils are between 100,000 and 200,000 years old, but Diprotodon is thought to have been around until 50,000 years ago when the first humans appeared in Australia - though it's greatly debated what role humans may have played.

It's thought that these animals were attempting to take refuge from a drought and mistakenly entered a boglike environment. They are not the only fossils there. The teeth of a 6 metre (20 foot) long lizard named Megalania and the teeth and back plates of a huge prehistoric crocodile have been uncovered, as have fossils of 2 and a half metre (8 foot) kangaroos.
