April Flowers for redOrbit.com - Your Universe Online An international team of researchers led by the University of New South Wales (UNSW) has completed a major review of the available evidence to conclude that most species of gigantic animals that once roamed the Australian continent disappeared before the arrival of humans. These findings were published in the Proceedings of the National Academy of Sciences and challenge the claim that humans were the primary cause of extinction for...

Experts in Britain and Australia report that many prehistoric species became extinct as a result of humans, not climate change.  In places like Tasmania, human hunting may have wiped out the large ancient animals, the scientists said. It's a pattern that may also have played out on other islands throughout the world, such as Great Britain.  For years, scientists have debated the underlying cause of widespread extinctions of a large numbers of species during the end of the last Ice...

By Price, Gilbert Analysis of thousands of Diprotodon fossils has resolved the debate about how many species of this ancient giant wombat existed - and uncovered some clues to their behaviour. Imagine you could travel back in time to a period not more than 100,000 years ago. What sort of world would you have seen? What was the landscape like ? What sort of animals would you likely encounter? This was a harsh period in the Earth's history, subjected to massive shifts in climate and...

Pound for pound, Australia's extinct marsupial lion (Thylacoleo carnifex) would have made mince meat of today's African lion (Panthera leo) had the two big hyper-carnivores ever squared off in a fight to the death, according to an Australian scientist. New research published in the Journal of Zoology suggests that Thylacoleo killed prey rapidly, using its "bolt-cutter" type teeth to scissor through hide and flesh to produce major trauma and blood loss. By contrast, African lions and similar...

CANBERRA, Australia - Australia's giant prehistoric animals, including 10-foot-tall kangaroos and wombat-like creatures as big as a rhinoceros, were likely wiped out by aboriginal settlers, not climate change, a researcher said Tuesday. The question of what killed Australia's so-called megafauna during the last Ice Age divides paleontologists. The most popular theories are that climate change drove the giants to extinction more than 40,000 years ago or that Aborigines, who arrived in...
