Brett Smith for redOrbit.com - Your Universe Online The biggest known carnivorous marsupial of the modern era – the Tasmanian tiger - or thylacine - went extinct in the early 20th century. Now, researchers have found that a distant, ancient relative of the thylacine was able to hunt down prey larger than itself, according to a new study in the open-access journal PLOS ONE. Based solely on a recovered 16- to 11.5-million-year-old skull, the study team was able to create a virtual...

Dingoes Wrongly Accused Of Animal Extinctions
2013-09-10 17:32:10

Lee Rannals for redOrbit.com – Your Universe Online Scientists writing in the journal Ecology say that despite popular belief, the Australian dingo should not be blamed for mass extinctions. Dingoes have been blamed for the extinctions of the Tasmanian tiger and the Tasmanian devil on the Australian mainland about 3,000 years ago. Instead, the scientists blame Aboriginal populations and a shift in climate. "Perhaps because the public perception of dingoes as 'sheep-killers' is so...

Tooth enamel reveals diet, habitats of extinct marsupials in southeastern Queensland The teeth of a kangaroo and other extinct marsupials reveal that southeastern Queensland 2.5-5-million-years ago was a mosaic of tropical forests, wetlands and grasslands and much less arid than previously thought. The chemical analysis of tooth enamel that suggests this diverse prehistoric habitat is published June 12 in the open access journal PLOS ONE by Shaena Montanari from the American Museum of...

Humans Not Responsible For Megafauna Extinction

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...

When, how and why modern humans first stood up and walked on two legs is considered to be one of the greatest missing links in our evolutionary history. Scientists have gone to the far ends of the earth — and the wonderful creatures in it - to look for answers to why we walk the way we walk. In the latest such search, researchers from the University of the Witwatersrand in Johannesburg (South Africa) have taken a closer look at bipedal kangaroos and wallabies and how they move...

Tasmanian Devils Should Be Less Aggressive To Survive
2012-09-05 10:13:25

April Flowers for redOrbit.com - Your Universe Online Tasmanian devils are carnivorous marsupials found on the Australian island state of Tasmania. The size of a small dog, the Tasmanian devil is known for its muscular build, black fur, pungent odor, extremely loud and disturbing screech, keen sense of smell and ferocity when feeding. That ferocity is causing the problem, and maybe the extinction of the animal. Devil Facial Tumor Disease (DFTD), a fatal infectious cancer spread by...

Eastern Quoll, Dasyurus viverrinus
2014-05-19 12:50:49

The eastern quoll (Dasyurus viverrinus), or the eastern native cat, is a species of marsupial that is native to Australia. Its range once included mainland Australia, but it is still common on Tasmania. This species is one of six living quoll species and was named for its ferret-like appearance. George Shaw, who classified it with possums in the Didelphis genus, first discovered it in 1800. Male eastern quolls reach an average body length of 23.6 inches and weight of 2.8 pounds. This...
