Climate Change, the Cause of Australian’s Giant Animal’s Extinction?
Researchers from Australian National University have recently submitted a report detailing about the possible cause of extinction of giant animals in Australia's Southeast. The report mentions that climate change has played a major role in wiping out the species from the mainland approx 50,000 years ago.
Above are the conclusions of the studies that the experts have performed for years with the help of the sediment core that was collected from offshore the Murray River.
The report clearly mentions that due to change in climate, the three meter-tall flightless birds i. e. the giant kangaroos and the Tasmanian tiger disappeared from the region.
The above research was performed under the guidance of Professor Patrick De Deckker from the ANU Research School of Earth Sciences. It is the work piece of his ANU colleagues and a team of scientists from the Netherlands.
"The extinction happened around the same time as humans moved into the area, which also coincided with a change in the type of plant food available to megafauna," Professor De Deckker said.
Experts have yet not been able to confirm the exact timings of extinction and the climate change.
They have-not only reconstructed the sea-surface temperature over the past 135,000 years, but they also succeeded in creating the variations of the vegetation in the Murray Basin. They noticed a variation of three degrees in the sea-surface temperature at the time of the extinction.
