Australian scientists exploring uncharted areas of the Indian Ocean said on Thursday they had found sunken parts of the megacontinent Gondwana which could offer clues on how the current world was formed. The two “islands” were found on the remote sea floor in international waters 1,600 kilometers (1.000 miles) west of Australia during a surveying trip last month.
Gondwana 80 and 130 million years ago.
Their rocks contained fossils of creatures found in shallow waters, meaning they were once part of the continent at or above sea level rather than created by undersea volcanic activity, said Sydney University geophysicist Jo Whittaker, one of the key researchers.
She said it was an exciting discovery which would hopefully shed light on how Gondwana broke into present-day Australia, Antarctica and India between 80 and 130 million years ago.
Whittaker said she was particularly interested in exploring India’s drift first northwest and then sharply north, where its northeast coast, once joined to Australia, smashed into Eurasia, forming the Himalayas.
Together with some of the other data this has the potential to change how we’ve been modelling that part of the world and that timeframe… Read full article here
