The two 'islands' were found on the remote sea floor in international waters 1,600 kilometres (1,000 miles) west of Australia during a surveying trip last month. 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. 'We have a fairly good idea where those continents were but we don't exactly know, the eastern Indian Ocean is one of the more poorly explored parts of the world's oceans in terms of tectonics,' she told AFP. 'So it will help us figure out the plate kinematic motions that led to India moving away from Australia and heading up off to crash into Eurasia.' Samples of sandstone and granite were dredged from a steep cliff on one of the islands, about 2,000 metres (6,600 feet) below the ocean surface, are to be dated but the research team believe they are up to one billion years old. The rocks would also be compared with samples from Australia's west coast to try to determine where exactly the islands broke away from. Similar matching was not possible with India because the relevant coast was now 'smashed into the Himalayas somewhere,' said Whittaker. She likened the continental separation to pulling something 'a bit gooey' apart and said the fragments, which are a fraction of the thickness of normal continental crust and combined about the size of Scotland, were the 'little pieces that got left behind.' 'It's very significant, it's not every day you discover two large continental fragments on the ocean floor,' she said. '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.'
