250 million-year-old amphibian fossils from Australia reveal global spread of ‘sea-salamanders’

The Kimberley region in the north-west corner of Western Australia is full of rugged ranges and gorges, and long stretches of red soil and rocky ground. The dry seasons are long, and the wet seasons often flood the Martuwarra Fitzroy River – an artery to the Indian Ocean – in the region’s south.
