Antarctic Fossil Prompts Rethink About Amphibian History

The fossilised remains of an amphibian which lived more than 245 million years ago have been found in Antarctica, suggesting that the climate during much of the Triassic era was remarkably balmy.

The 60-centimetre (24-inch) piece of skull was teased out of thick sandstone at Fremouw Peak in the Transantarctic Mountains, just six degrees short of the South Pole.

Palaeontologists in Europe and the United States have identified the beast as a Parotosuchus, a two-metre-long (6.5-feet) giant salamander-like predator that lived 40 million years before the first dinosaurs, inhabiting lakes and rivers.
