An international team of Scientists have revealed that Antarctica went through a heat wave nearly 15.7 million years ago during which plants and algae were abundant. The team led by LSU Museum of Natural Science in Washington said, it has found evidence of the warm period in Antarctica that lasted for a few thousand years by analysing fossils.<br/> <br/>Among the 1,107 meters of sediments recovered and analysed for microfossil content, a two-meter thick layer in the core displayed extremely rich fossil content. The scientists said, the finding will open a new window for understanding evolution of life on earth.<br/> <br/>
