Two meteros each 10km across left a 400km impact zone in Australia . A team of researchers found the crater two kilometres underground . Researchers say the impact could have caused mass animal extinctions . The zone was found with high velocity shocks and drilling into the Earth . The impact may have happened around 300 million years ago .
