Fossils of huge otter unearthed in China

Scientists have unearthed fossils of an intriguingly large otter as big as a wolf that frolicked in rivers and lakes in a lush, warm and humid wetlands region in south-western China about 6.2 million years ago.  Researchers say the outsized otter, called Siamogale melilutra, weighed about 50 kilograms and measured up to two metres long, making it bigger than any of its cousins alive today.
