Did a comet really smash into Canada 13,000 years ago?
A team of U.S. scientists that has unearthed a layer of microscopic diamonds on a California island (USA) is calling the find a possible 'smoking gun' to prove a controversial theory that debris from a massive comet - believed to have smashed into northern Canada nearly 13,000 years ago - wiped out the woolly mammoth and dozens of other Ice Age mammals, triggered a 1,000-year period of global cooling and threatened the fragile foothold of North America's earliest human inhabitants.
The discovery of 'shocked' nano-diamonds at Santa Rosa Island, located about 150 kilometres west of the Los Angeles shoreline, is being described as 'the strongest indicator yet' that prehistoric North America was rocked by a catastrophic cosmic explosion - with Hudson Bay the suspected epicentre of destruction. Several studies over the past few years have identified a telltale layer of charred material, hyper-radiated sediments and other traces of an extraterrestrial impact at a host of 12,900-year-old archeological sites across the U.S. and Canada, including three in Alberta and one in Manitoba. Controversy surrounds the theory that a comet blast was responsible for the Ice Age extinctions of so-called 'megafauna' species such as North American mammoths, camels and horses.
