Nova Scotia's Joggins fossil cliffs, regarded as the best record of life in the Coal Age 300 million years ago, have been added to the exclusive ranks of World Heritage Sites designated by UNESCO.
For nearly 200 years, scientists have been fascinated with the 10-kilometre stretch of cliffs at the head of the Bay of Fundy, where tides continually erode stone to expose fossils dating back to hundreds of millions of years ago. The site has even garnered a mention in Charles Darwin's landmark work, On the Origin of Species.
