The Burgess Shale, protected in Canada's Yoho National Park, preserves one of the world's first complex marine ecosystems. The site was discovered in 1909 by paleontologist Charles Walcott and has produced some of the most interesting soft fossils in history. On the website, readers may scout the informative Introduction, and then move on to the Science and History sections, which describe in details the significance of the fossil findings at the Burgess Shale. The Fossil Gallery, with its dozens of photographs of specimens from the site, is another great place to begin. Of special interest, the Virtual Sea Odyssey allows visitors to experience life in the ancient ocean "first hand." The site is available in both English and French.
