Arctic Mammal Fossils and Forests of 50 Million Years Ago

The Arctic was a warm, wet, swampy, forested place 50 million years ago. Ellesmere Island is a key fossil site in Canada's High Arctic, where the remains of unique mammal species can tell us what the environment and animals of the Eocene Epoch were like. Scientists are studying these fossils to better understand our warming planet. — Canadian Museum of Nature
