Tropical fossil forests unearthed in Arctic Norway
UK researchers have unearthed ancient fossil forests,
thought to be partly responsible for one of the most dramatic shifts in the Earth’s climate in the past 400 million years.
(I didn't realize the man maid is such an old bag)
The fossil forests, with tree stumps preserved in place, were found in Svalbard, a Norwegian archipelago situated in the Arctic Ocean. They were identified and described by Professor John Marshall from Ocean and Earth Science at the University of Southampton and Dr Chris Berry of Cardiff University and.
Professor John Marshall has accurately dated the forests to 380 million years.

Ellesmere Island Eocene Fossils
Some 55 million years ago, during the early Eocene Epoch, ELLESMERE Island in Canada's eastern High Arctic was warm and ice-free. It was also home to lush lowland forests and swamps inhabited by alligators, giant tortoises, snakes, lizards, and a host of mammals that included primates, tapirs, hippo-like Coryphodon, and large, rhino-like brontotheres.
In the nearby ocean, clams and snails thrived. This extinct environment, well above the ARCTIC CIRCLE, combined a warm temperate climate with a typical Arctic light regime of bright summers and dark winters.
