"Geologists have discovered in Antarctica the remains of three ancient deciduous forests complete with fossils of fallen leafs scattered around the tree trunks. The clusters of petrified tree stumps were found upright in the original living positions they held during the Permian period." "Unlike any trees today, the long-extinct Glossopteris trees lived in stands as thick as almost a thousand per acre just 20 or 25 degrees from the South Pole, a latitude at which they received no sunlight for half the year."
