Thanks for the ping. There is some dingbat on every tv channel.
Geologists have discovered the remains of three ancient deciduous Antarctic forests, complete with fossils of fallen leaves 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.
Some stumps were even poking through the snowfield in the Beardmore Glacier area, said U.S. geologist Professor Molly Miller of Vanderbilt University in Nashville.
"These were not scrubby little things," Miller said. "These were big trees."
Some are estimated to be as tall as 24.6 meters, based on their trunk diameter.

Wrong. The trees grew there just as european trees grow. They shed their leaves in winter.
fossil tree trunk.
How leaves became fossilized intact is a great unknown IMO. And no one will convince me the trees are all extinct; this one is a eucalypt.
Frozen sand dunes. Puzzling.
