Pyramids are popping up everywhere you look, we just posted that Archaeologists Find Underground Pyramid at Tiahuanaco in Bolivia and don’t forget the Pyramids in Italy.
I thought this was an interesting find in the Huffington Post:
Some 250 million years ago, during the late Permian and early Triassic, the world was a greenhouse, much hotter than it is today. Forests carpeted a non-icy Antarctic.
But Antarctica was still at a high latitude, meaning that just as today, the land is bathed in round-the-clock darkness during winter and 24/7 light in the summer.
The question, said Patricia Ryberg, a postdoctoral researcher at the University of Kansas Biodiversity Institute, is how plants coped with photosynthesizing constantly for part of the year and then not at all when the winter sun set.
“The trees are the best way to figure this out, because trees record physiological responses” in their rings, Ryberg told LiveScience.
A microscopic look at Antarctic wood from the Triassic period, when forests carpeted this now-icy continent.
Mixed Results
Follow-up studies analyzing carbon molecules in the fossil wood also gives both deciduous and evergreen answers, Ryberg said. The implication is that ancient Antarctic forests may have been a mix of deciduous and evergreen.
“It’s not one or the other,” she said. “It’s actually both.”
Much of the ring structure looks tropical, Ryberg added. Tropical trees that are not exposed to seasons experience a sort of short-term dormancy that echoes what is seen in the Antarctic wood.
“But they weren’t growing in the tropics, so obviously it’s two different environmental characteristics,” Ryberg said.
Ryberg is now investigating how much plant matter these strange Antarctic forests produced. It’s not yet clear whether the forests grew more densely than those seen in modern forests.DENVER — Strange forests with some features of today’s tropical trees once grew in Antarctica, new research finds.
