Scientists Find 280-Million-Year-Old Fossilized Forest…in Antarctica
A team of geologists have discovered remnants of a 280-million-year-old fossil forest in Antarctica. They suggest that the trees of the forest survived through periodic extremes of total darkness and uninterrupted sunlight.
Older than the Dinosaurs
The Independent reported Erik Gulbranson and John Isbell of the University of Wisconsin-Milwaukee are behind this impressive discovery. The two scientists trekked across the Transantarctic Mountains during the continent’s summer, between November and January. They found 280-million-year-old tree fossils among the rocks where a leafy forest once grew. The geologists suggest this is the oldest polar forest ever found in Antarctica.

They had previously discovered fossil fragments of 13 trees estimated to be between 260 and 300 million years old, a fact that indicates that the forest existed even before the first dinosaurs appeared at the end of the Permian period. “Dating the fossils was one of my team’s biggest challenges,” Dr. Gulbranson stated in an interview with CNN , adding that the recent findings showed the polar forest’s age as around 280 million years old - though a margin of error could mean the trees were up to 20 million years older or younger.

Motivated from that discovery, the scientific mission has now returned to the frozen landscape to understand how the forest could have flourished there. “People have known about the fossils in Antarctica since around 1910 but most of the region remains unexplored,” Dr. Gulbranson said via The Independent .
It Grew at a Latitude Plants Can’t Today
Apparently, the polar forest emerged at a latitude where plants can’t grow today, a fact that makes Dr. Gulbranson speculate that the trees probably had to have been a remarkably dynamic species in order to survive. “There isn’t anything like that today,” Dr. Gulbranson said, according to The Independent. And continued,
“These trees could turn their growing cycles on and off like a light switch. We know the winter shutoff happened right away, but we don’t know how active they were during the summertime and if they could force themselves into dormancy while it was still light out.”

Absolute Darkness and Uninterrupted Light
The scientists believe that the trees of the polar forest survived under particularly unusual conditions, as they were living for about seven months in absolute darkness, followed by nearly five months of continuous light. During the Permian Period, Antarctica was much warmer than it is these days, and plant life became dominated by fern-like plants such as Glossopteris (the largest and best-known genus of the extinct order of seed ferns), which grew in swamps. Over time, these swamps became deposits of coal in the Transantarctic Mountains.

Towards the end of the Permian period, continued warming led to a dry, hot climate over much of Gondwana, the Southern Hemisphere’s supercontinent that incorporated present-day Africa, South America, Arabia, India, and Australia. Impressively, the scientific team noticed that the trees managed to transcend from summer activity to dormancy – a period in an organism's life cycle when growth and development are temporarily stopped – during the winter, perhaps as fast as within a month.
What Caused the Forest’s Extinction?
Dr. Gulbranson noted that his team is now trying to understand the cause which led to the mass extinction of the forest. Even though no solid conclusions have popped up yet from the meticulous investigations, several scientists suggest that almost 90% of all species vanished from the face of the earth, the polar forest included, because of the higher global temperatures that followed throughout the years and ocean acidification, most likely caused by an injection of carbon dioxide in the atmosphere for nearly 200,000 years. “This forest is a glimpse of life before the extinction, which can help us understand what caused the event. It can also give clues to how plants were different than today,” Dr. Gulbranson told CNN , hoping that his work may help us to understand the effects of contemporary climate change a little better.

This article you've written is very exciting to read you also reminded me of Genesis in The Bible; about the 3rd Day of Creation when both Dry Land and All the Plants an Trees and grass of every kind came to existence.
Also i'm a Christian I'm in the Seventh Day Adventists church family and at this point I'm probably? I don't know for sure who does believe in Climate Change as strongly as I believe in The Second Coming of Jesus hence is the forgotten reason why we're identified as Christian's.
So I just want to say thank you for sharing your article looking forward to reading more of your articles; Goodbye!
Or, what makes more sense, as posted above, Antarctica was in a much more Northerly location, as indicated by the various maps published prior to the 1800s, showing the location of Antarctica to be in the South Atlantic. Antarctica was moved to its current location very recently (in a Geologic time scale).
280 million years ago, Antarctica was part of Pangaea and probably in temperate latitudes, The continents drifted apart about 220 million years ago, and Antarctica ended up at the bottom of the world.
If it is promoted by CNN means only fraud.
Everything about so called "climate change" as culprit is an absolute nonsense.
More degree and diplomas means absolutely not at all intelligence and to be wise !
