Fly fossil found in Antarctica
Netscape ^ | May 25, 2003

It's just a tiny fossil of a fly that scientists found some 300 miles from the South Pole. But this fossil will help them: --figure out what life was like millions of years ago in ancient Antarctica and --help explain global changes in today's climate. One of the biggest surprises of the discovery: No one even knew there were flies in this frozen land where summer temperatures are a bone-chilling 20 degrees below zero. The fly fossil is from the Cyclorrhapha family, the so-called "higher flies" that include the common housefly, reports CNN.

North Dakota State University geologist Allan Ashworth, who found the fossil and is recognized as a pioneer in using insect fossils to research climate changes, speculates that flies could have existed during a short-lived warm spell in Antarctica several million years ago. They could also have been part of the animal life on a mega-continent called Gondwana that later split up and formed Antarctica, South America, India, Australia, New Zealand, and Africa. Finding such fossils is "painstaking stuff," Ashworth admitted. But the payoff can be huge because so much can be learned from them. CNN reports that the fossil Ashworth found in Antarctica is 5 to 7.5 millimeters long. The fly is actually in the puparium stage, which is similar to the butterfly's cocoon state--a transition period between the larva and adult insect.

So now the big question to be pondered: If a warm spell in Antarctica allowed the fly to live there, what caused the temperatures to rise? Some 15 million years ago, it was not greenhouse gases to blame. So what was it? This ancient clue could help scientists learn more about global warming now. The findings were published in the British journal Nature.

The fly was found sitting in a tiny SUV.

Later in the article they talked of a warming period 15 mya which is confusing because Gondwana ceased to exist about 95 mya when splitting off of Austrailia .

Biblically, a better question is "what caused the temperatures in Antarctica to fall?"

Maybe the flies rode in on those rocks from Mars. If they had stayed on Mars they would've probably evolved into alligators or even chimpanzees by now.

Sounds like the world underwent a cataclysmic change in climate in it's ancient past. More scientists adhere to catastrophism than ever before. And gradualism has gradually given way to punctuated equilibrium [the hopeful monster] in the evolutionary perspective. It's not creationism, but is much closer to it than when I was in high school 30 years ago. Velikovsky is not considered as heretical as he was when he published his work Worlds in Collision in 1950.

Thank God for this discovery! We'll finally put the "human cause" of global warming to rest!!!!! Of course, it will turn out that a Frenchman was there just a-cookin his dinner after searching for gold. Alas, he was from California and inadvertantly brought some flies with him in his raunch, smelly clothes.

How did they know this fly was a fossil?
Well, modern day flies have zippers.  This
fly was zipless, and thus ancient.

Much of the science explaining continental drift has developed since I was in school so I have little expertise.

However, if the continents drift relative to each other, then they must certainly drift relative to the axis of rotation of the earth. This means that the "seasons" which are experienced can vary on any given continent independently of the average temperature of the earth.

The more surprising result might be if it was determined that there had never been flies on a particular continent. I suppose that the 15 mya time frame suggests that Antartica was located at the south pole roughly where it is now.

1(one) Fly......
I don't suppose its possible wind currents swept the fly up to higher zones from somewhere else and deposited it there where it immedialtely froze NAH!... Heck they find spiders way high in the air colunm....regularly.. to be deposited in other CONTINENTS... why not flys...

finding the fly was dumb luck..?
Why not...

How do we know the fossil didn't come from mars like that rock they found a year or so back ? Maybe this is proof of extraterrestial life !!!!! ;-) ;-) ;-)

Seriously though the line :

It's just a tiny fossil of a fly that scientists found some 300 miles from the South Pole. But this fossil will help them: --figure out what life was like millions of years ago in ancient Antarctica and --help explain global changes in today's climate

Says it all.

Did anyone ever watch that old game show called liars club ? This is somehow related..........

The only fact will be they found a fly fossil in antartica.

But what will be taught as fact is all manner of extrapolation of personal views and agendas by "scientists" or at least by "scientists that are smart enough to only say the approved truth" the other kind don't count............

Sigh.....

Nice chart. Didn't know that million of years ago, "they" had little weather men with their stone tablets recording CO2 and temperature variations.

It's called ice,(VOSTOK antartica) containing microscopic bubble samples of the atmosphere.

PS. You might try reading the article on Coal strata as well. Amazing how CO2 content of the atmosphere affects the growth of vegitation, and the depostitation of carbonate deposits in sediments.

As far as temperature, isotope ratios serve as excellent proxies for temperature.

Now how can that be after all everyone "knows" that the earth is only 6,000 or so years old (/sarcasm)

..."what caused the temperatures in Antarctica to fall?"

Global COOLING? From the cigar smoke and the exhaust from the tiny SUV?
