The scientists saw the fossil stumps in the Rain Forest in Arctic Norway. Dense forest with trees as tall as 12 feet and trunk wide and curved leaf branch with extensive forests near the equator like at 280 million years ago.
These forests not only as one of the oldest forests in the world but this forest also has a large distribution to the reduction of carbon dioxide in atsmosfer from time to time.
During the Devonian Period (416 million to 358 million years ago) large trees growing in the earth around the time that carbon dioxide in atsmosfer dropped signitifkan. Scientists see this as evidence that the forest trees in this forest has an important role in reducing CO2 from atsmosfer. Trees used for berfotosentesis greenhouse gases and form a sweet food. Contributing to global cooling event that occurred during the Devonian Period.
The latest discovery of the Ancient Forest located in the Svalbard group of islands in Norway in the Arctic Ocean attract the attention of Chris Berry and Cardiff University. Berry heard of the existence of this ancient forest of German peers who work at the site and immediately wanted to investigate the existence of the ancient forest.
Older than expected
Fellow Berry, John Marshall of Southampton University in calculating the age of the forest from extracting the spores of the rock and comparing them with the other spores from a similar place. They found that the fossilized forest was actually 20 million years older than previous estimates. Marshall and Berry realized that they were dealing with something that is "right from the beginning of the forest ecosystem," said Berry.
They suspect that the trees were originally grown in the basin with a width of 0.6 miles (1 kilometer) and a length of 3.1 miles (5 kilometers). Although the forest area is only a few square meters, but fossil remains in this place looks on the surface.
Parailmuwan investigate investigating three small fields in Svalbard where the fossil material visible above the ground, and many more that were found around the cliffs nearby. "On the cliffs there are many layers of fossil tree" said Berry told LiveScience.
CO2 reduction
Before shifting continents carried northern jungle by a few thousand miles, a lot of forest grows near the Equator. But the Ancient Forest Svalbard do not resemble modern forests in general, ancient trees that appear in 380 million years ago most of lypcopsyd also known as "Club moss" Lycopsids produce leaves with a single vein and reproduce by spores. There are probably about 1,200 lycopsids are still alive today.
In Svalbard, Lycopsids grow to a height of about 13 feet (4 meters) and will be more stringent in containers with a gap of about 0.7 feet (20 cm) between one tree to another tree. The trunk will widen slightly at the bottom with some of them holding a diamond or oval shaped pattern. Tree "Scrub" Carbon dioxide Darui atsmosfer by absorbing through fotosentesis and these forests are likely to be absorbed more CO2 than any other living plants smaller covered planet.
In a statement, Berry describes the appearance of the trees on earth as the most likely cause of the decline of carbon dioxide in atsmosfer during the Devonian period, when CO2 plummeted from approximately 15 times that of the current one.
Early diversity
Svalbard forest is not the only ancient forests on earth. Berry had previously been analyzed other ancient forests like the Ancient Forest Gilboa, New York but with a different composition of the forest. Giant-pandan pandanus tree in the forest is made of thousands of roots and few there lycopsids.
Interestingly trees in the Ancient Forest Gilboa is absolutely nothing in the Ancient Forest Svalbard. "This shows that more than one group tree is not the same forest that forms between the forest one with the other forest on Earth," said Berry told LiveScience.
