In China, found fossil forests 400 million years of age
Scientists routinely detect the remains of ancient plants and animals that can tell us a lot about how to build and develop life on this planet long before the development of our civilization. And recently in China were found fossils of one of the oldest (known at the moment) forests. Age fossil is about 400 million years. And they can help scientists understand what they are interested in a long time.
When there was an ancient forest
According to the publication Current Biology, the forest was discovered near the town of Xinhai in Anhui Province during excavations on the territory of one of the mines. This place has been a long time for scientists "lure".
Jianchuan Mine has been in development for several years, and in this area has always worked diggers and miners Brigade - says Deming Wang from Peking University. Excavations in such places often are beneficial to our research. When the diggers and miners completed their work, we will examine the walls of mines and looking deep in the earth the remains of ancient fossils.
Reconstruction of the appearance of the ancient forest, discovered in China
Scientists believe that the observed forest existed during the Devonian period, which lasted from 419 to 2 358, 9 million years ago. Interestingly, this period is primarily the fact that it was then that on our planet there were the first trees, and by the middle of the Devonian period were formed and the first ferns.
What trees grow in the ancient forest
Among them are the trees that formed the forest that period usually were lycopsids sigillaria plant, reaching a height of 20-25 meters. Or trees species Guangdedendron micrum. These trees are somewhat reminiscent of palm trees up to 2 meters. However, recently discovered by the forest did not look quite right.

As scientists say, the forest grew on the coast of the river, which is often "waterlogged" trees. Therefore, the terrain here was pretty swampy. In addition to the already mentioned palmovidnyh Guangdedendron micrum, scientists have discovered the remains of ancient crinoids, crustaceans conchostracans and ancient fish.
The high growth density and low height of the trees make the forest look like a sugar cane field. In this case, the trees grew here, obviously, a fairly large group.
The researchers say that the discovery will help give an idea of how during the Devonian period, there was a rapid drop in carbon dioxide in the atmosphere of ancient Earth.
