The tree is grown on the surface of the planet is about 375 million years ago, and first examined the device, according to an article published in the journal PNAS.
“Before we can find the petrified tree trunks, already filled with sand, which prevented us to understand how they work from the inside. The trunk of an ancient tree, which we found in Xinjiang, was of great size, and perfectly preserved in a kind of “packaging” of volcanic silica that has allowed us to consider every cell,” says Chris Barry (Chris Berry) from Cardiff University (UK).
Today scientists believe, the first trees appeared in the middle Devonian period, about 400 million years ago.
What looked like these first trees, remains a mystery to scientists — we only know a small number of “petrified forest”, a special type of deposits that time, which preserved the full trunks and root systems of these trees, which were underground due to the fact of ash or lava.
Their study shows that the flora of that time was represented by a very bizarre objects — the role of leaves in them performed a special photosynthetic bark, and they were like dwarf trees with modern tundra.
