On the Central Plateau in the Andes, scientists have found a giant fossil tree. The age of the find, according to preliminary calculations, can be estimated at 10 million years.

According to scientists, this tree grew in the Miocene era, when a humid tropical climate was observed on the territory, in contrast to the current one – cold and arid. The discovery was made by specialists from the Smithsonian Institute for the Study of the Tropical During the study of wood fossils, scientists found several contradictions. According to previously compiled paleoclimatic models, the climate in this region has not undergone such dramatic changes. An analysis of the artifact's pollen and wood shows that the Andes ecosystem and climate were then more humid. In the Miocene period, the plateau height reached 2 kilometers, and now it is 4 kilometers above sea level. At the same time, it is interesting that the structure of the found wood is similar to that which is present in modern tropical plants. At the same time, scientists have no doubt that the tropics in this region did not exist for long and the climate was changing very rapidly, and the tectonic uplift was accompanied by sharp impulses.
The rise of the Andes influenced the climate of South America. At the same time, no connections between these geological events, plants and environmental conditions have been identified. Scientists believe that global warming, which is observed on Earth today, by the end of the century will bring the climate back to the region that was observed 10 million years ago. Scientists intend to take into account all the discrepancies when drawing up a climate model of the world of the future.
