Archaeologists from St. Petersburg found on the Kamchatka Peninsula, fossils, which are components of a mechanism. The Russian archaeologists shared the results of the discovery with their colleagues from the United States and the latter confirmed that the fossils are apparently the components of a plant.

The experts believe that the mechanism has been able to sustain for such a long time (about 400 million years) as it lied into a swamp. In favor of this hypothesis, the fact that the objects had turned into fossils within a relative short period - in geological terms. The researchers speculated that the mechanism found could be of extraterrestrial origin.
