"All of these discoveries not only puzzled the experts but also undermined the most fundamental doctrines of modern science." http://www.adguk-blog.com/2013/08/300-million-year-old-machinery-found-in.html The Voice of Russia and other Russian sources are reporting that a 300 million year old piece of aluminum machinery has been found in Vladivostok. Experts say a gear rail appears to be manufactured, and not the result of natural forces.
According to Yulia Zamanskaya, when a resident of Vladivostok was lighting the fire during a cold winter evening, he found a rail-shaped metal device which was pressed in one of the pieces of coal that the man used to heat his home. Mesmerized by his discovery, the responsible citizen decided to seek help from the scientists of Primorye region.
After the metal object was studied by the leading experts, the man was shocked to learn about the assumed age of his discovery. The metal artefact was supposedly 300 million years old, and the scientists suggested that it was not created by nature, but was rather manufactured by someone.
The question of who might have made an aluminum gear in the dawn of time remains unanswered.
The find was very much like a toothed metal rail, created artificially. It was like parts which are often used in microscopes, various technical and electronic devices.
Nowadays, finding a strange artifact in coal is a relatively frequent occurrence. The first discovery of this sort was made in 1851 when the workers in one of the Massachusetts mines extracted a zinc silver-incrusted vase from a block of coal, which dated all the way back to the Cambrian era, which was approximately 500 million years ago.
Sixty one years later, American scientists from Oklahoma discovered an iron pot which was pressed into a piece of coal aged 312 million years old.
Then, in 1974, an aluminum assembly part of unknown origin, was found in a sandstone quarry in Romania.
Reminiscent of a hammer or a support leg of a spacecraft, the piece dated back to the Jurassic era, and could not have been manufactured by a human.
All of these discoveries not only puzzled the experts but also undermined the most fundamental doctrines of modern science.
Another question that interests Russian scientists is whether the aluminum alloy is of Earthly origin. It is known from the study of meteorites that there exists extra-terrestrial aluminum-26 which subsequently breaks down to magnesium-26.
The presence of 2 percent of magnesium in the alloy might well point to the alien origin of the aluminum artefact. It could also be evidence of some past, unknown civilization on Earth. Nonetheless, further testing is needed to confirm this hypothesis.
It is the first such finding in coal made in Russia, according to anomaly researcher and biologist Valery Brier, who took microscopic samples of the aluminum for testing. Valery Brier performed X-ray diffraction analysis of the metal.
It showed very pure aluminum with microimpurities of magnesium of only 2-4 percent. Analysis was also conducted by Senior Fellow of the St. Petersburg Institute of Nuclear Physics Igor Okunev who confirmed the age of the material according to Natalia Ostrovsky
While exploring core samples (rock samples) that were raised from a 9-meter depth during the drilling of the seabed to support the bridge on a Russian island near Cape Nazimova, strange metal alloys were discovered that were "preserved" in the prehistoric sandstone (240 million years old).
The pieces of special alloys had an unusual composition, and were clearly not used in the drilling machinery.
Not so long ago in Russia a mechanical device was found in volcanic rock which was dated 400 million years before the current era (B.C.E)It was found on the remote Kamchatka Peninsula, 150 miles from the village of Tigil, by archaeologists at the University of St. Petersburg, among some very strange fossils. The reliability of the finds has been certified.
According to archaeologist Yuri Golubev, the find amazed experts, as it was some kind of a machine.
