The Voice of Russia reported a man from the Russian city of Vladivostok found a metal detail stuck to a piece of coal. The object comes in a "distinctive shape which was reminiscent of a modern tooth-wheel."
The man was lighting fire to heat his home when he spotted the odd object. Without naming the man, the 'Voice' reported he sought the help of "scientists of Primorye region" to study his find. The scientists reportedly said the object was man-made and it was supposedly 300 million years old.
The technology to craft the metal detail found by the man did not exist on Earth at the time of its supposed manufacture. The material found in the object, particularly the 2 per cent magnesium, prompted speculations that the object could not have been of Earthly origin.
"After the discovery came public, conspirators were quick to dub it 'a UFO tooth-wheel.' Russian scientists, however, do not jump to conclusions and will run further tests to learn more about the strange artifact," the 'Voice' report says.
