At first glance it looks like, well…an oversized boulder, the same colour as the rest of the surrounding rocks, that has been heavily eroded to give a smooth disc-like appearance.

But an established team of paranormal researchers in Russia called Kosmopoisk are convinced that the rock's resemblance to the shape of a mythical flying saucer mean it must have originated in space.

Local reports in Russia said the area where it was found - Medveditskaya Ridge, in Zhirnovsky district, near near Volgograd, Russia, was reknowned for UFO sightings and paranormal activity.

The four-metre across cracked "disc" was found last week according to Russian website bloknot-volgograd after Vadim Chernobrov, a famous paranormal investigator in Russia, and his team set out to the area, where they said they had previously discovered smaller ones of one to two metres in size.
