Stone disk found in coal mine in Russia

In 2015, a stone disk was found in coal mine somewhere in Russia. Is it a UFO that crashed on Earth?

Scott C. Waring explains:

I believe what they have found is a UFO drone ship. These smaller drones are used as scouts for keeping larger ships safe. Often a UFO will have these small scouts or even smaller baseball size orbs rotating around the UFO like a protective shield. Many such UFO disks have been found around the world, always heavy and appear to be made of stone. However I do not believe its really stone, but a condensed nano bot micro material that strengthens the UFO like stone, but actually is a complex network. I believe if we looked at its material under an electron microscope, we would find evidence of micro alien tech.

News states:

A mysterious boulder resembling a flying saucer was unveiled on Sunday after it was unearthed at a coal mine in the Belovo District, Kemerovo at the end of January. The disc is 1.2m (3.9ft) in diameter and weighs approximately 200kg (441lb).
