UFO watchers are in a tizz over the discovery of an ancient skeleton with an elongated skull that resembles an ALIEN.

The humanoid skeleton was unearthed from a site known as Russia’s Stonehenge and it is being heralded as proof that aliens visited Earth thousands of years ago.

However, archaeologists don’t share the same view as alien hunters, insisting that the skeleton belonged to a female from a tribe that used to bind the head to make it grow out of shape.

Researcher Maria Makurova told Russian news agency TASS: “We have found a well preserved skeleton.

“I would not exclude the possibility that the skeleton belongs to a woman from the Sarmati trible that lived in the territories of what is now modern day Ukraine, Kazakhstan and southern Russia.

"Her skull was elongated because the tribe did so by tying up the heads of their children with rope.

“It was clearly a tradition in the tribe.”

But believers in life on other planets claim that if this was the case, it was simply a way of mimicking the elongated skulls of the alien visitors.

Makurova said that archeologists were still working on theories as to why the tribe had the skull-lengthening tradition, but had so far not come up with a reason.

Scientists who exposed the photographs say they believe that the body, that was discovered at Arkaim, did not date back as far as the age of the site, that originated in 4,000 BC.

They believe the bones in fact date back to around 200-300 AD - making them less than 2,000-year-old.

The Akraim archaeological site was discovered in 1987.
