A skeleton with an unusual-shaped skull has been unearthed at a site known as Russia’s Stonehenge.

When images of the remains were first published, UFO enthusiasts were quick to claim that they were a sign that extraterrestrials had visited the Earth.

But archaeologists have revealed that the bones belong to a group that was created almost 2,000 years ago and had an elongated skull because it was outside the tribal tradition.

A skeleton with an unusually shaped skull (pictured) has been unearthed at a site known as Russia’s Stonehenge. UFO enthusiasts were quick to claim it was a sign that aliens visited Earth when it was first found.

The remains were found in Arkaim, near ChelyaƄinsk, in central Russia, a settlement dating back almost 4,000 years.

The woman is believed to have belonged to a group that was part of what is now Ukraine.

Researcher Maria Makuroʋa confirmed to the Russian news agency TASS: “We have found a well-preserved skeleton.

“I would not exclude the possibility that the skeleton belongs to one of the three groups that existed in the territories of what is now Ukraine, Kazakhstan and southern Russia.

‘Her skull became longer because the tribe made it by tying her children’s heads with a pig. It was clearly a tradition in the triƄu.

Archaeologists have revealed that the bones (pictured on the left) belong to a group that was created about 6,000 years ago and had an elongated skull (shown on the right) because it was outside the tribal tradition.

The remains were found in Arkaim (shown with a red marker) near ChelyaBinsk, central Russia. The site is generally dated to the 17th century BC, although some experts think it could have been created in the 20th century BC.

THE ANCIENT SITE OF ARKAIM

Arkaim is located in the Southern Urals in Russia and is believed to date from the 17th century BC.

The 20,000 square meter (220,000 square foot) settlement was protected by two circular walls before being burned and abandoned.

It had a central square surrounded by two circles of houses separated by a street.

Historian KK Ƅystrushkin compared the site to Stonehenge in 2003, saying that the years allowed ancients to study the stars.

However, this interpretation is not universally accepted.

She declined to comment on speculation that extraterrestrial visitors were being attributed, saying that they were currently still working on theories about why the trio had the tradition, but they didn’t have anything definitive yet.

The skeleton is believed to date from the 2nd or 3rd century AD, making it considerably younger than the site.

It is just another of the mysteries unearthed at the spectacular Arkai site known as Russia’s Stonehenge, believed to have been built in the 17th century BC.

Some believe that, like its 5,000-year-old English counterpart, it was used to study the stars.

But Arkaim is believed to be more advanced.

Stonehenge allows observations of 10 astronomical phenomena using 22 elements, while Arkai allows observations of 18 phenomena using 30 elements.
