Historians Studying an ‘Ancient’ Scottish Stone Circle Learn It Was Built in the 1990s

In December 2018, Scottish historians and archaeologists learned of a newly discovered ancient recumbent stone circle on local farmland in Leochel-Cushnie, Aberdeenshire. But this week, their excitement fizzled: According to The Guardian, a former owner of the farmland contacted the historians and admitted the structure was a replica stone circle built in the mid-1990s.

Late last year, local officials inspected the formation and determined that its dimensions, though 10 feet smaller than similar recumbent stone circles, were in line with others found in Scotland. Historic preservationists were thrilled with the discovery. “It is rare for these sites to go unidentified for so long, especially in such a good condition,” Neil Ackerman, a historic environment record assistant at the Aberdeenshire Council, told Aberdeen's Press and Journal.

Recumbent stone circles (RSCs) are specific to the Aberdeenshire region in northeast Scotland as well as southwest Ireland, and they often date back 3500 to 4500 years. RSCs are traditionally found with one large stone slab laid flat on the southern side of the formation, flanked by two tall stones, and made a circle by other stones. RSCs are thought to have served as windows or manmade horizons for specific moon patterns (such as the periodic standstill moon), though they may have been used for rituals and burials.

This one likely served none of those purposes. While it's unclear why the landowners built the stone circle and why they are now coming clean, the truth about its recent vintage was “disappointing,” Ackerman told The Guardian. But, he said, it “adds an interesting element to its story. That it so closely copies a regional monument type shows the local knowledge, appreciation, and engagement with the archaeology of the region by the local community.” He noted that the council is always open to reports of any modern constructions that mimic these ancient monuments.

Middle School Student Discovers Megalodon Tooth Fossil on Spring Break

A few million years ago, the megalodon was the most formidable shark in the sea, with jaws spanning up to 11 feet wide and a stronger bite than a T. Rex. Today the only things left of the supersized sharks are fossils, and a middle school student recently discovered one on a trip to the beach, WECT reports.

Avery Fauth was spending spring break with her family at North Topsail Beach in North Carolina when she noticed something buried in the sand. She dug it up and uncovered a shark tooth the length of her palm. She immediately knew she had found something special, and screamed to get her family's attention.

Her father recognized the megalodon tooth: He had been searching for one for 25 years and had even taught his three daughters to scour the sand for shark teeth whenever they went to the beach. Avery and her sisters found a few more shark teeth that day from great whites, but her megalodon fossil was by far the most impressive treasure from the outing.

Megalodons dominated seas for 20 million years before suddenly dying out 3 million years ago. They grew between 43 and 82 feet long and had teeth that were up to 7.5 inches long—over twice the size of a great white's teeth. They're thought to be the largest sharks that ever lived.

Megalodon teeth have been discovered on every continent except Antarctica, but they're still a rare find. Avery Fauth plans to keep her fossil in a special box at home.

Stonehenge Builders Likely Descended From Immigrants, Genetic Analysis Says

There's a lot we don't know about Stonehenge, but until recently, the structure was thought to have been built by hunter-gatherers native to what's considered England today. A new study disputes that theory. As IFL Science reports, Stonehenge was likely the the work of Turkish people who migrated to Britain 6000 years ago and their descendants.

In the new report published in the journal Nature: Ecology & Evolution, scientists from London's Natural History Museum and University College London explain how they analyzed the DNA from the remains of dozens of people who lived in Britain between 8500 BCE and 2500 BCE.

The results contained fewer native British genes than expected: Researchers found that when the people whose bones they studied were alive, most of Britain's hunter-gatherer population had already been replaced by farmers from the Aegean region.

Roughly 6000 years ago, people from what is now Turkey traveled across Europe and settled in Britain. In addition to reshaping the British gene pool, the new group also introduced agriculture to the area. Archaeologists have long debated whether farming is something that was brought to Britain by a different culture or if native hunter-gatherers gradually adopted it on their own.

"The transition to farming marks one of the most important technological innovations in human evolution. It first appeared in Britain around 6000 years ago; prior to that people survived by hunting, fishing and gathering," study co-author Mark Thomas said in a press release. "Our study strongly supports the view that immigrant farmers introduced agriculture into Britain and largely replaced the indigenous hunter-gatherer populations."

That means Stonehenge, the first part of which was constructed around 3000 BCE, was likely the work of people who were culturally and genetically closer to ancient Aegeans than native Britons. But how they moved the 25-ton stones to their current location and for what purpose remains a mystery.
