5 Ancient Weapons Archaeologists Can't Explain

Flint tools and weapons are a common find for archaeologists, with many being left behind by prehistoric civilizations; however, in Spain, researchers have discovered a set of incredible weapons made of rock crystal.

Between 2007 and 2010, researchers from the University of Granada, the University of Seville and the Spanish Higher Research Council excavated the megalithic tomb of Montelirio Tholos in Southwestern Spain.

The massive burial site sits 143 feet long with eight different sectors and includes a 128-foot-long corridor leading to the main chamber that is more than 15 feet in diameter. Dating back to at least 3000 BCE, the remains of around 25 individuals were found during the excavation and analysis suggested that at least one male and several females amongst them died from ingesting poison. The remains of the women were found in one of the chambers, seated in a circular fashion and next to the bones of who seemed to be the chief.

Nearby there were 19 rock crystal arrowheads found together in a cluster which led researchers to suspect that they were a spiritual offering. It is believed that rock crystal during this time may have had symbolic significance and these prehistoric cultures would have used it for vitality, magic powers and connections with ancestors.

The rock crystal dagger sat on its own in a separate chamber with an ivory hilt and sheath, measuring nearly 8.5 meters long and looking similar in shape to other stone daggers of the period...

One of the Greatest Mysteries of Human Evolution - The Extinction of Homo Erectus

In this video, we'll take a look at one of the greatest mysteries of human evolution: the extinction of Homo Erectus. Homo Erectus is one of the most significant developments in human history and it's still a mystery why they disappeared. In this video, we'll explore the evidence and try to answer the question: why did Homo Erectus go extinct?

Homo erectus was a species of early human that lived between 1.8 and 0.2 million years ago. Although they were contemporaries of Homo sapiens, they ended up becoming extinct sometime around 300,000 years ago. What caused their extinction is still a mystery, and researchers are still looking for answers. in this video, we'll explore some of the theories about what might have caused the extinction of Homo erectus.

The Evolution of the Heart

Throughout history many different cultures across the world have concluded that the heart is the most important organ in the body. Often thinking the heart was more akin to a brain with blood vessels sending messages around the body. And although this is wrong, Its easy to see where the fascination with this organ in particular comes from, its the Centre of an incredibly complicated network of tubes meandering through almost every part of the body and is absolutely crucial for almost every function in the body. So How did such a complex mechanism evolve with multiple parts working together evolve? and how did animals get by without something so important for life, before the evolution of the heart?

Scientists Found a Dinosaur's Face, Complete With Its' Skin

In 2011, archaeologists uncovered one of the most — if not the most — pristine dinosaur fossils yet: a near-whole ankylosaur, complete with its jagged spikes, most of its limbs, armor coating, and some of its guts and stomach contents. The most amazing detail, though? Its uncannily preserved face and skin.

It took Mark Mitchell, a technician at Royal Tyrell Museum, an absurd 7,000 hours and nearly six years to meticulously exhume the fossil by delicately chipping away at the surrounding stone. For his efforts, he had the newly discovered specie of nodosaur — a type of ankylosaur — named after him: Borealopelta markmitchelli.

"During preparation, I would piece together the blocks like a puzzle, and the animal started to really take shape," Mitchell said in a new interview with Ars Technica, describing the painstaking process.

"Right before Christmas one year," he continued, "I had pieced together both sides of the neck and the head, and you could really appreciate the impressiveness of the specimen and that this was a living creature with astounding preservation."

That's a holotype for the ages. The museum's curator, Donald Henderson, told Ars that he wagered it was a literal "one in a billion" find.

World Building

Researchers were able to get their hands on the remarkable specimen in 2017 after Mitchell had finished preparing it, and they've since published a series of impressive studies.

One such study led by Caleb Brown, a curator at Royal Tyrell, examined the bone structure known as osteoderms found on ankylosaurs, which in less freakishly preserved specimens, usually fall out of place.

These ones remained in their natural spots, however, and Brown measured all 172 of them.

"Many armored dinosaur skeletons are preserved disarticulated, meaning their bones are all jumbled up," Brown told Ars. "Having the osteoderms preserved in life position in this specimen, and other specimens, can give us clues as to how to reconstruct those specimens where the position of the armor is less clear."

His study's big takeaway? The suggestion that those iconic spikes aren't actually meant to stave off predators, but to show off in order to attract mates.

Another study on the specimen led by Brown and his colleagues posits that the Boreapelta used a form of camouflage known as countershading, which heretofore hasn't been observed in creatures of its size, i.e. big ones. As Ars notes, the fact that such a formidably armored dinosaur also had to employ camouflage to survive may imply that the Cretaceous period was even more cutthroat than once thought.

And the most recent study, published this month, offers an extremely rare look at the diet of dinosaurs like the Borealopelta.

So while its fate may be set in stone, the Borealopelta continues to shape our understanding of the almost alien world of the dinosaurs.

World’s Deepest Shipwreck Discovered Four Miles Underwater in the Philippines

The U.S.S. Samuel B Roberts, also known as the “Sammy B,” was discovered in the Philippine Sea at a depth of 22,916 feet last week by a team of explorers. The wreck is the deepest ever found, per the Associated Press. The Navy confirmed the wreck site in a statement on Monday.

Explorer and former naval commander Victor Vescovo of Caladan Oceanic Expeditions found the ship along with EYOS Expeditions, a U.K.-based exploration company.

“It was an extraordinary honor to locate this incredibly famous ship, and by doing so have the chance to retell her story of heroism and duty to those who may not know of the ship and her crew’s sacrifice,“ Vescovo says in a statement.

The Sammy B was the first ship named after Coxswain Samuel Booker Roberts, Jr., who was killed in World War II during the Battle of Guadalcanal in 1942, per the Navy. Roberts took part in a mission to rescue a company that had been surrounded by Japanese forces, steering his boat directly into their fire to provide time and cover for the rescue. His ship was hit and he was mortally wounded in the process.

The ship bearing his name, a John C. Butler-class destroyer (a type of escort ship), was commissioned in 1944 and was sunk by Japanese forces during the Battle of Samar later that year. Two other ships, another destroyer and a frigate, were also later named the U.S.S. Samuel B. Roberts.

During the Battle of Samar, a “small US naval force successfully defended against the vastly superior Japanese Center Force, consisting of four battleships, six heavy cruisers, two light cruisers and 11 destroyers—including the largest and most heavily armed battleship ever constructed, the Yamato,” writes EYOS Expeditions in a Facebook post. The Sammy B damaged the Japanese fleet and delayed it for so long that it retreated, but the destroyer took a hit from the Yamato and sank. Eighty-nine people aboard the Sammy B died and 120 were saved, per the Associated Press. The rescued crew members were forced to cling to wreckage in the water for up to 50 hours, according to BBC News’s Jonathan Amos.

“The Sammy B bore evidence of the incredible, ferocious fight that she waged against the cream of the Imperial Japanese Navy,” Vescovo tells Amos. “There were shell holes. She obviously had taken a massive hit from a battleship on her stern quarter [the rear of the boat], with it basically blown apart.”

Vescovo tells BBC News that he was surprised they were able to locate the ship because there was so little debris pointing them in the right direction. Despite the ship being broken into two pieces, it was relatively intact, he tells the outlet. The team was searching for several vessels, and the Sammy B was the smallest.

The depth that the Sammy B’s wreckage was found at is particularly extreme—98 percent of the world’s oceans are shallower than the nearly 23,000 foot depth of its resting place, according to BBC News.

“Using a combination of detective work and innovative technology, everyone has pulled together to reveal the final resting place of this tenacious ship,” Kelvin Murray, expedition leader and director of Expedition Operations & Undersea Projects for EYOS, says in a statement. “It’s been challenging, thrilling and poignant expedition, one that recognizes the ships and sailors from all nations who fought so hard during this battle.”

The team discovered the U.S.S. Johnston last year in the Philippine Sea, which, at over 21,000 feet, was previously the deepest wreck ever discovered.

“At that depth, there’s so little oxygen that you don’t get near as much biological growth on the wrecks,” Vescovo tells BBC News. “So they can appear very much like they did when they were fighting back in 1944.”

This Painting Is More Dangerous Than It Seems. Here's Why.

This piece is called Flaming June by British painter, Frederic Leighton. It’s now one of the most famous paintings in the world, but it hasn’t always been that way. When you first lay your eyes on this beautiful painting, you may think her life has been easy, but this couldn’t be further from the truth. She’s been forgotten for decades, abandoned behind a false panel of a chimney mantel, stripped from her original opulent frame, thrown in the back of a junk shop and rejected by countless art collectors. It was purchased for £60 in 1962 and is now worth millions. The sitter for the painting is Dorothy Dene, born Ada Alice Pullen. Dorothy posed for many of Leighton’s paintings, which is why she is now referred to as his muse. Dene and Leighton’s relationship was cryptic and complicated. What’s for sure is that, together they created one of the most iconic paintings of all time.
