Over 140 New Nazca Lines Have Been Discovered, And We Finally Have Clues To Their Use

Published

on

Scientists have discovered over 140 new geoglyphs known as Nazca lines: a mysterious, ancient cluster of giant figures etched long ago into the desert terrain of southern Peru.

These massive, sprawling representations of humans, animals, and objects date back in some cases 2,500 years, and are so large, many of them can only be identified from the air.

Now archaeologists from Japan’s Yamagata University report that a long-term research effort conducted since 2004 has uncovered 143 previously unknown Nazca geoglyphs – with one carved figure, which had eluded human detection, being discovered by artificial intelligence.

In all, the newly identified geoglyphs are thought to have been created between at least 100 BCE and 300 CE. While the purpose of these large motifs drawn by the ancient Nazca culture remains debated, we do at least know how they were constructed.

All of these figures were created by removing the black stones that cover the land, thereby exposing the white sand beneath,” the research team explains.

Previous hypotheses have suggested the Nazca society shaped the giant geoglyphs – some measuring hundreds of metres long – to be seen by deities in the sky, or that they may serve astronomical purposes.

In the new research, led by anthropologist and archaeologist Masato Sakai, the team analysed high-resolution satellite imagery of the Nazca region, as well as conducting fieldwork, and identified two main types of geoglyphs.

The oldest carvings (100 BCE to 100 CE), called Type B, tend to be less than 50 metres (165 feet) in length, while the slightly later effigies (100 CE to 300 CE), called Type A, span more than 50 metres, with the largest geoglyph discovered by the team measuring over 100 metres (330 feet).

The researchers think the larger Type A geoglyphs, often shaped like animals, were ritual places where people held ceremonies that involved the destruction of various pottery vessels.

By contrast, the smaller Type B motifs, were located along paths, and may have acted as way posts to orientate travellers – possibly towards a larger Type A ritual space where people would congregate.

Some of these Type B designs are really quite tiny, with the smallest of the new discoveries measuring under 5 metres (16 feet) – something that makes discovering the often faint lines a difficult task, especially when coupled with the enormous expanse of the Nazca desert region.

To that end, in a recent experimental collaboration with researchers from IBM that began in 2018, the team used a deep learning AI developed by the company, running on a geospatial analytics system called the IBM PAIRS Geoscope.

The learning network – the IBM Watson Machine Learning Accelerator (WMLA) – sifted through huge volumes of drone and satellite imagery, to see if it could spot any hidden markings bearing a relation to the Nazca lines.

The system found a match: the faded outline of a small Type B humanoid-like figure, standing on two feet.

While the symbolic meaning of this strange and ancient character is not yet clear, the researchers point out that geoglyph was situated near a path, so it may have been one of the hypothesised waypost markers.

In any case, it’s a striking, poetic kind of accomplishment: an almost unfathomably advanced thinking system created by modern humans enables the discovery of a yet unfathomable symbolic system created by ancient ones.

All told, the remarkable mystery of the Nazca lines is still far from being solved, but now that the Yamagata team and IBM have said they will continue working together to locate more of these ancient geoglyphs in the future, who knows just what – or whom – we’ll find next?

A summary of the ongoing research is available at the Yamagata University website.

Researchers Opened The Stomach Of This Perfectly-Preserved Dinosaur ‘Mummy’ To Find Its Last Meal

About 110 million years ago, a giant plant-eating Nodosaur gobbled down its last meal on Earth — and its stomach was preserved so well over time that scientists have now been able to determine what, exactly, its last meal was.

The remarkable specimen was first discovered in 2011 during a mining operation in Alberta, Canada.

The Nodosaur was found with its skin and guts intact and was altogether so well-preserved that it was referred to as a dinosaur “mummy.” A researcher involved in the study described the prehistoric specimen as having the best-preserved dinosaur stomach ever found to date.

A National Geographic video about the nodosaur, the best-preserved fossil of its kind ever discovered.

It took six years for Mark Mitchell, a technician at the Royal Tyrrell Museum of Palaeontology, to carefully dig out the dinosaur’s preserved skin and bones from the marine rock in which it had been encased. His efforts revealed a soccer ball-sized chunk of material left in the Nodosaur’s stomach.

The leaf fragments and other plant fossils were preserved down to the cells,” said David Greenwood, a biologist at Brandon University and co-author of the study.

The Nodosaur, or Borealopelta Markmitchelli, was an armoured giant. Despite its massive weight, which could be over a ton, the Nodosaur was a strict herbivore. And based on its stomach contents, its favourite vegetation was likely ferns.

A closer look at the nodosaur’s stomach contents.

After comparing its stomach contents with fossil leaves from the same time period and territory, researchers noted that the Nodosaur was a picky eater and preferred the soft leaves from certain types of ferns.

The lack of horsetails and rarity of cycads and conifers is surprising, given that these are very common in the surrounding flora,” said Caleb Marshall Brown, curator of dinosaur systematics and evolution at the Royal Tyrrell Museum of Palaeontology. “Even within ferns, it looks like Borealopelta may have had a preference for certain types of ferns while ignoring others.”

In total, researchers found 48 microfossils of pollen and spores, moss and liverwort, 26 club mosses and ferns, two flowering plants, and 13 conifers.

The study also noted that were pieces of charcoal in the Nodosaur’s stomach. This turned out to be consistent with its time period, as forest fires were a common occurrence during the early Cretaceous period and ferns, which were low to the ground, could survive.

This nodosaur is among the best-preserved dinosaur specimens known to date.

Researchers estimated that a fire had indeed ravaged the grazing area of the Nodosaur about six months before it ate its last meal in the spring or summer.

“The discovery of charcoal together with a fern-filled stomach… suggested Borealopelta was likely a keystone herbivore that shaped the landscape by its grazing, and that it also grazed on the ferns growing in open areas created by wildfires,” Greenwood said. “That is so cool.”

The study was published in the journal Royal Society Open Science in June 2020.

Island In The Clouds: Is Mount Roraima Really A ‘Lost World’ Where Dinosaurs May Still Exist?

Island In The Clouds: Is Mount Roraima Really A ‘Lost World’ Where Dinosaurs May Still Exist?

Deep within the rainforests of Venezuela, a series of plateaus arise more than 9000 feet (2743 meters) off the ground. From above, they look like islands in the sky. These are the Tepuis (a Pemón Indian word for mountain), the most famous of which is called Mount Roraima. The Tepuis are so unique in their geography that thousands of plant species exist nowhere else on the planet except on these plateaus. The mystical mountains fascinated explorers and writers for centuries, most notably Sir Arthur Conan Doyle who described an ascent of Mount Roraima in his 1912 novel The Lost World. In Doyle’s novel, a group of explorers found that dinosaurs and other extinct creatures were still alive and well on the remote plateaus. Some people today still believe this to be a real possibility.

The Real Lost World

Once impenetrable to all but the Pemón indigenous people, Mount Roraima really was a lost world. The mountain plateaus were already established when South America was linked with Africa to form the supercontinent Gondwana, meaning they were first formed perhaps 400 to 250 million years ago. During this time, molten rock forced its way up through cracks in the sandstone landmass. At the same time, wind and water swept across Gondwana to erode the raised highlands into mountain ranges. The region would come to look much like it does now around 20 million years ago.

Because the Tepuis have been isolated for so long atop their high, lonely plateaus, the flora and fauna of the Tepuis provide an organic illustration of the processes of evolution. It is guessed that “at least half of the estimated 10,000 plant species here are unique to tepuis and surrounding lowlands. New species are still being discovered.” (George, 1989). Although all of the Tepuis have been climbed, only a few have been extensively explored. Could this mean that supposedly extinct species, even dinosaurs, may still exist atop these remote plateaus?

The Roraima plateaus are so remote and so unique that it is not difficult to imagine Sir Arthur Conan Doyle creating a world alive with prehistoric plants and dinosaurs in his novel The Lost World. Doyle was fascinated with the accounts of British botanist Everard Im Thurn, who climbed to the top of Mount Roraima in December 1884.

Ascending Mount Roraima in 1989 for the National Geographic Society, German explorer Uwe George said, “None of us who followed Im Thurn to Roraima have found primordial creatures or their fossil remains there, but the terrain is so difficult that only a fraction of the Tepui’s 44 square miles has so far been explored” (George, 1989). Since his writing, more of Mount Roraima has been investigated and, unsurprisingly, no traces of dinosaurs have been found.

Sacred Ground

Prior to the arrival of Europeans, the natives of Venezuela viewed the tepuis as having special mythical significance. According to the Pemón Indians, Mount Roraima is “the stump of a mighty tree that once held all the fruits and tuberous vegetables in the world,” however it was “felled by one of their ancestors, the tree crashed to the ground, unleashing a terrible flood” (Naeem, 2011). They believed that if a person ascended to the top of the tepuis, he or she would not come back alive.

A ‘Crystal Mountain Covered with Diamonds and Waterfalls’

Climbing the Tepuis is exceedingly difficult and is made all the more so by the frequent rains that makes the rocky footpaths slippery and muddy. The first European explorer to write about the Tepuis was Sir Walter Raleigh in 1595. He wrote of a crystal mountain covered with diamonds and waterfalls:

“There falleth ouer it a mightie riuer which toucheth no parte of the side of the mountaine but…falleth to the grounde with a terrible noyse and clamor, as if 1000 great belles were knockt one against another…but what it hath I knowe not, neyther durst he or any of his men ascende to the toppe of the saide mountaine, those people adioyning being his enemies (as they were) and the way to it so impassible.” (Raleigh quoted in George, 1989).

There is a good chance that Sir Raleigh was describing Angel Falls, so named for the mid-20th century American Jimmie Angel who was the first person to fly over the area. Angel Falls were recently featured in Disney’s Up, where the falls are referred to as Paradise Falls.

While today’s travellers may not stumble upon dinosaurs and other prehistoric creatures, they will be able to see black frogs and tarantulas that exist nowhere else on the planet. It is believed there are many other species unique to Roraima that are yet to be discovered.

Scientists Discover 400-Year-Old Greenland Shark Likely Born Around 1620

Greenland sharks are now the longest-living vertebrates known on Earth, according to scientists.

Researchers used radiocarbon dating of eye proteins to determine the ages of 28 Greenland sharks, and estimated that one female was about 400 years old. The former vertebrate record-holder was a bowhead whale estimated to be 211 years old.

As lead author Julius Nielsen, a marine biologist from the University of Copenhagen, put it: “We had our expectations that we were dealing with an unusual animal, but I think everyone doing this research was very surprised to learn the sharks were as old as they were.”

Greenland sharks are huge and can grow up to 5m in length. Yet, they grow at just 1cm a year. They can be found, swimming slowly, throughout the cold, deep waters of the North Atlantic.

The team believes the animals only reach sexual maturity when they are 4m-long. And with this new, very lengthy age-range, it suggests this does not occur until the animals are about 150 years old.

The research was made possible, in part, by the atmospheric thermonuclear weapons tests conducted during the 1960s, which released massive amounts of radiocarbon that were then absorbed by organisms in ocean ecosystems. Sharks that showed evidence of elevated radiocarbon in the nucleus of their eye tissue were therefore born after the so-called “bomb pulse,” and were younger than 50 years old, while sharks with lower radiocarbon levels were born prior to that, and were at least 50 years old or older, the study authors wrote.

The scientists then calculated an age range for the older sharks based on their size, and on prior data about Greenland sharks’ size at birth and growth rates in fish.

According to the results of the analysis – which has a probability rate of about 95% – the sharks were at least 272 years old, and could be as much as 512 years old (!) with 390 years as the most likely average life span, according to Nielsen.

Oldest Shark in the World – 512 Year Old Greenland Shark

But why do Greenland sharks live so long?

Their longevity is actually attributed to their very slow metabolism and the cold waters that they inhabit. They swim through the cold waters of the Arctic and the North Atlantic at such a sluggish pace that has earned them the nickname “sleeper sharks.” Seal parts have been found in their bellies, but the sharks move so slowly that experts have suggested that the seals must have been asleep or already dead when the sharks ate them.

The slower you go, the farther you will be.

Viking Grave Found Under The Floorboards Of A Home In Norway

Published

A Norwegian couple made an unusual historic discovery during renovations of their home. They found a number of Viking era artifacts, and now archaeologists believe that they have found a Viking grave, right there, under their floor. Experts are currently carrying out a survey of the site and the grave is being hailed as a very significant find.

The couple made the find while tearing up some floorboards in their family home in Seivåg near Bodø in Northern Norway. They were laying insulation when they came across some strangely shaped rocks.

Naturally, they were curious, and then they saw something round glinting in the light. They knew that it had to be old because the house had been built in 1914 and the floorboards had not been moved since. The house has been in the same family for over a century.

This Valuable Viking Grave is Missing Something Important
Viking Burial Under the Boards

Based on the shape of the object “they first believed it was the wheel of a toy car” according to The Local. The couple only later realized that what they had found could be something historic.

After some further digging, the couple found an iron axe head and some other metallic objects, that were all obviously old. ‘It wasn’t until later that we realized what it could be” Mariann Kristiansen, one of the owners of the house, told The Local.

The couple contacted the local authorities and experts from the local Nordland county government came to inspect the finds. Martinus Hauglid told the couple that they had most likely found a grave from the Iron Age in Norway. This was the era when the Vikings ruled in Scandinavia and terrified most of the known world.

The archaeologist told The Local that the couple had found an “axe dated between 950 and 1050 AD.” The bead of glass, which was revealed to be blue dates from the same period.

Viking Cairn

It is believed that the stones found underneath the flooring came from a burial. The stones were likely part of a cairn. In this type of burial, a mound of stones and rocks are erected over the deceased which was a very common burial practice in the Iron Age.

A number of similar cairns were found in the Lendbreen Mountain Pass in Norway when a glacier melted. This was an important trade route in the Middle Ages.

Martinus congratulated the couple on their find and stated that they had done a good job, by reporting things so soon. The archaeologist said that it was the first instance of a Viking grave being found under a private dwelling in his 30 year career.

Archaeologists have begun an investigation of the grave. Forbes reports that under Norwegian Law any human artifacts or “activity before 1537 are automatically preserved.” The items found by the couple have been transported to a museum for conservation and safekeeping.

End of the Viking Age

Martinus is quoted by Forbes as stating that the finds under the floorboards date back to a time “when Norway transitioned to Christianity to become one kingdom.” This was the time when kings like Olaf Tryggvason, attempted to dominate the many chiefdoms and create a centralized state.

Some of these monarchs sought to impose Christianity on the pagan Norse as part of their efforts at state-building and this led to many civil wars. The grave could help researchers to better understand this crucial period in Norwegian history which saw the demise of the Viking Age.

It appears that the original builders of the house, over a century ago, were not aware that they were building a private residence on a grave. It is quite possible that they unearthed items and simply discarded them. This raises the possibility that some Viking-era grave goods were lost or destroyed during the construction of the family home.
