Five ice-age mammoths unearthed in Cotswolds after 220,000 years

Five ice-age mammoths in an extraordinary state of preservation have been discovered in the Cotswolds, to the astonishment of archaeologists and palaeontologists.

The extensive remains of two adults, two juveniles and an infant that roamed 200,000 years ago have been unearthed near Swindon, along with tools used by Neanderthals, who are likely to have hunted these 10-tonne beasts. More are expected to be found because only a fraction of the vast site, a gravel quarry, has been excavated.

Judging by the quality of the finds, the site is a goldmine. They range from other ice-age giants, such as elks – twice the size of their descendants today, with antlers 10ft across – to tiny creatures, notably dung beetles, which co-evolved with megafauna, using their droppings for food and shelter, and freshwater snails, just like those found today. Even seeds, pollen and plant fossils, including extinct varieties, have been preserved at this site.

Neanderthals Changed Ecosystems 125,000 Years Ago – Were Not “Primal Hippies


Hunter-gatherers caused ecosystems to change 125,000 years ago. These are the findings of an interdisciplinary study by archaeologists from Leiden University in collaboration with other researchers. Neanderthals used fire to keep the landscape open and thus had a big impact on their local environment. The study was published in the journal Science Advances on December 15, 2021.

“Archaeologists have long been asking questions about the character and temporal depth of human intervention in our planet’s ecosystems. We are increasingly seeing very early, generally weak signs of this,” says Wil Roebroeks, Archaeology professor at Leiden University.

A new 3D model of Skara Brae is offering online visitors an immersive digital experience of the 5,000-year-old Neolithic settlement.

The Historic Environment Scotland (HES) model was created using ultra-fast, high-resolution laser scanners which capture 3D spatial data in the form of a point cloud. Hundreds of overlapping photographs are then combined with the 3D data to create the photogrammetric model.

As well as offering a unique perspective on the iconic site, the digital model also allows users to explore how climate change and its impacts have shaped Skara Brae – from its discovery just over 170 years ago as the result of a severe winter storm, to the threat of coastal erosion from rising sea levels and increasingly frequent extreme weather events the site is experiencing today.

The British Museum’s major Stonehenge exhibition sees over 430 objects brought together from across Europe to explore the history – and mystery – of the ancient monument

Even the British Museum can’t quite manage to bring the actual stones into the gallery for its forthcoming exhibition exploring the history of our greatest ancient monument.

But as reported widely, they are doing the next best thing by bringing together a highly impressive array of Bronze Age treasures – and the remains of the astonishing wooden monument dubbed Seahenge, which recently emerged after millennia from beneath the sands of a Norfolk beach.

Early Humans May Have Transformed Their Surroundings

(Leiden University)

LEIDEN, THE NETHERLANDS—UPI reports that hundreds of butchered animal bones, some 20,000 stone artifacts, and evidence of fire building have been discovered at a 125,000-year-old Neanderthal site in the Neumark-Nord lake basin in central Germany’s Geisel Valley by a team of researchers led by Wil Roebroeks of Leiden University. Samples of ancient pollen at the site indicate that the area had been cleared of trees, while pollen counts in the nearby Harz Mountains show that they were forested. Neanderthals and other early humans, Roebroeks concluded, were a factor in shaping the vegetation in this environment. “We might expect to find other examples of this, especially since Neanderthals and their contemporaries were skilled in fire technology,” he said.

Hunter-gatherers were making changes to the ecosystem as early as 125,000 years ago, according to a newly published study by researchers from Leiden University in the Netherlands and Johannes Gutenberg University in Germany. Decades of excavations at a quarry known as Neumark-Nord near Halle, Germany, have turned up plentiful evidence of Neanderthal activity, including indications that these hominins may have converted areas of forest into grasslands. This is the earliest evidence of such activity, said the findings, which were published in the journal Science Advances.

“Among other things, we found the remains of hundreds of slaughtered animals, surrounded by numerous stone tools and a huge amount of charcoal remains,” said Wil Reobroeks of Leiden University.

A spectacular 3D video reconstruction of ancient Athens in the late 5th century BC takes the viewer over the city pinpointing its monuments, markets, temples, and neighborhoods.

The video made by Ancient Athens 3D and released in November presents the city the way it would look in the years before the defeat in the Peloponnesian War in 404 BC.

The city of Athens was completely destroyed by the Persian army in the years 480-479 BC. In the years that followed, the Athenians managed to rebuild their city and by the middle of the 5th century BC, the statesman and general Pericles ordered an extensive construction program that made Athens the center of classical Greece.

At least 2 hominin species lived at Laetoli site 3.6 million years ago

A human relative left these five tracks in a 3.6 million-year-old layer of sediment at the Laetoli Fossil site in Tanzania.

The first evidence of human relatives walking on two feet comes from about 70 footprints left by at least two Australopithecus afarensis walking across soft volcanic ash about 3.6 million years ago. A. afarensis was a short hominin with a jutting lower jaw, which walked upright but may also have spent some time in the trees; the most famous member of the species is the fossils of a woman now called Lucy.

Not far from that site, another set of footprints reveals that Lucy and her kin may have lived alongside another bipedal hominin species, one that moved very differently.

The forgotten footprints

When the footprints were first spotted in 1976, the paleoanthropologists who unearthed them from what's called Site A weren't sure what to make of them. Paleoanthropologist Mary Leakey suggested they could be hominin tracks, but others weren't so sure. One anthropologist even suggested the tracks could have been left by a young bear walking on its hind legs for a few steps.

12 Types Of Extinct Human Species And How They Differ


Today, Homo sapiens are the only type of humans on Earth. However, we modern humans are just the most recent of many other human species that once existed. In fact, we don't know how many species, since scientist keep on finding new species of human. As Britannica explains, the forerunners to humans diverged from apes during the Middle Miocene Epoch from 16 to 11.6 million years ago. These nearly-human species then evolved so that by the Pliocene Epoch some 5.3 to 2.6 million years ago, the human genus, Homo, arose.

Species of human are considered distinct by several traits. They are bipedal striders. They generally have large brains. Some also developed tools and use language. These traits became more pronounced as humans evolved further.

What is truly mind blowing is that there were times when there were several different species of human cohabitating the planet. When considering how well we humans of the same species get along with each other, it is not hard to speculate on how intra-human species relations were.

Let's take a look at some of these species of extinct humans and how they differed with one another. The truth of the matter is that the human species was once very diverse.

Ole Ginnerup Schytz had never used a metal detector before. He first gave it a shot on a former classmate's land in Vindelev, Denmark, in December.

Within hours of turning his detector on, Schytz stumbled across one of the largest treasure hoards ever found in the country.

"Well, that's the epitome of improbable luck," the rookie detectorist said in an interview with Danish outlet TV Syd earlier this month. "Denmark is 43,000 square kilometers, and then I happen to choose to put the detector exactly where this find was."

Whence the White Horse of Uffington?

 


The White Horse of Uffington, a spectacular chalk figure on an English hillside, challenges the very idea of “heritage” as an unbroken line of descent. Made sometime between 1380 and 550 BCE by people who cut meter-deep trenches and filled them with chalk, the horse pattern should have disappeared under encroaching vegetation long ago. But it has been the work of generations to “scour” it—weeding, cleaning, and adding more chalk. It’s this tradition of scouring which so intrigues scholar Philip Schwyzer.

“Like other monuments of similar antiquity, the Horse has been the site of shifting and contested meanings,” writes Schwyzer. “Yet the White Horse is unique among such artifacts in that it has never been neglected, but has always possessed a real and active significance for the inhabitants of the immediate vicinity.”

Europe was considerably colder 44,000 years ago than previously thought, according to new research. The finding is forcing a rethink about early human migration patterns and where our ancestors preferred to settle.

“The expansion of Homo sapiens across Eurasia marked a major milestone in human evolution that would eventually lead to our species being found across every continent,” write the authors of new research published today in Science Advances.

But scientists still aren’t sure how early modern humans managed to pull off this remarkable migrational trick, given considerable environmental variations around the world. The new study, co-authored by Sarah Pederzani from the Max-Planck-Institute for Evolutionary Anthropology, sought to explore the climatic conditions experienced by Homo sapiens when venturing from southwest Asia to Europe.

Study says pigments on cave stalagmites were applied through ‘splattering and blowing’ more than 60,000 years ago

Neanderthals, long perceived to have been unsophisticated and brutish, really did paint stalagmites in a Spanish cave more than 60,000 years ago, according to a study published on Monday.

The issue had roiled the world of paleoarchaeology ever since the publication of a 2018 paper attributing red ocher pigment found on the stalagmitic dome of Cueva de Ardales to our extinct “cousin” species.

The dating suggested the art was at least 64,800 years old, made at a time when modern humans did not inhabit the continent.

But the finding was contentious, and “a scientific article said that perhaps these pigments were a natural thing”, a result of iron oxide flow, Francesco d’Errico, co-author of a new paper in the journal PNAS, told AFP.

Long-Lost Fragment of Stonehenge Gives Unprecedented Glimpse Inside Ancient Monument

"We have CT-scanned the rock, zapped it with X-rays, looked at it under various microscopes and analyzed its sedimentology and chemistry," said study lead author David Nash, a professor of physical geography at the University of Brighton in England.

"With the exception of thin-section analyses and a couple of the chemical methods, all of the techniques we used in the study were new both to Stonehenge and the study of sarsen stones in the UK," Nash told Live Science in an email.

Stonehenge's central circle of pillars was erected during the Neolithic period, about 2,500 years ago, according to English Heritage, a nonprofit organization that manages historic monuments in England. 

"Sarsens were erected in two concentric arrangements – an inner horseshoe and an outer circle – and the bluestones [smaller monument stones] were set up between them in a double arc," English Heritage said on its website.

New findings unveil a missing piece of human prehistory

IMAGE: GEOGRAPHICAL AND TEMPORAL DISTRIBUTION OF NEWLY SAMPLED INDIVIDUALS

A joint research team led by Prof. FU Qiaomei from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences sequenced the ancient genomes of 31 individuals from southern East Asia, thus unveiling a missing piece of human prehistory.

The study was published in Cell on June 24.

Prof. FU's team used DNA capture techniques to retrieve ancient DNA from Guangxi and Fujian, two provincial-level regions in southern China. They sequenced genome-wide DNA from 31 individuals dating back 11,747 to 194 years ago. Of these, two date back to more than 10,000 years ago, making them the oldest genomes sampled from southern East Asia and Southeast Asia to date.

Why could Stonehenge be stripped of world heritage site status?

Unesco has confirmed that Stonehenge could be stripped of its world heritage site status, over its concern that a road tunnel, backed by the government, would irreversibly damage an area of “outstanding universal value”.

A report to Unesco’s world heritage committee setting out concerns about the £1.7bn A303 road tunnel was approved unchanged on Thursday. Unless the designs for the two-mile (3.3km) tunnel are extended and changed, the committee recommends placing Stonehenge on Unesco’s list of world heritage in danger next year.

Last month the high court was told that a decision by Grant Shapps, the transport secretary, to approve the tunnel last November was unlawful because it did not properly consider damage that would be done to a string of prehistoric sites and many thousands of ancient artefacts.

Unesco’s committee found that if the high court confirms planning consent for the tunnel, Stonehenge should be placed on its danger list. It said that despite minor improvements to the original plan, the proposed cut-and-cover tunnel would irreversibly damage an area of “outstanding universal value”.

The final meal of the famous 'bog man' revealed: Tollund Man feasted on porridge and fish before being killed as a ritual sacrifice 2,400 years ago, study reveals

The amazingly well-preserved head of the Tollund Man - a man who lived during the
4th century BC

Tollund Man's gut contents had been analysed forensically when he was discovered in 1950, uncovering traces of cereals and wild plants. 

When Tollund Man was autopsied in 1950, his intestines were still preserved, and the alimentary canal from the stomach to anus was removed in one piece with its contents still in place.  

Now, experts from Silkeborg Museum in Denmark, say they have been able to reconstruct the last meal of Tollund Man in greater detail than ever before – right down to how it was prepared. 

The researchers used a few millilitres of material from the large intestine for analyses to give the 'most detailed study' yet on the gut contents of a bog body.

Broxmouth Hillfort: Study reveals clues ancient people kept loved-ones mundane keepsakes

One of the graves at the site Pic: Broxmouth Project Archive

 They were a people who lived almost two thousand years ago, who would have been on nodding terms with the legions of Roman Britian and who may have decorated their homes with the severed limbs and heads of their enemies. 

Yet despite the gulf of time and taste in interior decoration which separates the ancient inhabitants of Scotland and its modern population today, it appears that holding onto mementos of loved ones was just as important then as it is now.  

A fresh analysis of artefacts uncovered at the Broxmouth hillfort site, near Edinburgh, has raised the tantalising prospect that everyday items were kept by iron Age people as an emotional reminder of those no longer there, and a ‘continuing bond’ with the deceased.

Scientists found fossils from a new species of human that’s 130,000 years old


Scientists from Israel stumbled upon an unexpected discovery while studying fossilized pieces of bone dug up near a cement plant. The fragments from a skull and lower jaw with teeth belonged to a person who lived in the area some 130,000 years ago, but the human is unlike anything we’ve known so far.

The researchers gave it a new name since we’re looking at a different species of human that has never been seen before. They’re calling it Nesher Ramla Homo, after a location southeast of Tel Aviv where it was discovered. This human had particular characteristics unseen in other skeletal findings from the same period. The researchers found that Nesher Ramla Homo had a flat skull, very large teeth, and a jaw bone with no chin. The species may have lived alongside Homo sapiens for more than 100,000 years, and they’re believed to be the precursor to the Neanderthal, the skull of which is seen above. The discovery might upend everything we knew about human evolution on Earth.

“The discovery of a new type of Homo is of great scientific importance,” Tel Aviv University’s Israel Hershkovitz said in a statement. “It enables us to make new sense of previously found human fossils, add another piece to the puzzle of human evolution, and understand the migrations of humans in the old world.”

The Nesher Ramla might have had unusual skull anatomy, but the study says they resembled pre-Neanderthal groups in Europe.

“This is what makes us suggest that this Nesher Ramla group is actually a large group that started very early in time and are the source of the European Neanderthal,” Tel Aviv University physical anthropologist Hila May said in a statement. She added that science has never been able to explain how Homo sapien genes were present in the earlier Neanderthal population in Europe. The Nesher Ramla may be the missing link, as the species may have interbred with Homo sapiens.

Massive human head in Chinese well forces scientists to rethink evolution

The discovery of a huge fossilised skull that was wrapped up and hidden in a Chinese well nearly 90 years ago has forced scientists to rewrite the story of human evolution.

Analysis of the remains has revealed a new branch of the human family tree that points to a previously unknown sister group more closely related to modern humans than the Neanderthals.

The extraordinary fossil has been named a new human species, Homo longi or “Dragon man”, by Chinese researchers, although other experts are more cautious about the designation.

“I think this is one of the most important finds of the past 50 years,” said Prof Chris Stringer, research leader at the Natural History Museum in London, who worked on the project. “It’s a wonderfully preserved fossil.”

The skull appears to have a remarkable backstory. According to the researchers, it was originally found in 1933 by Chinese labourers building a bridge over the Songhua River in Harbin, in China’s northernmost province, Heilongjiang, during the Japanese occupation. To keep the skull from falling into Japanese hands it was wrapped and hidden in an abandoned well, resurfacing only in 2018 after the man who hid it told his grandson about it shortly before he died.
