Archaeology/Paleontology news
« on: November 26, 2018, 07:21:47 AM »
This thread may be used to inform forumites of interesting archeology/paleontology news, lets keep the posts short and always link to a source, please.
I'm opening the thread with a local find. The site is under 10 km from my place.
Part of the burial ground of the earliest christian church yet found in Finland has been found, and the burial of a 13th century women has been excavated. No written records of this site exist. Among finds are remnants of cloth used during the time, as of yet the colors used are unknown, samples of the cloths are sent to Belgian laboratory for color analysis. Parts of socks and a skirt (apparently also a cape) have been identified.

Meanwhile in Denmark...

Oldest ever traces of the plague found in Falköping

In a 5,000 year old grave outside Falköping, scientists have found the oldest traces of the plague bacterium's DNA in the world.

"The discovery of such an early variant of the bacterium in Falköping was totally unexpected since previous findings pointed to Yersinia pestis as having originated in Asia.

The find in Falköping also means that the researchers may have solved another mystery. It was only recently discovered that people in different regions of Eurasia were all infected with the plague during the Bronze Age.

t was by analysing 'molecular clock' data that the researchers discovered that different strains of the plague bacterium spread very rapidly in Eurasia between 5,000 and 6,000 years ago. This matches exactly a period in South-East Europe when the first large population densities arose but also collapsed. It was also at this time that many technological breakthroughs occurred such as the wheel, the use of draught animals, and metallurgy – breakthroughs that facilitated long-distance trade, for example.

Not archaeology per se if if this pans out it will be useful for the field so i am smuggling it in here:

Chinese cave holds carbon dating ‘Holy Grail’

Stalagmites in a Chinese cave have given scientists all they need to reconstruct the historical record of atmospheric radiocarbon (carbon-14) back to the carbon dating limit of around 54,000 years ago.

...

 carbon dating requires calibrating because levels of carbon-14 in the atmosphere vary from year to year. Tree ring data provides a good gauge for carbon dating because their growth reflects their yearly uptake of atmospheric carbon-14. But tree ring data only goes back around 13,000 years.

...
Hai Cheng at Xi’an Jiaotong University, China, and colleagues in the US previously discovered that a stalagmite in Hulu Cave in China showed unusually low and stable amounts of dead carbon that allowed for accurate carbon-14 calibration between around 27,000 and 10,500 years ago. Now the team have studied two older stalagmites in the cave to help take carbon dating to its limit.

Neanderthals Were Intelligent Enough To Make Spears That Could Kill Animals At A Distance

...

The 300,000-year-old Schöningen spears are throwing spears from the Palaeolithic Age that hold the record as the oldest known wooden artifacts in the world. They are also the oldest completely preserved hunting weapons from prehistoric Europe so far discovered.

...

To find out if the Schöningen spears could hit a target at a distance, Annemieke Milks, from University College London, and colleagues made replicas of the prehistoric weapons. They also asked six javelin athletes to throw the spears.

The researchers chose javelin athletes for the study because they have the skill to throw at high velocity, which can match of the capability of Neanderthal hunters.

Hunting Prey At A Distance
The athletes showed they could hit a target at a range of up to 20 meters, and with significant impact that could translate into killing a prey.

This means the wooden spears would have allowed the Neanderthals to use them as hunting weapons and kill at a distance.

The Neanderthals have long been known as hunters but the finding is significant since earlier studies suggest these archaic human species could only hunt and kill their prey at a close range. The demonstrated range was, in fact, double the distance scientists previously thought the spears could be thrown.

and more on:
https://www.techtimes.com/articles/237995/20190126/neanderthals-were-intelligent-enough-to-make-spears-that-could-kill-animals-at-a-distance.htm

One of my pet peeves is scientists painting Neanderthals as primitive brutes (which they did to make modern us more special). Of course nowadays we know they and Homo Sapiens mixed so they could probably communicate.

Agreed, with the additional observation that Neanderthals were Homo Sapiens...Also as we learn how many non-homo animals use tools, even as weapons, this news makes even more sense.

A model of the evolution of the genus Homo over the last 2 million years (vertical axis). The rapid "Out of Africa" expansion of H. sapiens is indicated at the top of the diagram, with admixture indicated with Neanderthals, Denisovans, and unspecified archaic African hominins. Late survival of robust australopithecines (Paranthropus) alongside Homo until 1.2 Mya is indicated in purple.

Homo sapiens (anatomically modern humans) emerges close to 300,000 to 200,000 years ago,[6] most likely in Africa, and Homo neanderthalensis emerges at around the same time in Europe and Western Asia.

Neanderthals and Denisovans Shared a Siberian Cave for Thousands of Years, New Research Suggests


Results from this work showed that Denisovans first occupied the cave around 287,000 years ago, and continued to live in the cave until around 55,000 years ago. Neanderthals arrived at the cave around 193,000 years ago, and they continued to live there up until around 97,000 years ago—an overlap of 96,000 years. The bones of 27 animals, including mammals and fishes, along with 72 species of plants, were also analysed, pointing to a variable climate in the region during the millennia of occupation at the cave. At times, the region was relatively warm, featuring forests of broad-leaved trees, but at other times it was a harsh and desolate tundra-steppe habitat.

A taste for fat may have made us human

Long before human ancestors began hunting large mammals for meat, a fatty diet provided them with the nutrition to develop bigger brains, posits a new paper in Current Anthropology.

The paper argues that our early ancestors acquired a taste for fat by eating marrow scavenged from the skeletal remains of large animals that had been killed and eaten by other predators. The argument challenges the widely held view among anthropologists that eating meat was the critical factor in setting the stage for the evolution of humans.

...

"The reservoirs of fat in the long bones of carcasses were a huge calorie package on a calorie-poor landscape. That could have been what gave an ancestral population the advantage it needed to set off the chain of human evolution."

...

A meat-centered paradigm for human evolution hypothesizes that an ape population began more actively hunting and eating small game, which became an evolutionary stepping stone to the human behavior of hunting large animals.

The paper argues that this theory does not make nutritional sense. "The meat of wild animals is lean," Thompson says. "It actually takes more work to metabolize lean protein than you get back."

In fact, eating lean meat without a good source of fat can lead to protein poisoning and acute malnutrition. Early Arctic explorers, who attempted to survive on rabbit meat exclusively, described the condition as "rabbit starvation."

Modern 21st Century Anglo-Saxon man mostly just eats the lean meat of an animal. Three or four generations or more ago this was not the case for most people. Everything got eaten - the offal, the tripes, the head, and the marrow. I remember being at a smallholder credit meeting in Malawi back in the early 1980's. The one bit of the goat we had for dinner I could not eat was intestines on a stick. I was not keen on bat kebabs either. Chinese cuisine - in China - also uses all of the animal.

To say that an early humanoid would just have eaten the lean meat from an animal it killed is just stupid, as were those early Arctic explorers (and like Scott who would not eat the horses to supplement their food supply on his fatal Antarctic adventure).

And just about all predators will eat carrion if it is available and digestible. So an argument that says carrion vs an argument that says hunting is also completely dumb, as they are not mutually exclusive.

"Are you joking" Iirc it's what the book said, the consensus now seems to be that the flow ceases due to external water pressure[?] whereas the book associated it with other reflex actions, the heart slowing when the head goes under water being one, rapid reduction of flow to near surface capillaries another.

"The Naked Ape" by Desmond Morris opened my mind to the possibility of an aquatic ancestor. Living in a commune at Ortega Hot Springs convinced me that those ancestors were on to something good. :)

The Black Death May Have Transformed Medieval Societies In Sub-Saharan Africa

In the 14th century, the Black Death swept across Europe, Asia, and North Africa, killing up to 50% of the population in some cities. But archaeologists and historians have assumed that the plague bacterium Yersinia pestis, carried by fleas infesting rodents, didn’t make it across the Sahara Desert.

...

Plague is endemic in parts of Africa now; most historians have assumed it arrived in the 19th century from India or China. But Gérard Chouin, an archaeologist and historian at the College of William & Mary in Williamsburg, Virginia, and a team leader in the French National Research Agency’s GLOBAFRICA research program, first started to wonder whether plague had a longer history in sub-Saharan Africa while excavating the site of Akrokrowa in Ghana. Founded around 700 C.E., Akrokrowa was a farming community surrounded by an elliptical ditch and high earthen banks, one of dozens of similar “earthwork” settlements in southern Ghana at the time. But sometime in the late 1300s, Akrokrowa and all the other earthwork settlements were abandoned. “There was a deep, structural change in settlement patterns,” Chouin says, just as the Black Death ravaged Eurasia and North Africa. With GLOBAFRICA funding, he has since documented a similar 14th century abandonment of Ife, Nigeria, the homeland of the Yoruba people, although that site was later reoccupied.

Cave of relics found under Mayan ruins of Chichen Itza

Archaeologists have discovered a cave filled with hundreds of artifacts beneath the ruins of the Mayan city of Chichen Itza in Mexico, the lead researcher on the project said Monday, calling the find "incredible."

...

It sits about 24 meters (80 feet) underground, and contains multiple chambers connected by narrow passages -- often so narrow that researchers had to crawl or drag themselves through them, De Anda said.

His team has explored about 460 meters of the cave so far, and does not know how far it stretches, he added.

The relics found include seven incense burners shaped like the Mayan rain god Chaac, which researchers believe were offerings meant to bring rain.

...

De Anda's team plans to continue exploring the cave. Rather than remove the artifacts they find, they will study them on site, he said.

‘Elixir of Immortality’ Uncovered in 2,000-Year-Old Chinese Tomb 
https://gizmodo.com/elixir-of-immortality-uncovered-in-2-000-year-old-chi-1833038438



A yellowish liquid found in a bronze pot dating back some 2,000 years is not wine, as Chinese archaeologists initially thought. It’s actually an “elixir of immortality” concocted during ancient times.

The bronze pot was discovered last October by archaeologists working at the tomb of a noble family in the Henan Province of central China. The 210-square-meter site in the city of Luoyang dates back to the Western Han Dynasty (202 BCE to 8 CE) and, in addition to the pot, yielded the well-preserved remains of a nobleman, painted clay pots, materials made from jade and bronze, and a lamp in the shape of a wild goose.

Intriguingly, the pot contained 3.5 liters (0.9 gallons) of a yellowish liquid exhibiting a very strong alcohol-like smell. At the time, archaeologists figured it was wine—a conclusion consistent with other discoveries dating back to the same period. Back then, wine made from rice and sorghum grains were used in ritual sacrifices and ceremonies, reported Xinhua.

But as Xinhua points out in an update to this discovery, further lab work has shown that the substance isn’t wine at all. The liquid is primarily comprised of potassium nitrate and alunite—the main ingredients of a life-enriching elixir documented in ancient Taoist texts.

Geologic Evidence Supports Theory that Major Cosmic Impact Event Occurred Approximately 12,800 Years Ago   
https://phys.org/news/2019-03-geologic-evidence-theory-major-cosmic.html



... in a paper published in the journal Nature Scientific Reports, Kennett and colleagues, led by Chilean paleontologist Mario Pino, present further evidence of a cosmic impact, this time far south of the equator, that likely lead to biomass burning, climate change and megafaunal extinctions nearly 13,000 years ago.

"We have identified the Younger Dryas Boundary (YDB) Impact Hypothesis layer at high latitudes in the Southern Hemisphere at near 41 degrees south, close to the tip of South America," Kennett said. This is a major expansion of the extent of the Younger Dryas Boundary (YDB) Impact Hypothesis event." The vast majority of evidence to date, he added, has been found in the Northern Hemisphere.

Investigators recognized changes known to be associated with YDB impact event. They included a "black mat" layer, 12,800 years in age, that coincided with the disappearance of South American Pleistocene megafauna fossils, an abrupt shift in regional vegetation and a disappearance of human artifacts.

... the group decided to run analyses of impact-related proxies in search of the YDB layer," Kennett said. This yielded the presence of microscopic spherules interpreted to have been formed by melting due to the extremely high temperatures associated with impact. The layer containing these spherules also show peak concentrations of platinum and gold, and native iron particles rarely found in nature.

"Among the most important spherules are those that are chromium-rich," Kennett explained. The Pilauco site spherules contain an unusual level of chromium, an element not found in Northern Hemisphere YDB impact spherules, but in South America. "It turns out that volcanic rocks in the southern Andes can be rich in chromium, and these rocks provided a local source for this chromium," he added. "Thus, the cometary objects must have hit South America as well."



"The plant assemblages indicate that there was an abrupt and major shift in the vegetation from wet, cold conditions at Pilauco to warm, dry conditions," Kennett said. According to him, the atmospheric zonal climatic belts shifted "like a seesaw," with a synergistic mechanism, bringing warming to the Southern Hemisphere even as the Northern Hemisphere experienced cooling and expanding sea ice.

The rapidity—within a few years—with which the climate shifted is best attributed to impact-related shifts in atmospheric systems, rather than to the slower oceanic processes, Kennett said.

Nile shipwreck discovery proves Herodotus right – after 2,469 years

In the fifth century BC, the Greek historian Herodotus visited Egypt and wrote of unusual river boats on the Nile. Twenty-three lines of his Historia, the ancient world’s first great narrative history, are devoted to the intricate description of the construction of a “baris”.

For centuries, scholars have argued over his account because there was no archaeological evidence that such ships ever existed. Now there is. A “fabulously preserved” wreck in the waters around the sunken port city of Thonis-Heracleion has revealed just how accurate the historian was.

Huge fossil discovery made in China's Hubei province

...

Scientists say they have discovered a "stunning" trove of thousands of fossils on a river bank in China.

The fossils are estimated to be about 518 million years old, and are particularly unusual because the soft body tissue of many creatures, including their skin, eyes, and internal organs, have been "exquisitely" well preserved.

Palaeontologists have called the findings "mind-blowing" - especially because more than half the fossils are previously undiscovered species.

The fossils, known as the Qingjiang biota, were collected near Danshui river in Hubei province.

More than 20,000 specimens were collected, and a total of 4,351 have been analysed so far, including worms, jellyfish, sea anemones and algae.

New Analysis Confirms Oldest Mariner's Astrolabe Ever Found
https://gizmodo.com/new-analysis-confirms-oldest-mariners-astrolabe-ever-fo-1833497494

Scientists have confirmed that a gunmetal disk uncovered off the coast of Oman is the oldest known mariner’s astrolabe, according to a new study.

The disk was found underwater at the Sodré shipwreck site, and contained iconic Portuguese imagery still found on the flag of Portugal. Though it appeared to be an astrolabe, it required further confirmation. Laser imagery from scientists at the University of Warwick in the United Kingdom has now revealed scale markers along the disk’s edges, confirming that it was in fact an early navigational tool. Astrolabes were instruments used by mariners beginning in the late 15th century to determine latitude, which they did by pointing the disk at the Sun and reading the markings on its sides.

The Sodré astrolabe is believed to have been made between 1496 and 1501 and is unique in comparison to all other mariner's astrolabes.

The astrolabe comes from a set of excavations of the Sodré shipwreck off of Al Hallaniyah, an island off of the Omani coast. The ships were part of a subfleet of the Portuguese armada on a trip to India led by Vasco da Gama in 1502-1503, commanded by da Gama’s uncles Vicente and Brás Sodré. They’d anchored by Al Hallaniyah to find shelter from the seasonal monsoon winds—but a particularly strong wind sunk the ship, killing many of its sailors and Vicente Sodré.

Archeologists believe Norway Find is Rare Viking Ship Burial
https://phys.org/news/2019-03-archeologists-norway-rare-viking-ship.html

Archeologists believe they have found a rare Viking ship burial site in a region of Norway known for its Viking-era treasures, Norwegian officials said Monday.

Using ground-penetrating radar (GPR), experts found a ship-shaped anomaly near other Viking burial mounds in the Borre Park in Vestfold county, southeast of Oslo.

"The GPR data clearly show the shape of a ship, and we can see weak traces of a circular depression around the vessel. This could point to the existence of a mound that was later removed," Terje Gansum, leader of the department for cultural heritage management in Vestfold county, said in a statement.

There are only seven ship burials dating from the Viking Age (800-1050) in Europe, including three located in Vestfold county.

Another Viking ship burial was believed to have been found in Jellestad in southeastern Norway last year.

Stunning Fossils Discovery Details the Day Dinosaurs Were Wiped Out 
https://phys.org/news/2019-03-million-year-old-deathbed-linked-dinosaur-killing-meteor.html



Buried for 66 million years, a prehistoric graveyard is revealing what happened in the minutes after a giant asteroid slammed into the Earth and wiped out the dinosaurs, a new study says.

The site, part of the Hell Creek Formation in what is now North Dakota, used to lie along an inland sea that divided North America into two land masses.

“Essentially, what we've got there is the geologic equivalent of high-speed film of the very first moments after the impact,” paleontologist Robert DePalma, the study's lead author, told National Geographic.

Perfectly preserved fossils of fish, animals and plants at the site, which is nicknamed Tanis, offer a detailed recording of what happened immediately after the killer asteroid struck off Mexico's Yucatan Peninsula, according to the study to be published Monday in the Proceedings of the National Academy of Sciences.

Some of the fossilized fish at the site inhaled tiny glass beads (tekites) formed by the impact.

... “This is the first mass death assemblage of large organisms anyone has found associated with the K-T boundary,” DePalma said. “At no other K-T boundary section on Earth can you find such a collection consisting of a large number of species representing different ages of organisms and different stages of life, all of which died at the same time, on the same day.” 

... We are looking at the moment-by-moment records of one of the most notable impact events in Earth’s history. No other site has a record quite like that. And this particular event is tied directly to all of us — to every mammal on Earth, in fact. Because this is essentially where we inherited the planet. Nothing was the same after that impact. It became a planet of mammals rather than a planet of dinosaurs."

For another take on the recent K-T (now K-Pg) Boundary news:  A bad day at the end of the Cretaceous by Steve Drury, concerning both DePalma, R.A. and 11 others 2019, A seismically induced onshore surge deposit at the KPg boundary, North Dakota, Proceedings of the National Academy of Science; and Preston, D. 2019, The day the dinosaurs died, The New Yorker.

Some snippets:

 its contents are the stuff of dreams for any aspiring graduate student of palaeontology; the Indiana Jones opportunity.

The paper itself contains little of the information that dominated Preston’s New Yorker article and the global media coverage.
...
If verified in later peer-reviewed publications, DePalma et al’s work would help resolve the gradual vs sudden hypotheses for the end-Cretaceous mass extinction.

New Species of Ancient Human Discovered in Philippines Cave 
https://www.theguardian.com/science/2019/apr/10/new-species-of-ancient-human-homo-luzonensis-discovered-in-philippines-cave

A new species of ancient human, thought to have been under 4ft tall and adapted to climbing trees, has been discovered in the Philippines, providing a twist in the story of human evolution.

The specimen, named Homo luzonensis, was excavated from Callao cave on Luzon island in the northern Philippines and has been dated to 50,000-67,000 years ago – when our own ancestors and the Neanderthals were spreading across Europe and into Asia.

Quote
... “We now know that it was a much more complex evolutionary history, with several distinct species contemporaneous with Homo sapiens, interbreeding events, extinctions,” said Détroit. “Homo luzonensis is one of those species and we will [increasingly see] that a few thousand years back in time, Homo sapiens was definitely not alone on Earth.”

... Most intriguing was the presence of a curved toe bone, which closely resembled the anatomy of far more ancient species such as Australopithecus, known only in Africa and dating to 2m-3m years ago. ... Normally this anatomy would indicate a mixed lifestyle with an ability to walk on two legs and climb trees.

Another mystery is how they arrived at Luzon, a large island that has never been connected to the mainland by a land bridge. One possibility is that the early humans set out to sea intentionally on some form of raft; another is that they were washed there in relatively large numbers due to a natural event such as a tsunami.

A lot of species we can see today will be "paleontology" in a hundred years.
