The Spirit Cave Mummy is Over 10,000 Years Old

The Spirit Cave Mummy is Over 10,000 Years Old

The remains were found with moccasins, a rabbit-skin blanket, and many other artifacts.

Mummies are deceased humans or animals that have been preserved, which keeps their remains from decaying any further. While Ancient Egyptians are most commonly associated with the mummification process, there are actually mummies found all over the world.

The process can either be deliberate or accidental.

Although you may have used toilet paper for a mummy costume in the past, the real method includes wrapping the dead body in linen and embalming it. And on rare occasions, environmental conditions happen to be just right to result in a body’s preservation.

Now you may be wondering who the oldest mummy is, and that honour goes to the Spirit Cave Mummy at 10,600 years old. However, its importance runs deeper than just its old age.

The Spirit Cave Mummy was part of a fierce battle between the government and a Native American tribe over its cultural and scientific significance.

The Spirit Cave Mummy was discovered in 1940 by archaeologists and husband-and-wife team George and Sydney Wheeler. They found several sets of remains in a small rocky cave located in northwest Nevada, one of which was partially mummified.

The mummified man was determined to have died while he was in his forties. His remains were found wrapped in a rabbit-skin blanket and reed mats, and he was still wearing moccasins.

At the time the man’s mummy was found, it was estimated that he died between 1,500 and 2,000 years ago. However, when more advanced testing methods came along in the 1990s, it was found that the skeleton was actually 10,600 years old, making the Spirit Cave Mummy the oldest mummy found in North America.

There was a long legal argument starting in 1997 over who should have possession of the oldest mummy in North America. Native Americans from the region believed that they should have the remains due to cultural affiliation since the mummy was found in their ancestral homeland. However, when the federal government rejected their request for possession, the Paiute-Shoshone Tribe of the Fallon Reservation and Colony sued the government.   

The government alleged that they wanted possession of the remains for scientific research, but the US Native American Graves Protection and Repatriation Act states that Native Americans have control over resurfaced items and remains to which they have biological or cultural connections.

The US government’s Bureau of Land Management is the agency that declined the tribe’s request. Although a US District Court Judge told the agency to reconsider their decision, no progress was really made with this case for 20 years.

Initially, the Paiute-Shoshone Tribe did not want to pursue genetic analysis to prove that the mummy was an ancestor, but eventually, they agreed to do so.

A couple of years later, the DNA sequencing test revealed that the skeleton was in fact related to the indigenous people of North and South America. On November 22, 2016, the mummy was repatriated to the Paiute-Shoshone Tribe and they held a reburial for the remains.

Several scientific findings were made due to the discovery of the Spirit Cave Mummy. It was one of the first to be dated using accelerated mass spectrometer radiocarbon dating, a process that revealed the mummy to be much older than previously thought. It raised further questions about migration patterns in early North and South America. Additionally, a total of 67 artefacts were recovered from the cave along with the mummy, revealing how ancient humans lived and died.

Although it took many years for the mummy to be repatriated to the local Native American tribe, DNA testing ended up being a win-win for all parties involved.

The Paiute-Shoshone Tribe was able to prove ancestry and have the remains returned to them, and the government was able to gain some vital scientific information from performing the test before repatriating the remains.

There is so much more to be discovered about the past, and each finding brings scientists closer to more answers. DNA analysis on the Spirit Cave Mummy gave more insight into early humans and resolved the conflict between the federal government and the Fallon Paiute-Shoshone Tribe.

Skeletons in Dutch Mass Grave Are British Soldiers

Skeletons in Dutch Mass Grave Are British Soldiers

More than 80 British soldiers who were buried in a mass grave in the Netherlands 200 years ago died of disease rather than during combat, archaeologists have revealed. The mass grave, which contains 82 skeletons, was found by chance in the town of Vianen in November 2020.

The soldiers buried there are believed to have died during the Flanders Campaign of 1793-1795, in which the British fought the French.

The campaign was part of the First Coalition war, which pitched post-revolutionary France against an alliance made up of Britain, Prussia, Russia, the Netherlands and Austria.

Now, analysis of some of the remains has shown that the soldiers endured extremely tough conditions, both in civilian life and after they joined up.

Instead of dying of sabre wounds, musket bullets or artillery fire, they died of disease.

“Most of them died of illness rather than fighting on the battlefield,” Hans Veenstra, an archaeologist, told The Telegraph.

“The conditions in which they lived were extremely poor. They slept in small tents in all weather, their food was not of good quality and there were all kinds of bacteria that had the chance to spread disease.”

The mass grave was found close to the site of what was a British military field hospital, which was set up in December 1794.

Of the six skeletons which have so far been examined with isotope analysis of their bones, three are believed to be British – two came from Cornwall and another from a town somewhere in central England. Two others are of possible English descent, while the sixth was German.

“That is not particularly strange because German forces were fighting with the British during the Flanders campaign,” said Mr Veenstra, from De Steekproef, a Dutch archaeological research company.

A mass grave found during research for the new canal

The mass grave was found by chance when archaeologists were conducting research in the area prior to plans to excavate a new canal.

“It was a big surprise, it was found purely by accident. The chances of finding so many bodies, centuries later, is very small,” he said.

While the average age of the soldiers was 26, some were teenagers.

They were buried in wooden coffins but without their uniforms. “Those would have been taken by the army and given to other soldiers,” said Mr Veenstra.

Stonehenge: Archaeologists unearth 10,000-year-old hunting pits

Stonehenge: Archaeologists unearth 10,000-year-old hunting pits

Thousands of pits believed to have been used by prehistoric hunters have been unearthed near Stonehenge. The find, by University of Birmingham and Ghent University researchers, included sites over 10,000 years old.

Researchers say the largest pit is the most ancient trace of how land was used at Stonehenge

One of the pits, which was 13ft (4m) wide and 6.5ft (2m) deep, was the largest of its kind in northwest Europe, the archaeologists said.

The discoveries were made using a combination of novel geophysics and “traditional” archaeology, they added.

The researchers said the pits, dating from between around 8,200 BCE and 7800 BCE, showed hunter-gatherers had roamed the landscape during the early Mesolithic period when Britain was re-inhabited after the last Ice Age.

The discovery was partly made with a technique known as electromagnetic induction survey, which uses the electrical conductivity of soil to provide information that can be used to find materials underground.

It was the first extensive electromagnetic induction survey undertaken in the Stonehenge landscape, according to the University of Birmingham.

The hunting pits were discovered by the archaeologists near the site of Stonehenge

Paul Garwood, senior lecturer in prehistory at the University of Birmingham, said what had been discovered was “not a snapshot of one moment in time”.

“The traces we see in our data span millennia, as indicated by the 7,000-year timeframe between the oldest and most recent prehistoric pits we’ve excavated.

“From early hunter-gatherers to later Bronze Age inhabitants of farms and field systems, the archaeology we’re detecting is the result of the complex and ever-changing occupation of the landscape.”

Dr Nick Snashall, the archaeologist for the Stonehenge and Avebury World Heritage Site, said the team had revealed some of the earliest evidence of human activity yet unearthed in the Stonehenge landscape.

“The discovery of the largest known Early Mesolithic pit in northwest Europe shows this was a special place for hunter-gatherer communities thousands of years before the first stones were erected,” Dr Snashall said.

Philippe De Smedt, associate professor at Ghent University, said the combination of new techniques and traditional archaeology had revealed otherwise “elusive” archaeological evidence around Stonehenge.

Major discovery: Iron Age complex found under a house in Turkey village, says study

Major discovery: Iron Age complex found under a house in Turkey village, says study

A bungled looting scheme has led archaeologists to an underground Iron Age complex in Turkey that may have been used by a fertility cult during the first millennium B.C., a new study finds.

Major discovery: Iron Age complex found under a house in Turkey village, says study
The divine procession panel, digitally highlighted in black, is found in the underground complex in Başbük, Turkey.

The ancient complex, which has yet to be fully investigated due to the instability of the structure, has rare rock art drawings on its walls featuring a procession of deities depicted in an Assyrian style.

This art style appears to have been adopted by local groups, indicating how strongly the culture of the Neo-Assyrian Empire — which hailed from Mesopotamia and later expanded into Anatolia — spread to the people it conquered in this region, according to the new study, published online May 11 in the journal Antiquity. 

“The finding bears witness to the exercise of Assyrian hegemony in the region in its early phases,” one of the study’s authors Selim Ferruh Adalı, an associate professor of ancient history at the Social Sciences University of Ankara, told Live Science in an email.

“The wall panel contains a depiction of the divine procession with previously unknown elements, with Aramaic writing to describe some of the deities while combining Neo-Assyrian, Aramaean and Syro-Anatolian divine iconography.”

Authorities learned about the ancient underground complex in 2017 after looters discovered it beneath a house in a Turkish village and decided to target its treasures. However, police foiled the looters, and investigating officials soon found an artificial opening the looters had cut through the floor of the two-story house in the village of Başbük, in southern Turkey.

This discovery prompted the police to notify the Şanlıurfa Archaeological Museum, whose archaeologists determined that the opening, which measured about 7 by 5 feet  (2.2 by 1.5 meters), led to an entrance chamber, carved out of the limestone bedrock, in the underground complex.

The subterranean complex dates to the early Neo-Assyrian period (around the ninth century B.C.) and features an upper and lower gallery, as well as the entrance chamber. The original opening to the entrance chamber has not yet been found.

Museum experts carried out the rescue excavation in August and September of 2018, Adalı said. However, they suspended the rescue excavation after two months because of the instability of the site. The area is now under the legal protection of Turkey’s Ministry of Culture and Tourism.

During the short period of excavation, archaeologists removed sediment that had fallen due to erosion in the underground spaces, which revealed a decorative rock relief carved into a wall panel.

The panel depicts a procession of gods and goddesses from the Aramean pantheon, some with Aramaic inscriptions next to them.

The excavators sent photos of the inscriptions on the panel to Adalı, who found that the panel had great historical significance.

Archaeologists found Aramaic text to the right of the storm god’s head.

The expansion of the Neo-Assyrian Empire into what is now Turkey inspired a cultural revolution, as the Assyrian elite used art from their courtly style to express their power over the local Luwian- and Aramaic-speaking peoples.

The wall panel in Başbük shows how Assyrian art was adapted into the Aramaean style in the provincial towns and villages, the researchers found.

Four of the eight deities depicted on the panel could not be identified, according to the study. The Aramaic inscriptions label three of the gods: the storm, rain and thunder god Hadad; his consort Atargatis, a goddess of fertility and protection; the moon god Sîn; and the sun god Šamaš. The drawing of Atargatis is the earliest known depiction of this goddess, the principal goddess of Syria, in this region, the researchers added.

“The inclusion of Syro-Anatolian religious themes illustrate an adaptation of Neo-Assyrian elements in ways that one did not expect from earlier finds, Adalı said in a statement, “They reflect an earlier phase of Assyrian presence in the region when local elements were more emphasized.”

The deities on the wall panel suggest that it was “the locus for a regional fertility cult of Syro-Anatolian and Aramaean deities with rituals overseen by early Neo-Assyrian authorities,” Adalı told Live Science. One of those authorities might have been Mukīn-abūa, a Neo-Assyrian official who lived during the reign of the Assyrian king Adad-nirari III (811 B.C. to 783 B.C.). The researchers identified an inscription that might refer to Mukīn-abūa. It’s possible that Mukīn-abūa took control of the region, and that he used this complex to integrate with and win over locals, the researchers said.

Meanwhile, the presence of Neo-Assyrian art in this complex doesn’t necessarily mean that the empire’s artists created this panel. Rather, it’s likely that “the panel was made by local artists serving Assyrian authorities who adapted Neo-Assyrian art in a provincial context,” Adalı said. 

He added that the team suspects further excavations will uncover more areas of the underground complex and possibly yield more examples of artwork, as only a small part of the whole site has been explored so far. A full-scale excavation is expected to take place when the entirety of the site has been prepared, according to the procedures of Turkish cultural heritage laws. 

India knew to use iron 4,000 years ago, archaeological findings show

India knew to use iron 4,000 years ago, archaeological findings show

Carbon dating of cultural deposits found during archaeological excavations in Mayiladumparai in Krishnagiri district has found they belong to 2172 BCE, establishing that the Tamils were aware of the use of iron 4,200 years ago.

Tamil Nadu Chief Minister M K Stalin told the Assembly that the first phase of excavation in 2020-2021 has yielded two important dates – 1615 BCE and 2172 BCE, which provide a new understanding of the nature of cultural deposits.

The AMS dating by Beta Analytical Lab in Florida, US has established three important features – iron appeared in Tamil Nadu as early as 220 BCE, the late Neolithic phase was identified before 2200 BCE as there is a cultural deposit of 25 cm below the dated level, and black-red-redware was in use the late Neolithic phase itself, in contrast to the wider belief that they were introduced in the Iron Age.

Archaeological excavations in Mayiladumparai have found that the date of iron artefacts unearthed ‘ranges from 2172 BCE to 1615 BCE’.

The recent archaeological excavations in Tamil Nadu have thrown up surprises – carbon dating of artefacts in Keeladi, a Sangam Era site near Madurai, and paddy husks found in a burial urn in Sivakalai in Thoothukudi district established their age to 2,600 and 3,200 years old.

“Through the findings, it has been established that Tamils who lived 4200 years ago were aware of iron. Dense forests were converted into fertile lands only after humankind began realising the use of iron. This finding has answered questions relating to the start of agricultural activity in Tamil Nadu,” Stalin said.

He also announced that the Tamil Nadu State Department of Archaeology (TNSDA) will begin work on a comparative study of graffiti found in Keeladi and the signs of the Indus Valley Civilisation.

AMS dating of the Iron Age has so far been done in many places, including in the Gangetic plains and Karnataka, Stalin said, adding that the period that has thrown up in Mayiladumparai is the earliest so far.

“I have been saying that the goal of this government is to establish through scientific methods that the history of India should be rewritten from the Tamil land. The latest findings reinforce our thoughts,” Stalin added.

The Chief Minister also announced that the TNSDA will continue its efforts to trace the journey of ancient Tamils. As part of the efforts, excavations in Pattanam (Kerala), Thalakadu (Karnataka), Vengi (Andhra Pradesh), and Palur (Odisha) will begin this year, Stalin added.

Dr R Sivananthan, Commissioner, TNSDA, told DH that Mayiladumparai can be termed as the earliest Iron Age site in South India as Brahmagiri in Karnataka was the earliest so far with AMS dates going back to 2040 BCE.

“The date we have got for Mayiladumparai is 2172 BCE. It is just about a century and we need more evidence. The earliest evidence of the Iron Age in Tamil Nadu so far was 1500 BCE and Mayiladumparai pushes it back by another six to seven centuries. Since this is just the 1st phase in Mayiladumparai, we should wait for more cultural deposits,” he told DH.

An archaeological expert put the findings in perspective saying that the AMS dating has brought Tamil Nadu “within the Indian framework” as the cultural deposits in Mayiladumparai are 4,200 years old.

“The earliest Iron Age site in Tamil Nadu so far was 1500 BCE old while all other such sites in the country were beyond 2000 BCE. There were a lot of questions on why there was no scientific evidence on the use of iron despite it being mentioned in literature and having rich iron ore in the Salem region. With this, we now have findings,” the expert said.

The report released by the government also spoke about references in Sangam literature on iron, the use of iron, and the methods of making iron weapons. Literature refers to iron as ‘blacksmiths’ and ‘blacksmiths with strong hands’.

“It can be said that the iron industry was very advanced from the fact that many fine words about the iron industry find a place in Tamil literature. One could realise that the iron technology was in an advanced stage as one could find many fine technical terms in Tamil literature,” he said.

18th-Century Bones of Sick Soldiers Identified in the Netherlands

18th-Century Bones of Sick Soldiers Identified in the Netherlands

Eighty-two skeletons found in a mass grave in the Dutch city of Vianen were mainly British soldiers who died of illness in an 18th Century field hospital, archaeologists say. The remains were found outside the city’s old wall in November 2020 and then researched by forensic anthropologist April Pijpelink.

The skeletons were dug up during excavations in late 2020

All but four were men and many originated in southern England.

“It’s most likely these young men came to fight against the French,” she said.

But they lost their lives because of poor hygiene in a field hospital, she told the BBC. “At first we thought these men died of injuries in battle, but during my research, it became clear that around 85% of them suffered from one or more infections, while basically, all their trauma wounds had healed.”

Samples were taken from six of the skeletons and isotope analysis of their bones concluded that one came from southern England, possibly Cornwall, another from southern Cornwall and a third from an urban English environment. Two more may have been from the Netherlands but of possible English descent while the other was from Germany.

The men would have been treated at a field hospital at Batestein Castle in Vianen. As it was a mass grave and they all died under the same circumstances, a sample of six was sufficient, archaeologist Hans Veenstra told the BBC.

There were two wars there in the 18th Century, but only one involved British soldiers: the Flanders Campaign of 1793-95 against France. German soldiers from Hessen and Hanover worked closely with the British during the campaign.

This was part of the First Coalition war, between post-revolutionary France and several other European powers including Britain, Russia, Prussia, Spain, the Netherlands and Austria.

The bones in the mass grave all came from the same period in the 1790s

From late 1794-to 95, British soldiers have treated a short distance from the mass grave, and the researchers believe that the poor and cramped conditions of army life led to reduced resistance to bacterial infection.

The average age of the adult victims was about 26 although some of those who died were just teenagers. Around 60% showed traces of one or more infections which all had one cause – pneumococcal bacteria.

“If you read history books it’s always about the people in power – mostly about armies and generals, kings and queens but never about the ordinary man who had to do all the dirty work,” said Mr Veenstra, who believed this discovery helped fill in a gap in our knowledge of the time.

“That’s what makes this interesting. They lived in very poor conditions, they all had a poor upbringing with a lot of malnutrition and hard work. They’d already damaged their backs by doing hard labour.”

The skeletons were well preserved because they were found in clay outside Vianen’s historic walls

5000-Year-Old Jewellery Making Factory Discovered In Millennia-Old Harappan City In Haryana’s Rakhigarhi

5000-Year-Old Jewellery Making Factory Discovered In Millennia-Old Harappan City In Haryana’s Rakhigarhi

Rakhigarhi in Haryana is world-famous for some of the most well-known sites Harrapan civilisation, and the Archaeological Survey of India (ASI) has been conducting new excavations for the last 32 years. Now, it seems ASI has made one of its biggest discoveries in the 7,000-year-old planned Harappan city with the excavation of a 5000-year-old factory which used to manufacture jewellery.

The excavation and study at Rakhigarhi have so far revealed that this place once not only housed a planned Harappan city with some of the best engineering marvels of the time but also engaged in trading and business practices.

The archaeologists found evidence of town planning, including streets, pucca walls and multi-storeyed houses. Evidence of modern engineering which is currently being used to build big cities– like straight streets, drains, and dustbins placed at corners of streets for garbage– were also found from the excavation site in Rakhigarhi. 

During the latest round of excavation in Rakhigarhi, which is scheduled to be completed by the end of May, skeletons of two women were found along with jewellery. Along with skeletons, utensils used by the deceased were also found.

Elaborating on the latest discoveries, Sanjay K Manjul, Joint Director General, ASI told news agency ANI that Rakhigarhi archaeological site has seven mounds and pieces of evidence of Harappan culture have been uncovered in all seven of them. “Similar excavations have happened before and this is the third phase,” he said.

Sharing his observations on the engineering marvels of the Harappan civilisation, the archaeologist said well-led planning could be observed here, with streets and walls along with it, house complexes, drainage systems, burnt brick structural support and varieties of pottery components with many paintings showing their improved baking technique.

“Copper and gold objects were also found, along with artefacts, beads, sealed scripts with motifs, and ceilings with Harappan script and elephant depictions. This shows their cultural diversity. Our motive is to develop this site iconically,” he added.

History of Rakhigarhi: In Points

  • Rakhigarhi is the largest archaeological site of the Harappan civilisation which comes under two modern villages Rakhi-Shahpur and Rakhigarhi-Khash. For the first time, this site was excavated in 1998-2001 by the ASI. After that from 2013 to 2016, Deccan College, Pune worked here.
  • Rakhigarhi has been classified as a major metropolitan centre of the Harappan culture. During an investigation conducted in 1969 by Professor Suraj Bhan, it was found that archaeological remains of Rakhigarhi and settlements are of the nature of the Harappan culture.
  • Later, during an investigation conducted by the ASI and Pune Deccan College, it came to the fore that this place has a cluster township spread across 500 hectares. It includes 11 mounds which have been named RGR- 1 TO 11.
  • The excavations carried out by the ASI under the directions of Amarendra Nath during the year 1997-98 to 1999-2000 revealed various occupational phases beginning from the pre-formative stage to the mature Harrapan period covering the time from 5th millennia BCE to 3rd millennia BCE based on the radiocarbon dates obtained from various layers.     

How ASI plans to develop Rakhigarhi In Future

According to a report by news agency IANS, there is a procedure going on for a memorandum of understanding between the ASI and Haryana government under which the ancient things of the Rakhigarhi will be displayed in a museum which is under the Haryana government.

The ASI will soon start excavation in September 2022 and after that will throw open these mounds, so that the tourists can get full information. Very soon Rakhigarhi will witness a beeline of tourists as the officials want that when the tourists see the remains they get the information about the antique and the truth about it.

As per the announcement made by the Central government in the Union Budget 2020-21, Rakhigarhi will be developed as one of the five best iconic places for which excavation started on February 24, 2022.

The government’s aim is to facilitate the tourists who come to Rakhigarhi besides exposing structural remains. Besides, its aim is also to understand the settlement of Harappa in Rakhigarhi and the interrelation of seven mounds.

Ancient Chinese Earthquake Detector Invented 2,000 Years Ago Really Worked!

Ancient Chinese Earthquake Detector Invented 2,000 Years Ago Really Worked!

A seismometer or seismoscope is an instrument that detects and measures the motions of the ground as a result of seismic waves gushing from an earthquake, volcanic eruption or powerful explosion.

Ancient Chinese Earthquake Detector Invented 2,000 Years Ago Really Worked!
A modern replica of Zhang Heng’s famous seismoscope.

Today, there are thousands of such instruments dispersed in key places around the world that constantly keep watching, gather data and help seismologists better their understanding of how earthquakes work. And no, we can’t predict earthquakes yet.

You might be surprised to find, however, that the first seismometer was invented in China in 132 AD by a Chinese astronomer, mathematician, engineer, and inventor called Zhang Heng.

The instrument was said to resemble a wine jar six feet in diameter, with eight dragons positioned face down along the outside of the barrel, marking the primary compass directions. In each dragon’s mouth was a small bronze ball.

Beneath the dragons sat eight bronze toads, with their broad mouths gaping to receive the balls.

When the instrument sensed an incoming seismic wave, one of the balls would drop and the sound would alert observers to the earthquake, giving a rough indication of the earthquake’s direction of origin.

The device is said to have been very accurate and could detect earthquakes from afar, and did not rely on shaking or movement in the location where the instrument was positioned.

The first-ever earthquake recorded by this seismograph was supposedly somewhere in the east. Days later, a rider from there reported this earthquake.

Moreover, it had the most wicked ornaments. They don’t make scientific instruments like they used to!

Illustration of world’s first seismoscope.

Of course, the insides of the seismometer were filled with a sensing mechanism of some sort, the contents of which have been lost in time. In all likelihood, a simple or inverted pendulum was employed, according to experts.

In 2005, scientists in Zhengzhou, China built a replica of Zhang’s seismoscope, estimating the content of the inner mechanism by using technology that was available during the great inventor’s time.

They used the replica to detect simulated earthquakes based on waves from four different real-life earthquakes in China and Vietnam.

The seismoscope detected all of them. As a matter of fact, the data gathered from the tests corresponded accurately with that collected by modern-day seismometers!
