5000 Years of History at Zurich Rescue Excavations: Stone Age Wooden Door (and more)

Excavations at the Opera House car park, Zurich, Switserland. Rescue excavations at the construction site of an underground car park in the Swiss city of Zurich are exceeding all expectations.

So far, the remains of at least five successive prehistoricsettlements came to light, as well as some amazing finds.

These including a flint dagger from Italy anda 5000-year-old wooden door – looking incredibly good for its age.

The oldest of the settlements discovered at the Opera House digis dated to as early as 3700 BC.

Underneath these remains, the archaeologists from Zurich’s Structural Engineering Department found sediment layers, which will offer information about the fluctuating water levels of Lake Zurich over time.

In addition to the sediment strata and building features over 8000 wood samples have been recovered.

The absence of oxygen in the lake sediments made that a wealth of organic remains are preserved.

5,000-year-old Stone Age Door

Amongst the remains was a Stone Age door, which is likely to be the third oldest door in Switzerland as well as Europe.

The prehistoric wooden door measures 153 by 88 centimetres and extremely well-preserved, with even its hinges still visible.

Remarkable is the way its planks were held together using a sophisticated plugs system.

Dating of the wood’s tree rings dendrochronology suggests the door was made (or at least, the three felled) in the year 3,063 BC.

More Archaeological Treasures

So far, one human skeleton has been discovered at the Zurich dig.

Other finds at the archaeological site were a heavily used flint dagger from Italy which offers information on the prehistoric transalpine trade routes and a new type of bow and arrow with bark ornament and a yet to be determined adhesive technology.

Stone Age tinderboxes were recovered at the dig, complete with lumps of iron sulphide, fire strikers and mushrooms the F. fomentarius, or Tinder Fungus.

From these boxes, several wooden pieces were found, which will provide further information on the containers’ designs.

The dig also revealed the oldest evidence for the use of wooden shingles in Zurich , a child-size bow and silex knifes silex being the steel of the Stone Age.

Modern when compared are the sandstone remains of the 17th century city wall, the construction of which can be investigated in detail for the first time.

The rescue excavations at the the Opera House car park have been ongoing for five months (an impressive photographic overview on the Zurich website). The dig will be completed by the end of January 2011, when the archaeologists have investigated the 3500 square metre area.

The Prehistory of Compassion: Neanderthals Cared Too

(Replica) Neanderthal Man at the Neanderthal Museum, Mettmann, Germany. - Photo by Erich FerdinandNew research by archaeologists at the University of York suggests that it is beyond reasonable doubt Neanderthals often misrepresented as furry, primitive caveman hobbling about had a deep seated sense of compassion.

Dr Penny Spikins, Andy Needham and Holly Rutherford from the universitys Department of Archaeology examined the archaeological record in search for evidence for compassionate acts in early humans. These illustrate the way emotions began to emerge in our ancestors six million years ago,which developed into the idea of ‘compassion’ we know today.

We have traditionally paid a lot of attention to how early humans thought about each other, but it may well be time to pay rather more attention to whether or not they ‘cared’, said Dr Spikins.

From Hominity to Humanity

Nowadays, ‘compassion’ which literally means ‘to suffer together’ is considered a great virtue by numerous philosophies and all the major religious traditions. But when did start to grow a desire to soother others’ distress? In the study ‘From hominity to humanity: Compassion from the earliest archaic to modern humans’, the researchers took on the unique challenge of charting key stages in the evolutionearly human’s emotional motivation to help others. They proposea four stage model for the development of human compassion:

Compassion is perhaps the most fundamental human emotion. It binds us together and can inspire us but it is also fragile and elusive

Stage 1 – It begins six million years ago when the common ancestor of humans and chimpanzees experienced the first awakenings of an empathy for others and motivation to help them, perhaps with a gesture of comfort or moving a branch to allow them to pass.

Stage 2 – The second stage from 1.8 million years ago sees compassion in Homo erectus beginning to be regulated as an emotion integrated with rational thought. Care of sick individuals represented an extensive compassionate investment while the emergence of special treatment of the dead suggested grief at the loss of a loved one and a desire to soothe others feelings.

Stage 3 – In Europe between around 500,000 and 40,000 years ago, early humans such as Homo heidelbergensis and Neanderthals developed deep-seated commitments to the welfare of others illustrated by a long adolescence and a dependence on hunting together.

There is evidence of the routine care of the injured or infirm over extended periods. These include the remains of a child with a congenital brain abnormality who was not abandoned but lived until five or six years old millennia later, the Spartans would have acted differently. A Neanderthal with a withered arm, deformed feet and blindness in one eye must have been cared for, perhaps for as long as twenty years.

Stage 4 – In modern humans starting 120,000 years ago, compassion was extended to strangers, animals, objects and abstract concepts.

Dr Penny Spikins, lead author of the study, said that new research developments, such as neuro-imaging, have enabled archaeologists to attempt a scientific explanation of what were once intangible feelings of ancient humans and that the research was only the first step in a much needed prehistoric archaeology of compassion.

Compassion is perhaps the most fundamental human emotion. It binds us together and can inspire us but it is also fragile and elusive, said Dr Spikins.

This apparent fragility makes addressing the evidence for the development of compassion in our most ancient ancestors a unique challenge, yet the archaeological record has an important story to tell about the prehistory of compassion.

Dr Spikins will give a free lecture, ‘Neanderthals in love: What can archaeology tell us about the feelings of ancient humans’, about the research at the University of York on Tuesday 19 October.

‘From hominity to humanity: Compassion from the earliest archaic to modern humans’ by Dr Penny Spikins, Andy Needham and Holly Rutherford is published in the journal Time and Mind. The study is also available as a book, ‘The Prehistory of Compassion’, available for purchase online.

Taming the Wolf – Domesticating the Dog

Little wolfThe first evidence for domesticated dogs has just got earlier with the recent dating of a dogs skull and teeth from Kesslerloch Cave in Switzerland. That puts the transition from wolf to dog to over 14,000 years ago. Previously, the earliest date was from a single jawbone that was found in a human grave at Oberkassel, in Germany, dating to about 13,000 years-ago. (There are earlier dates claimed for the first definite identification of dogs but these are usually discounted by experts).

The finds from Switzerland were uncovered in 1873 but it was only last year that archaeologists at Tubingen University in Germany recognised that the remains came from a dog rather than a wolf. The dating carried out on a tooth has revealed the animal died between 14,000 and 14,600 BP (before present).

These early dates are curious, as hunting strategies at that time would not necessarily require the assistance of dogs. Studies from northern France show that hunting was ambush based with animals speared as they passed through natural bottlenecks in the landscape, such as the Ahrensburg Valley. Here, the use of a spear-thrower increased the effectiveness of the weapon and the migrating reindeer died in great numbers. Interestingly, some people engraved their spear-throwers with scenes of the hunt but none shows the appearance of dogs. Indeed, in such a massacre, it is difficult to see how dogs would fit in at all and, yet, the remains from Switzerland suggest that they existed by this time.

It is likely that animals that chose to live with humans bred with other animals that adopted a similar lifestyle, replicating the traits that made the animal tolerant of humans. Slowly, the camp-wolves became the camp-dogs. In effect, the dog domesticated itself.

Stalking, the hunting method where a dog might have proved invaluable, came later. The warming climate at the end of the Ice Age caused large game animals to either die-out or move north and it was red deer and wild boar that took advantage of the advancing tree cover to expand their range. The people of the time changed their hunting strategy accordingly and the bow and arrow now became the weapon of choice. Dogs would have proved invaluable for stalking, flushing, and tracking dying animals. This is the time that we might expect people to have actively sought to domesticate the dog but, from the evidence at Switzerland, it had already happened, presumably without any human intervention. The change from wolf to dog requires a different explanation.

It is likely that wolves had always been aware of humans in the landscape. Scavenging human kill sites would have been a sure way of obtaining food and it is likely that this became the main survival strategy for a few packs. Over time, they may have ventured closer to human camps and even started to forage leftovers or eat any excrement that lay nearby. The people at the camp may have welcomed this cleaning service and tolerated the presence of the wolves. They may have even kept other, more dangerous predators at a safe distance.

Over time, it is likely that animals that chose to live with humans bred with other animals that adopted a similar lifestyle, replicating the traits that made the animal tolerant of humans. Slowly, the camp-wolves became the camp-dogs. In effect, the dog domesticated itself.

It is likely that the dogs did not remain in packs for long but divided themselves between the family groups of the hunters. Evidence from modern hunter-gather villages where semi-tame dogs roam, shows that these animals do not necessarily form packs but tend to organise themselves into groups of no more than three, which then adopt a particular dwelling (and its occupants) as their own. In the past, perhaps this was the reason that people began to interact with dogs on an individual basis and the first relationships, with which we are now so familiar, began.

A burial from Israel dating to around 11,000 BP contained an elderly woman with her hand resting on the flank of a puppy. This may be the first sign of the affection we still hold for dogs but it was not until much later, during the Mesolithic, that the esteem in which people held them becomes apparent.

In the earliest cemetery at Skateholm in southern Sweden, dating to around 5,000 BC, dogs were sometimes buried in the same graves as people. These were likely animals that were sacrificed to accompany their masters into the afterlife. Clearly, the dog was considered indispensable by some.

Hunting Dog

Other dogs were afforded their own grave and people gave them items such as tools and weapons that would usually be the preserve of a hunter. But then, perhaps this is exactly what these dogs were considered to be: hunters and, accordingly, they were buried as such.

At this time, grave wealth usually accumulated to the young and fit, likely reflecting their ability to provide food for the others. The dogs were no different: they provided food from the hunt and they were honoured in the same way. Moreover, this was a time before any other animal had been domesticated and the cognitive boundary between humans and animals was still fluid enough to be breached: sometimes human into animal and, on this occasion, animal into human. It was a very different way of seeing the world and is almost diametrically opposed to everything we think about animals.

It was not to last. Perhaps familiarity bred contempt, but in a later cemetery at Skateholm (and possibly dating to only a few hundred years after the first cemetery), dogs were afforded a separate area for their burials, before being excluded altogether. Dogs had moved from being equal to humans in the hunt to being subservient to their masters. Perhaps, as their usefulness increased, their worth actually diminished. We still retain something of this contradiction in our own relationship with dogs. They can be our closest companions but are also the source of our cruellest insults. A bitch can be both our best friend or our worst enemy.

There is even evidence that the minds of dogs have evolved since they have been interacting with humans. Observing and identifying the attention state of others was thought to be the sole preserve of humans and yet it appears to be something dogs can also accomplish. Anyone who has had their dog watch their every move when they walk towards the dog lead will know how this appears.

Our relationship with dogs has come a long way since the first wolves started to follow the camps of our Palaeolithic forebears. We may never know for sure what made these wild animals befriend us and change to become an altogether different species but I am sure that I am not alone in being extremely grateful that they did.

Iron Age Settlement and Roman Remains discovered at Sutton, South London

iron age foodEvidence of early Iron Age settlements and Roman remains have found at Sutton borough, south London.

The infant burials and animal remains uncovered across the site are believed to be over 2000 years old.

The discoveries were made by workmen laying the foundations for the new Stanley Park High School on the former site of Queen Mary’s Hospital.

The site lies less than 100m to the northwest of one of the largest 150m in diameter Late Bronze Age hilltop enclosures in southeast England, discovered in the early 20th century.

The archaeological remains are typical of a late Iron Age and early Roman farming settlement. Likely, the area was once a small farming community made up of earth and timber roundhouses with thatched roofs.

The excavations have also uncovered Romano-British enclosures, numerous postholes and pits, many containing multiple animal burials.

These animals which were either whole or partly dismembered appear to have been deliberately sacrificed and deposited in deep (up to 4m) pits cut into the chalk bed rock.

“A very large number of domestic animal skeletons have been recovered – including horses, cattle, pigs, sheep, goats and dogs, says Duncan Hawkins, lead archaeological consultant.

These animals which were either whole or partly dismembered appear to have been deliberately sacrificed and deposited in deep (up to 4m) pits cut into the chalk bed rock.

“This may represent some form of ‘closure’ ritual when the settlement passed out of use with the pits perhaps originally representing grain stores.”

Iron Age features, including a possible livestock pathway, shallow gullies and pits were also identified.

The finds will contribute to our understanding of early life in Britain and Greater London where much other evidence of these periods has been destroyed by earlier development (Top 10 Most Important Ancient Discoveries in London).

The school hopes that the discoveries can be shared with the pupils and used for inspiration in history lessons.

“Building work for our super new school continues while careful excavations are carried out. We are keen to learn more about the artefacts and stories behind them after they have been fully analysed – it will really help to bring ancient history to life for local children when they attend their new school,” says Graham Tope from Sutton Council.

Curious whatlife was like inIron Age Britain? Head to Cheshire this Saturday to celebrate the opening of their new prehistoric dwelling at the Iron Age Open Days. The free event will include demonstrations of Iron Age techniques such as making fire, bread and Iron Age jewellery, with an opportunity to have a go yourself.

Cheshire’s Oldest Standing Wall, Newest Roundhouse and Iron Age Open Days

The replica Iron Age Roundhouse, built by Chris Park from Acorn Education, will act as a teaching aid helping to bring archaeology to life for children.

The free event will include demonstrations of Iron Age techniques such as making fire, bread and Iron Age jewellery, with an opportunity to have a go yourself.

Round Houses were the dominant building style of late prehistoric Britain and would have been common to Cheshire throughout the Iron Age.

Archaeological remains of Iron Age round houses have been found in West Cheshire at Beeston Castle, Bruen Stapleford, Chester Business Park and even beneath the Roman Amphitheatre in Chester.

The construction of the Iron Age dwelling is just one project of many that Habitats and Hillforts is undertaking. Over a three year period, Habitats and Hillforts aim to conserve and enhance the string of six important Iron Age hillforts along the sandstone ridge Helsby, Woodhouse, Eddisbury, Kelsborrow, Beeston and Maiden Castle.

The fact that those in Cheshire can see those in North Wales might suggest a tribal identity theres far less intervisibility between Cheshire and Shropshire so maybe the people in Shropshire were from a different tribe.

Earlier this week, “Cheshire’s oldest standing wall” was discovered at the Eddisbury Hill when excavating the Iron Age hillfort’s entrance beneath a potato field. The entrance to the Eddisbury Hill hillfort, thought to be the most elaborate of the six, has seven sets of post holes, each as big as a tree trunk, as well as guard rooms.

I would say that this hillfort is as sophisticated as it gets in the Iron Age, the Northwich Guardian quotes Dan Garner, project officer at the Eddisbury Hill excavations.

The team has three more hillforts to excavate, after which they’ll try to determine how well the forts can see each other project ‘Hillfort Glow’.

Hillfort intervisibility is quite a hot topic at the moment, Garner said. We have computer software that shows where you can and cant see from each hillfort and a lot of our chain has good intervisibility with hillforts in North Wales. We dont really know where tribal boundaries are and intervisibility may define tribal areas. The fact that those in Cheshire can see those in North Wales might suggest a tribal identity theres far less intervisibility between Cheshire and Shropshire so maybe the people in Shropshire were from a different tribe.

Iron Age Open Day organised by Cheshire West and Chester Council’s Habitats and Hillforts project takes place this Saturday, 18 September at the Burwardsley Outdoor Education Centre (the old primary school). The opening of the Iron Age Roundhouse starts at 1.30pm.

Attractions at the open day include living history reenactments, willow weaving, site tours and having a go finding the remains of an Iron Age roundhouse at a mock archaeological dig.

There will also be demonstrations showing hurdle making and hedge laying and a chance to meet the Cheshire Badger Group and Cheshire Bat Group – and a BBQ and refreshments available.

Man’s First Domesticated Animals Were Tools Before Food

Primrose Hill - Wanna Play?Almost 32,000 years ago, man got its first puppy. Today still, humans have a special connection with animals, regardless if they are sitting on our laps, or – point on our plates. Why is it in our nature to accept of all kinds of creatures into our families and homes? What came first, the carbonade that would stay put, or the steadfast companion in the pursuit for game? And what if our first prehistoric attempts at art were no mindless doodling or sacred effigies, but an early publication of ‘Useful Beasts for Dummies’?

In a paper describing a new hypothesis for human evolution based on our tendency to nurture members of other species, palaeoanthropologist Pat Shipman argues that the human-animal link goes well beyond simple affection. She proposes that, over the last million years, the interdependency of early man with other animal species the animal connection” played a crucial in human evolution.

“Establishing an intimate connection to other animals is unique and universal to our species,” said Shipman. “No other mammal routinely adopts other species in the wild no gazelles take in baby cheetahs, no mountain lions raise baby deer,” Shipman said. “Every mouthful you feed to another species is one that your own children do not eat. On the face of it, caring for another species is maladaptive, so why do we humans do this?”

Shipman, a professor of biological anthropology at Penn State University, suggests that the animal connection was prompted by the invention of stone tools 2.6 million years ago. “Having sharp tools transformed wimpy human ancestors into effective predators who left many cut marks on the fossilised bones of their prey,” Shipman said.

Every mouthful you feed to another species is one that your own children do not eat. On the face of it, caring for another species is maladaptive, so why do we humans do this?”

This putour ancestorsin direct competition with other carnivores for prey.Humans who learned to observe and understand the behaviour of both their potential prey and competitors, were more successful at obtaining large amounts of meat without a doubt an evolutionary advantage.

The majority of early prehistoric art depicts animals. Shipman sees this as evidence that the evolutionary pressure to develop an external means of storing and transmitting information symbolic language came primarily from the need to share and handle what we knew about other species.

Though we cannot discover the earliest use of language itself, we can learn something from the earliest prehistoric art with unambiguous content. Nearly all of these artworks depict animals. Other potentially vital topics edible plants, water, tools or weapons, or relationships among humans are rarely if ever shown,” Shipman explains.

Shipman concludes that detailed information about animals became so advantageous that our ancestors began to nurture wild animals a practice that led to the domestication of the dog about 32,000 years ago.

Tanya and Hamster v 2.0

Surely, if insuring a steady supply of meat was the point of domesticating animals, as traditionally has been assumed, then dogs originally ferocious wolfs – would be a very poor choice as an early domesticated species? “Wolves eat so much meat themselves that raising them for food would be a losing proposition,”the professorpoints out.

Instead, Shipman suggests, the primary reason for domestication was to transform the animals we had been observing for millennia into living tools during their peak years, then only later using their meat as food. “As living tools, different domestic animals offer immense renewable resources for tasks such as tracking game, destroying rodents, protecting kin and goods, providing wool for warmth, moving humans and goods over long distances, and providing milk to human infants” she explains.

Domestication is a process that takes generations and puts selective pressure on abilities to observe, empathize, and communicate across species barriers. Once accomplished, the domestication of animals offers numerous advantages to those with these attributes.

“The animal connection is an ancient and fundamentally human characteristic that has brought our lineage huge benefits over time,” Shipman summarises. “Our connection with animals has been intimately involved with the evolution of two key human attributes tool making and language and with constructing the powerful ecological niche now held by modern humans.”

Pat Sherman’s paper is to be be published in the August 2010 issue of the journal Current Anthropology. In addition, Shipman has authored a book for the general public, titled The Animal Connection.

Neolithic Rock Art discovered at Cambridgeshire Quarry

prehistoric rock art cambridgeshore village of overA unique piece of 4,500-year-old rock art has been unearthed in the Cambridgeshire village of Over.

The prehistoric slab of sandstone is unlike anything previously found in Eastern England.

The hand-sized neolithic artefact, which possible dates back as far as 2,500 BC, was found at Needingworth Quarry by Open University student Susie Sinclair.

Intothe stone’ssurface, two pair of concentric circles are etched, typical of late Neolithic ‘Grooved Ware’ art.

Researchers do not know if the motif represents a type of meaningful art, or if it is nothing more than Neolithic doodling.

Examples of similar Grooved Ware art have been discovered at sites elsewhere in Britain, such as Skara Brae, but the Over stone is the first object with these scratch patterns found in Eastern England.

Dr. Chris Evans, Director of the Cambridge Archaeological Unit, explains: “It’s unique in Eastern England, with the nearest comparable example being the similar scratch patterns on a sandstone plaque from a Grooved Ware site in Leicestershire. Otherwise you would have to look to Wessex or Northern Britain and the much more formal Megalithic Art of the period.”

Neolithic Artefact with Grooved Ware art discovered at Needingworth Quarry, Over, CambridgeshireAs such, the sandstone slab may provide more information about connections between the different communities inhabiting the area 4,500 years ago.

At that time, the Needingworth area was a delta-like landscape, dominated by the River Great Ouse.

There would not have been one river, but many, carving up the valley into a series of small islands and wet marshlands.

Only in Medieval times the river was straightenedand thefenlands drained.

The Cambridge Archaeologial Unit has been excavating at the quarry for more than a decade.

So far Neolithic ‘pit settlements’, large groups of barrows and a Bronze Age fieldsystem extending for hundreds of hectares on both sides of the river have been identified in the Needingworth prehistoric landscape.

Since 2007, the quarry landis – quite appropriately – being restored to be part of a massivewetland bird reserve, the largest of its kind in Europe.

The stone will make its first public appearance since the discovery was made this Saturday (July 17th), when it will go on display at Over Village Carnival.

‘Rock Drawings were Prehistoric Movies’ – Most Obvious Archaeology Ever?

Old Art

My award for archaeology’s equivalent of an IgNoble prize goes to boffins at Cambridge University and Austria’s Sankt Poelten University, who have triumphantly announced that rock engravings from the Copper Age in Europe were ancient movies (as opposed to doodles).

Was this not a hopelessly obvious conclusion? Not to Cambridge’s Frederick Baker yesterday (June 29): “The cliff engravings…in our opinion are not just pictures but are part of an audiovisual performance.”

“There was still no moving image but (the pictures) created sequences like in animation,” adds Baker. “This was not just a treat for the eyes but also for the ears, as these rock engravings are especially found in locations with particular echoes. In this sense, the rock engravings are not just static images but pictures that created a story in the mind of the viewer: just like at the cinema.”

“There was no moving image but (the pictures) created sequences like in animation.”

Rock art was meant as a treat for the eyes? In caves that echoed? And the experience was ‘just like the cinema’? I’m not sure James Cameron would be too impressed with the comparison: look out next week, when the team plan to announce the Earth’s roundness, and that King Tut enjoyed using gold from time to time.

On a more promising note the team have launched the ‘Prehistoric Picture Project’ alongside Germany’s Bauhaus University. The project aims to recreate the ‘movies’, dating from 6,000 to 3,000 years old and frequently showing hunting, dancing or fighting scenes, as moving images. The project is being carried out in Valcamonica in Lombardy, Italy, where some 100,000 engravings are found.

5000-year-old Planning Application Holds Final Clue to Solve Stonehenge Riddle

Replica of the prehistoric deer hide discovered at Salisbury. - Image courtesy A. DobeOn Midsummers day, while more than 20,000 gathered at Stonehenge to celebrate the Summer Solstice,it was revealed a long-lost prehistoric documentwasdiscovered at Salisbury. The fragile deer hide document will put an end to all speculations asto the Neolithic monument’s purpose, revealing that theworld’s most famous stone circle was never a place of worship or a giant calendar. Rather, it was the centre of commerce for Britain’sBronze Agecivilization, as far as 5,000 years back.

According to entertainment website ‘NewsBiscuit’, after extensive study, Oxford University archaeologists concluded that the document is in fact a 5000-year-old failed planning application for a vast covered market place.The finds shows that 600stalls were to be constructed over a 200 acre site, with grazing facilities for 3,500 oxen and cart. The document further reveals that the Stonehenge development was never completed,for the planning application was turned down by the ‘Local Council of Elders’. One of the reasons given for this was that the planners ‘did not think that the developers used of imported Welsh stone was sympathetic to, or in keeping with, local architecture’, as well asserious concerns over increased oxen traffic.

The planners ‘did not think that the developers used of imported Welsh stone was sympathetic to, or in keeping with, local architecture’.

The find does not only solve the mystery of Stonehenge’s function, but also offers new insight into the history of Druidism. Dr Amy Bogaard told NewsBiscuit: “We now know that Druidism is not a pagan religion at all. ‘Druids’ was actually the brand name of a chain of prehistoric pharmacists, the forerunner of their modern day counterpart ‘Boots'”. Further detailson the ‘discovery’ and ‘research’ are available on the NewsBiscuit website.

The team of experts nowhope that now they’ve solved the mystery of Stonehenge,the government will reconsider contributing 10 million towards the new visitor centre planned on the site.The visitor centre,funding for which was recently scrapped by the LibDem coalition, willcommemorate what was once the most important site for the Salisbury Plain economy.
