Investigadores analizarán si hubo ocupación humana del Neolítico en cinco enclaves extremeños

1/2. Una de las pinturas rupestre que se estudiarán en los próximos días
Estudiarán las zonas de La Zarza, Llerena, Hornachos, Fuentes de León y Cabeza del Buey. En el proyecto colaborarán geólogos, físicos, químicos, botánicos y arqueólogos

Extremadura se prepara para vivir, en poco menos de dos meses, uno de los estudios más intensos de arte rupestre que se ha llevado a cabo en la región.

Arqueólogos y profesionales de diferentes sectores colaborarán en sintonía en el proyecto ‘Contextos del Arte Rupestre Esquemático en la provincia de Badajoz’, subvencionado por la Diputación de Badajoz.

Este estudio tratará de analizar, mediante tecnologías de última generación, dataciones cronológicas y hacer sondeos valorativos en abrigos (cuevas naturales de pequeña profundidad) que indiquen si ha habido ocupación humana

Los investigadores utilizarán maquinarias de pigmentos de espectrometría Raman para tratar de conseguir analizar líquenes en los enclaves de La Zarza, Llerena, Hornachos, Fuentes de León y Cabeza del Buey, grandes focos del arte rupestre en Extremadura. [...]

Escavações em Proença-a-Nova revelam técnicas de construção inovadoras

Mamoa do Cabeço da Anta.
As escavações no campo arqueológico de Proença-a-Nova, no distrito de Castelo Branco, estão a revelar técnicas de construção em sepulturas megalíticas até agora desconhecidas, com recurso a argamassa, disse hoje à agência Lusa o arqueólogo João Caninas.

28/08/15. "Temos aqui uma construção completa que combina argilas com vários tipos de composição e estruturas em pedra. Podemos estar perante o protótipo do primeiro muro de dois paramentos e enchimento interno, o que mais tarde, no Calcolítico, surge em povoados fortificados", disse João Caninas.

O arqueólogo falava hoje durante uma conferência de imprensa realizada no campo arqueológico de Proença-a-Nova, cuja quarta edição das escavações se iniciou a 03 de agosto e termina este sábado.

Este responsável realçou que é preciso aguardar pelos resultados laboratoriais finais.

Contudo, adiantou que da análise química preliminar feita aos materiais encontrados na mamoa do Cabeço da Anta, "provavelmente, surge aqui a primeira argamassa" utilizada na construção deste tipo de monumentos. [...] Noticias ao Minuto

Archaeologists make surprise find in north-east Poland

Radio Poland [August 12, 2015]. Archaeologists have discovered traces of so-called Bell Beaker culture in the Podlaskie region dating back several thousand years.

"It's quite a sensational discovery," Dariusz Manasterski, of the Institute of Archaeology at the University of Warsaw, said. It had previously been thought that the culture reached no further than what is now southern Poland.

Excavations were carried out over a week at an archaeological site in Supraśl, near Białystok in north-east Poland. Fragments of pottery, human bones and stone tools, for example a hatchet, have been found.

The dig is being led by archaeologists from the University of Warsaw and the Museum of Podlasie in Białystok.

The emergence of the Bell Beaker culture is dated to about 4-5,000 years ago. It evolved in Western Europe, on the Iberian Peninsula, and its name is associated with characteristic dishes in the shape of an inverted bell.   /   Link 2

Remains of newborn child who died 5000 years ago found in Orkney

The remains of a newborn child who died 5000 years ago have been found by archaeologists in Orkney.

August 25, 2015. The bones were discovered earlier this week during a dig at the Ness of Brodgar, a prehistoric site near the town of Stromess.

Experts described their condition as “remarkable” but could not say whether they belonged to a boy or a girl.

They added that the “careful” burial the newborn was given was unusual for an era when so many children died at a young age.

A spokesman for the Ness of Brodgar excavation said: “Five thousand years ago, a child who died at or near birth was buried [there].

"The discovery was made by Andy Boyar, an experienced excavator who was digging at the south end of a building.

“The fragile skeleton was lying on its side in a flexed position and Andy excavated them with exquisite care. They have been gently cleaned and laid out to see how much of the skeleton has survived.

“The preservation of the bones is remarkable. Even with adult skeletons on archaeological sites it is very easy to miss the small bones of the hands and feet. [...]

'Ötzi-Walk:' Hike like in the Stone Age

Three hikers, two weeks, one rule: use Stone Age appropriate equipment only. To promote an exhibition, a museum sent two men and one woman on the "Ötzi-Walk." But they didn't plan with a stint of bad summer weather. 

The "Ötzi-Walkers" are not actually walking. They are huddled in a miserable little hut without walls in the woods just off a main road somewhere in North-Rhine Westphalia. They are staring at the rain that seems to be coming down heavier by the minute - which is good in so far as the louder it gets, the less you can hear the white noise coming from the autobahn that bothered them all night.

That's right - All night. The trio, clad in linen and leather, slept in the hut as well, even though it got pretty chilly. But that's part of the deal.

During the 15-day "Ötzi-Walk," Lukas Heinen, Marco Hocke and his wife Veronika Hocke were to hike from Detmold to Bonn. It's an usual promotion project for the "Revolution New Stone Age" exhibition that the LVR Museum Bonn will display in its three locations in Bonn, Herne and Detmold starting September 5.

Prehistoric climate variability a key factor in human evolution, say scientists

In a newly published paper, Smithsonian anthropologist Richard Potts and anthropologist J. Tyler Faith of the University of Queensland, Australia, relate in detail the results of years of study defining a predictive model of climate and environmental variability correlated with key changes or stages in human evolution in East Africa and China. The study, in concert with previous studies, challenges some long-held theories about what has driven the mechanisms of human evolution.

The model, say the authors, predicts eight long periods of environmental instability in East Africa correlated with times of hominin evolutionary innovations as a result of natural selection resulting from the variability. The research also included data derived from palynological study in the Nihewan Basin of China, where evidence suggests that early humans survived and successfully adapted to a new, radically changed environment.

Plea made to save last remains of oldest bog road

Conservationists are pleading for emergency action to stop destruction of the country’s oldest known bog road.

Much of the 3,000-year-old wooden roadway or togher, discovered intact at Mayne Bog in Co Westmeath in 2005, was destroyed during commercial peat extraction over the summer.

An Taisce has criticised the National Monuments Service for failing to secure a preservation order for the Bronze Age site and is now calling on Heather Humphreys, the arts and heritage minister who has responsibility for the service, to make an urgent order on what’s left of it.

An Taisce’s calls have the backing of the recently retired director of the National Museum of Ireland, Patrick Wallace, who said of the road: “Its possible destruction would be an international calamity.”
The road was first spotted in 2005 and it was inspected that year by the National Monuments Service which arranged for a partial excavation the following year.

Those limited investigations found the road dated back to 1200BC-820BC and was made of planks of oak some 4.4m wide, running for at least 675m. [...]  Irish Examiner

Buried treasure - 3,500 year old urn found buried in the Peak District National Park

Remains of the rescued 3,500 year old pot (height 22cm)

August 27, 2015. An ancient earthen ware pot containing cremated human remains has been discovered by a worker repairing a footpath in the Peak District National Park.

The urn, believed to date back about 3500 years, was found on the Roaches nature reserve, near Leek, by contractor Kieran Fogarty whilst digging a trench to reinforce a popular footpath.

Ken Smith, cultural heritage manager for the Peak District National Park, said: "Kieran did exactly the right thing – by contacting us so quickly we were able to get out to the site and identify what he had uncovered.

"From the type and style of the pot, and its contents, we identified it as a Bronze Age cremation urn and knew we needed to move quickly to conserve the remains."[...] Ashbourne News Telegraph / Link 2
