Un estudio arqueológico asocia la presencia de pinturas rupestres con una buena acústica

La elección de un lugar para realizar pinturas rupestres durante el Paleolítico guarda relación con la existencia de una buena acústica para "incrementar el impacto" de los rituales, según indica un trabajo de la Universidad de Barcelona (UB) y la Universidad de Zaragoza.

El trabajo ha utilizado métodos de la arqueoacústica, un campo de investigación emergente sobre el uso que hacían del sonido las sociedades del pasado, y se ha centrado en los yacimientos que existen en el barranco de la Valltorta, en Castellón.

Los investigadores concluyen que estas pinturas, que van del 9.000 al 6.000 a.C., se ubican en el abrigo de los barrancos con mejor sonoridad que las zonas que no están decoradas, lo que sugiere que la elección de los lugares estaba relacionada con la acústica de cada lugar.

El estudio lo publica la revista 'Journal of Archaeological Science', y en él los investigadores Carlos García y Margarita Díaz-Andreu grabaron y midieron los sonidos producidos en diferentes zonas del barranco, ya fueran realizados por la voz humana, silbatos o aplausos.

Los resultados puntualizan además que la acústica de los abrigos con más pinturas —Saltadora, Cavalls y Civil— es incluso mejor cuando el sonido se produce de cara al barranco, mientras que los lugares con menos pinturas el sonido es mejor de cara a la pared.

La hipótesis, por tanto, es que en los lugares con menos decoración se practicaban rituales individuales mirando hacia la pared, mientras que en los abrigos con más pinturas tenían lugar rituales colectivos que se hacían de cara al fondo del barranco, donde se podría haber reunido la comunidad.

Adicionalmente, los investigadores también han observado que los tres lugares más decorados tienen ecos que van en diferentes direcciones, hasta cubrir la totalidad del barranco.

Kennewick Man from coast, anthropologist says

Kennewick Man apparently was just a visitor to the area of present-day Kennewick, the latest results of the study of his skeleton indicate.

Douglas Owsley, a Smithsonian Institute anthropologist, gave an update of scientific findings Wednesday at Archaeology Days at Grant County Public Utility District in Beverly. He led the court battle to study the 9,300-year-old skeleton found along the Columbia River in 1996.

An isotopic analysis of Kennewick Man's bones shows he most likely was eating a coastal diet based on marine proteins, such as seals, Owsley said.

"It's very confusing and very unexpected," he said.

The study determined a nitrogen isotope value for his bones, which would be low if he were eating animals that grazed, but high if he were eating a diet of meat higher up the food chain.

Grazers such as deer and elk "were just not in his world," Owsley said [...] tri-cityherald.com/

Actualización 02-11-12. Burke archaeologist challenges Smithsonian over Kennewick Man
 A Burke Museum archaeologist is raising the alarm over the Smithsonian's science. Their mistake? No peer review.
The discovery of Kennewick Man, the name given to the 9,200 year-old skeleton unearthed in southern Washington nearly a decade ago, has unearthed plenty of questions among anthropologists and tribal members about what Kennewick Man's life might have been like. To Burke Museum anthropological archaeologist Peter Lape though, the biggest question at hand is whether peer review, a time-honored scientific practice, is being ignored by leading forensic anthropologist Douglas Owsley, whose team has been the only one allowed to study Kennewick Man's bones since they were discovered in the mid-90s...

Late Bronze Age Hoard Discovered in Jersey

A Late Bronze Age hoard has been uncovered in a field in the Parish of Trinity, Jersey just months after the biggest Celtic coin hoard of all time was unearthed in the Island.

It is thought that the find is a Late Bronze Age pottery vessel (around 1000 BC) containing what appear to be weapons and tools. At present, two socketed axe heads have been identified but it is not yet confirmed what else is contained within the vessel.

Curator of Archaeology at Jersey Museum, Olga Finch said, ‘For there to have been two archaeologically important finds in the space of just a few months illustrates the extent of Jersey’s rich cultural heritage and how significant the Island’s archaeology is. There has been a number of Late Bronze Age hoards found in Jersey already, some of which have been founder’s hoards which would have been recovered and melted down into metal. We are lucky in that this particular find appears to be mostly intact, which makes it quite rare and should help us to learn more about why the find was buried.’[...] jersey.isle-news.com
