2009-07-02 – Germania: Flauto preistorico (Germany, Prehistoric Flute)

GERMANIA: TROVATO UN FLAUTO PREISTORICO DI 35. 000 ANNI

(AGI) – Parigi, 24 giu. – La Germania si sta rivelando una miniera di reperti preistorici. Un flauto risalente a 35.000 anni fa e’ stato ritrovato vicino Ulm nella valle di Ach, nel Sud del Paese nello stesso sito dove e’ stata rinvenuta la cosiddetta ‘Venere di Hohle Fels’ una statuina di avorio raffigurante una donna appena abbozzata. La scoperta’ e’ frutto del lavoro di un’equipe di archeologi guidati da Nicholas Conard. Secondo quanto riferisce Nature il flauto, realizzato con un osso di avvoltoio ha cinque buchi, e’ lungo 22 centimetri e si puo’ suonare come uno strumento attuale.

Excavations in the summer of 2008 at the sites of Hohle Fels and Vogelherd produced new evidence for Paleolithic music in the form of the remains of one nearly complete bone flute and isolated small fragments of three ivory flutes.

 

 

 

 

 

The most significant of these finds, a nearly complete bone flute, was recovered in the basal Aurignacian deposits at Hohle Fels Cave in the Ach Valley, 20 km west of Ulm. The flute was found in 12 pieces. The fragments were distributed over a vertical distance of 3 cm over a horizontal area of about 10 x 20 cm. This flute is by far the most complete of all of the musical instruments thus far recovered from the caves of Swabia.

The preserved portion of the bone flute from Hohle Fels has a length of 21.8 cm and a diameter of about 8 mm. The flute preserves five finger holes. The surfaces of the flute and the structure of the bone are in excellent condition and reveal many details about the manufacture of the flute. The maker carved two deep, V-shaped notches into one end of the instrument, presumably to form the proximal end of the flute into which the musician blew. The find density in this stratum is moderately high with much flint knapping debris, worked bone and ivory, bones of horse, reindeer, mammoth, cave bear, ibex, as well as burnt bone. No diagnostic human bones have been found in deposits of the Swabian Aurignacian, but we assume that modern humans produced the artifacts from the basal Aurignacian deposits shortly after their arrival in the region following a migration up the Danube Corridor.

The maker of the flute carved the instrument from the radius of a griffon vulture (Gyps fulvus). This species has a wingspan between 230 and 265 cm and provides bones ideal for large flutes. Griffon vultures and other vultures are documented in the Upper Paleolithic sediments of the Swabian caves.

The 2008 excavations at Hohle Fels also recovered two small fragments of what are almost certainly two ivory flutes from the basal Aurignacian. The different dimensions of the fragments indicate that the two finds are not from the same instrument. Excavators at Vogelherd in the Lone Valley 25 km northwest of Ulm recovered another isolated fragment of another ivory flute.

The technology for making an ivory flute is much more complicated than making a flute from a bird bone. This process requires forming the rough shape along the long axis of a naturally curved piece of ivory, splitting it open along one of the bedding plains in the ivory, carefully hollowing out the halves, carving the holes, and then rejoining the halves of the flute with an air-tight seal. Given the tendency of delicate ivory artifacts to break into many pieces, it is not unusual to find isolated pieces of such artifacts.

The 10 radiocarbon dates from the basal Aurignacian fall between 31 and 40 ka BP. Available calibrations and independent controls using other methods indicate that the flutes from Hohle Fels predate 35,000 calendar years ago. Apart from the caves of the Swabian Jura there is no convincing evidence for musical instruments predating 30 ka BP.

These finds demonstrate that music played an important role in Aurignacian life in the Ach and Lone valleys of southwestern Germany. Most of these flutes are from archaeological contexts containing an abundance of organic and lithic artifacts, hunted fauna, and burnt bone. This evidence suggests that the inhabitants of the sites played musical instruments in diverse social and cultural contexts and that flutes were discarded with many other forms of occupational debris. In the case of Hohle Fels, the location of the bone flute in a thin archaeological horizon only 70 cm away from a female figurine of similar age suggests that a possible contextual link exists between these two finds.

The flutes from Hohle Fels, Vogelherd and previous finds from nearby Geißenklösterle Cave demonstrate that a musical tradition existed in the cultural repertoire of the Aurignacian around the time modern humans settled in the Upper Danube region. The development of a musical tradition in the Aurignacian accompanied the development of the early figurative art and numerous innovations, including a wide array of new forms of personal ornaments, as well as new lithic and organic technologies. The presence of music in the lives of Upper Paleolithic peoples did not directly produce a more effective subsistence economy and greater reproductive success, but music seems to have contributed to improved social cohesion and new forms of communication, which indirectly contributed to demographic expansion of modern humans relative to the culturally more conservative Neanderthal populations.

The flutes from the caves of the Swabian Jura constitute a key part a major exhibit in Stuttgart entitled Ice Age Art and Culture, which will run from September 18, 2009 – January 10, 2010.

More information: The authors of the paper “New flutes document the earliest musical tradition in southwestern Germany” are Nicholas J. Conard Maria Malina and Susanne C. Münzel. The paper will be published as Advance online publication in Nature, June 25, 2009.

2009-06-20 – Spagna, Teruel: trovato nuovo ornitopode (Spain, new Ornithopod) (Espana, nuevo ornitópodo)

Paleontologists of  Dinópolis Foundation have found the back leg of new a dinosaur ornithopod of small size near a vertebra and a tooth of the “Turiasaurus riodevensis”. These remains are been founded in the deposit going back to 145 million years ago of Barrihonda-El Chimney of Riodeva, in Teruel , Spain.

  • Hallan la pata trasera de un nuevo dinosaurio de pequeño tamaño
  • También han localizado una vértebra y un diente del ‘Turiasaurus riodevensis’

La pata de un nuevo dinosaurio, seguramente un ornitópodo de hace unos 145 millones de años, es el último tesoro paleontológico encontrado en el yacimiento de Barrihonda-El Humero de Riodeva, en Teruel, en las excavaciones de este año de la Fundación Dinópolis.

Junto con este fósil, ya han aparecido una vértebra y un diente más del gigantesco ‘Turiasaurus riodevensis’, considerado el más grande de Europa, cuyo esqueleto cada vez está más completo.

El hallazgo de la pata trasera del nuevo dinosaurio fue una auténtica sorpresa, como explica Luis Alcalá, director de la Fundación Dinópolis: “Apareció el primer día de las excavaciones en el yacimiento, que es una explanada del tamaño de un campo de baloncesto. Estaban limpiando la zona cuando toparon con el fósil, a unos cuatro metros del ‘Turiasaurus’. Enseguida vimos que era otro dinosaurio nuevo, del grupo de los ornitópodos, pero aún no sabemos de qué especie”, explica el paleontólogo.

Los ornitópodos eran dinosaurios de tamaño pequeño, unos cinco metros incluida la cola, que comían plantas y andaban a cuatro patas. No tenían armadura, ni cuernos ni colmillos; posiblemente las únicas defensas con que contaron fueron su pico grande y fuerte y la cresta (aunque solo algunos).

A pocos metros de este ejemplar, se ha encontrado una vértebra del gigante de Riodeva, así como otro diente. Completar lo más posible su esqueleto es el objetivo prioritario del proyecto de la excavación, cuando ya se tiene un 45%. También han salido a la luz restos de carnívoros, entre ellos uno de grandes dimensiones.

A falta de realizar un exhaustivo estudio de los últimos huesos, el director de la Fundación plantea que podría haber habido una avalancha o algún otro suceso natural que provocó la muerte simultánea de varios dinosaurios, debido a la gran acumulación de huesos que hay en el mismo sitio.

Hace unas semanas, los investigadores confirmaron que animales carnívoros, alguno de grandes dimensiones, habían devorado a ‘Turiasaurus’, en cuyos restos de la cadera se identificaron perforaciones hechas por las mordeduras.

Las excavaciones en este yacimiento continuarán hasta el 20 de julio, si sigue este ritmo de hallazgos. “No podemos sacar más fósiles de los que podemos estudiar en los ocho meses siguientes. Y también hay que preparar el material”, comenta Alcalá.

Hasta ahora, el yacimiento de Barrihonda-El Humero está siendo una mina. Junto con el gigante de Europa y varios carnívoros, se había encontrado un estegosaurio, y la lista aumenta ahora con el nuevo ornitópodo.

2009-06-15 – Mare del Nord: pescati resti di “Uomo di Neanderthal” (North Sea, Homo neanderthalensis)

SCIENZA: FOSSILE DEL MARE DEL NORD APPARTENEVA A UOMO NEANDERTHAL

(ASCA) – Roma, 15 giu – Un frammento di osso recuperato nelle acque del mare del Nord apparteneva ad un uomo di Neanderthal. Secondo quanto rende noto il sito web della Bbc, il primo ritrovamento del genere, e’ stato confermato dall’analisi degli isotopi del fossile, che risale a 60 mila anni fa ed e’ appartenuto ad un uomo la cui alimentazione era carnivora, caratteristiche specifiche dell’uomo di Neanderthal.

Il Mare del Nord e’ una delle aree piu’ ricche del pianeta per ritrovamenti di fossili di mammiferi, dovuto al fatto che nelle ere passate i livelli dell’acqua erano sostanzialmente piu’ bassi di quelli odierni con vaste zone di terraferma.

Qui sono stati ritrovati molti reperti di animali dell’era glaciale, come cavalli, renne, rinoceronti e mammuth.

Il frammento di osso frontale scoperto a Leiden, nei Paesi Bassi, e’ il primo conosciuto reperto umano ”arcaico” recuperato dalle acque del mare in tutto il mondo. Fu ritrovato fra resti di altri animali e manufatti di pietra a 15 chilometri al largo delle coste olandesi nel 2001. Gli studi sui reperti sono stati condotti dal professor Jean-Jacques Hublin, del Max Planck Institute for Evolutionary Anthropology di Leipzig, in Germania. ”Anche avendo un piccolo frammento di disposizione, possiamo ora sicuramente confermare la sua appartenenza ad un uomo di Neanderthal”, ha detto Hublin alla Bbc.

L’uomo di Neanderthal e’ vissuto nel periodo detto paleolitico, fra 130 mila e 25-30 mila anni fa in Europa, Africa e Asia

Sea gives up Neanderthal fossil

By Paul Rincon
Science reporter, BBC News

Neanderthal frontal bone (Museum of Antiquities in Leiden)

The fragment of skull belonged to a young adult male

Part of a Neanderthal man’s skull has been dredged up from the North Sea, in the first confirmed find of its kind.

Scientists in Leiden, in the Netherlands, have unveiled the specimen – a fragment from the front of a skull belonging to a young adult male.

Analysis of chemical “isotopes” in the 60,000-year-old fossil suggest a carnivorous diet, matching results from other Neanderthal specimens.

The North Sea is one of the world’s richest areas for mammal fossils.

But the remains of ancient humans are scarce; this is the first known specimen to have been recovered from the sea bed anywhere in the world.

For most of the last half million years, sea levels were substantially lower than they are today.

Significant areas of the North Sea were, at times, dry land. Criss-crossed by river systems, with wide valleys, lakes and floodplains, these were rich habitats for large herds of ice age mammals such as horse, reindeer, woolly rhino and mammoth.

Even with this rather limited fragment of skull, it is possible to securely identify this as Neanderthal
Jean-Jacques Hublin, Max Planck Institute

Their fossilised remains are brought ashore in large numbers each year by fishing trawlers and other dredging operations.

According to Professor Chris Stringer, from London’s Natural History Museum, some fishermen now concentrate on collecting fossils rather than their traditional catch.

“There were mammoth fossils collected off the Norfolk and Suffolk coasts 150 years ago, so we’ve known for some time there was material down there that was of this age, or even older,” Professor Stringer, a museum research leader, told BBC News. Indeed, some of the fossil material from the North Sea dates to the Cromerian stage, between 866,000 and 478,000 years ago.

It had been “only a matter of time”, he said, before a human fossil came to light.

Professor Stringer added: “The key thing for the future is getting this material in a better context.

“It would be great if we could get the technology one day to go down and search (in the sea floor) where we can obtain the dating, associated materials and other information we would get if we were excavating on land.”

Private collection

Neanderthals (Homo neanderthalensis) were our close evolutionary cousins; they appear in the fossil record some 400,000 years ago.

These resourceful, physically powerful hunter-gatherers dominated a wide range spanning Britain and Iberia in the west, Israel in the south and Siberia in the east.

Our own species, Homo sapiens, evolved in Africa, and replaced the Neanderthals after entering Europe about 40,000 years ago.

The specimen was found among animal remains and stone artefacts dredged up 15km off the coast of the Netherlands in 2001.

The fragment was spotted by Luc Anthonis, a private fossil collector from Belgium, in the sieving debris of a shell-dredging operation.

Study of the specimen has been led by Professor Jean-Jacques Hublin, from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.

“Even with this rather limited fragment of skull, it is possible to securely identify this as Neanderthal,” Professor Hublin told BBC News.

For instance, the thick bony ridge above the eyes – known as a supraorbital torus – is typical of the species, he said.

The fragment’s shape best matches the frontal bones of late Pleistocene examples of this human species, particularly the specimens known as La Chapelle-aux-Saints and La Ferrassie 1.

These examples, which were both unearthed in France, date from between 50,000 and 60,000 years ago.

The North Sea fossil also bears a lesion caused by a benign tumour – an epidermoid cyst – of a type very rare in humans today.

The research links up with the Ancient Human Occupation of Britain 2 (AHOB 2) project, which aims to set Britain’s prehistory in a European context. Dutch archaeologist Wil Roebroeks, a collaborator on this study, is a member of the AHOB 2 research team.

Extreme ways

Dr Mike Richards, from the Max Planck Institute in Leipzig, analysed different forms, or isotopes, of the elements nitrogen and carbon in the fossilised bone. This shed light on the types of foods eaten by this young male.

The results show he was an extreme carnivore, surviving on a diet consisting largely of meat.

“High in the food chain, they must have been quite rare on the ground compared to other mammals, which explains their rarity to some degree,” said Wil Roebroeks from the University of Leiden.

The results of the stable isotope analysis fit with what is known about other examples of this species, though other research suggests that in Gibraltar, on the southern coast of Iberia, some Neanderthals were exploiting marine resources, including dolphins, monk seals and mussels.

Researchers decided against carbon dating the specimen; this requires the preservation of a protein called collagen.

Professor Hublin explained that while there was some collagen left in the bone, scientists would have needed to destroy approximately half of the fossil in order to obtain enough for dating.

Professor Roebroeks told BBC News: “Dutch scientists – geologists and archaeologists alike – are hoping this find will convince governmental agencies that the Netherlands needs to invest much more in that… archive of Pleistocene sediments off our coast – and off the coast of Britain.”

He said this submerged repository contained “high resolution information on past climate change and its environmental consequences, points of reference for how rivers ‘worked’ before any human interference and now, as this find shows, remains of people who once roamed these landscapes.”

Professor Hublin said the individual was living at the extreme edge of the Neanderthals’ northern range, where the relatively cold environment would have challenged their capabilities to the limit. Neanderthal remains have been found at only two sites this far north.

“What we have here is a marginal population, probably with low numbers of people,” Professor Hublin explained.

“It’s quite fascinating to see that these people were able to cope with the environment and be so successful in an ecological niche which was not the initial niche for humans.”

While these hunting grounds would at times have provided plentiful sources of meat for a top carnivore, Neanderthals living in these areas would also have been at the mercy of fluctuations in the numbers of big game animals.

Periodic dips in populations of mammals such as reindeer could have caused local extinctions of Neanderthal groups which hunted them, Dr Hublin explained.

2009-06-06 – Serbia: ritrovato scheletro di mammuth (Mammoth skeleton)

Serbia’s Million-Year-Old Mammoth Skeleton

Local media reported on Wednesday that a finely preserved skeleton of a mammoth believed to be around one million years old was uncovered near an archaeological site in eastern Serbia, AFP reported.

An archeologist works on a recently unearthed skeleton of a mammoth at the open pit coal mine in Kostolac, some 95 km east of Belgrade, Thursday, June 4, 2009. A skeleton of a so-called southern mammoth or mammuthus meridionalis, originating from northern Africa believed to be about one million years old has been unearthed in eastern Serbia. The mammoth was more than 4 meters (13 feet) high, 5 meters (16 feet) long and weighed more than 10 tons, Miomir Korac from the Archaeology Institute says. Another mammoth skeleton, from a much later period, was discovered at a factory in Serbia in 1996 and was named Kika. (AP Photo/Srdjan Ilic)

Archaeologist Miomir Korac said the skeleton was uncovered during ongoing excavations of the site at Viminacium, a Roman military settlement on the Danube river.

“The skeleton is extremely well preserved, with only a slightly damaged skull,” said Zoran Markovic of Serbia’s Nature museum.

Markovic told B92 television the skeleton is believed to be about one million years old, based on the layers of the grounds where it was uncovered.

The mammoth was estimated to be over 13 feet and possibly weighing up to 10 tons, according to experts.

B92 reported that the animal could have died near the Danube on its way from northern Africa and to southern Europe.

Fossil remains of a mammoth were found near the northern Serbian town Kikinda in 1996. The half a million year old mammoth was named Kika and soon became a tourist attraction.

Local authorities will organize a “Mammoth fest” on September 6 to celebrate “Kika’s 12th birthday,” according to its Website www.kika-mamut.com.

2009-06-04 – Centenario del museo geologico di Bologna senza “Ciro”

La Soprintendenza rifiuta di esporre il piccolo Ciro

BOLOGNA- La Soprintendenza di Salerno nega l’esposizione del fossile di dinosauro rinvenuto sul territorio per la celebrazione dei 100 anni del museo geologico emiliano.In occasione del centenario dell’arrivo del reperto in citta’, si terranno anche un convegno internazionale sulla Paleobiogeografia dei vertebrati, con antropologi e studiosi provenienti anche da Parigi e dall’Alberta e la mostra ‘I dinosauri italiani’. L’esposizione, ospitata dal 5 settembre all’11 gennaio 2010, al museo Geologico e’ composta da una settantina di pezzi, tra cui ‘Antonio’, il dinosauro di 5 metri con il becco d’anatra, conservato a Trieste, che per l’occasione arrivera’ sotto le Due Torri. Molto probabilemente non ci sara’, invece, ‘Ciro’, il piccolo dinosauro fossile rinvenuto tra Campobasso e Salerno. “La sovrintendenza di Salerno – ha spiegato Vai – ci ha negato il trasferimento, mi sono anche rivolto al ministro Bondi, ma non ho ancora avuto risposta, eppure sono convinto che il reperto, per quanto fragile e delicato, si possa trasportare senza problemi”. Se l’ok alla trasferta emiliana di ‘Ciro’ non ci sara’, alla mostra bolognese sara’ comunque esposto un modello del reperto originale che, sostiene Vai, “e’ tenuto nei magazzini della Sovrintendenza”.

New Hominid 12 Million Years Old Found In Spain, With ‘Modern’ Facial Features

ScienceDaily (June 2, 2009) — Researchers have discovered a fossilized face and jaw from a previously unknown hominoid primate genus in Spain dating to the Middle Miocene era, roughly 12 million years ago. Nicknamed “Lluc,” the male bears a strikingly “modern” facial appearance with a flat face, rather than a protruding one. The finding sheds important new light on the evolutionary development of hominids, including orangutans, chimpanzees, bonobos, gorillas and humans.

In a study appearing in the Proceedings of the National Academy of Sciences, Salvador Moyà-Solà, director of the Institut Català de Paleontologia (ICP) at the Universitat Autònoma de Barcelona, and colleagues present evidence for the new genus and species, dubbed Anoiapithecus brevirostris. The scientific name is derived from the region where the fossil was found (l’Anoia) and also from its “modern” facial morphology, characterized by a very short face.

 The research team at the ICP also includes collaborator David M. Alba, predoctoral researcher Sergio Almécija, postdoctoral researcher Isaac Casanovas, researcher Meike Köhler, postdoctoral researcher Soledad De Esteban, collaborator Josep M. Robles, curator Jordi Galindo, and predoctoral researcher Josep Fortuny.

Their findings are based on a partial cranium that preserves most of the face and the associated mandible. The cranium was unearthed in 2004 in the fossil-rich area of Abocador de Can Mata (els Hostalets de Pierola, l’Anoia, Barcelona), where remains of other fossilized hominid species have been found. Preparing the fossil for study was a complicated process, due to the fragility of the remains. But once the material was available for analysis, the results were surprising: The specimen (IPS43000) combined a set of features that, until now, had never been found in the fossil record.

Anoiapithecus displays a very modern facial morphology, with a muzzle prognathism (i.e., protrusion of the jaw) so reduced that, within the family Hominidae, scientists can only find comparable values within the genus Homo, whereas the remaining great apes are notoriously more prognathic (i.e., having jaws that project forward markedly). The extraordinary resemblance does not indicate that Anoiapithecus has any relationship with Homo, the researchers note. However, the similarity might be a case of evolutionary convergence, where two species evolving separately share common features.

Lluc’s discovery may also hold an important clue to the geographical origin of the hominid family. Some scientists have suspected that a group of primitive hominoids known as kenyapithecines (recorded from the Middle Miocene of Africa and Eurasia) might have been the ancestral group that all hominids came from. The detailed morphological study of the cranial remains of Lluc showed that, together with the modern anatomical features of hominids (e.g., nasal aperture wide at the base, high zygomatic rood, deep palate), it displays a set of primitive features, such as thick dental enamel, teeth with globulous cusps, very robust mandible and very procumbent premaxilla. These features characterize a group of primitive hominoids from the African Middle Miocene, known as afropithecids.

Interestingly, in addition to having a mixture of hominid and primitive afropithecid features, Lluc displays other characteristics, such as a very anterior position of the zygomatic, a very strong mandibular torus and, especially, a very reduced maxillary sinus. These are features shared with kenyapithecines believed to have dispersed outside the African continent and colonized the Mediterranean region, by about 15 million years ago.

In other words, the researchers speculate, hominids might have originally radiated in Eurasia from kenyapithecine ancestors of African origin. Later on, the ancestors of African great apes and humans would have dispersed again into Africa — the so-called “into Africa” theory, which remains controversial. However, the authors do not completely rule out the possibility that pongines (orangutans and related forms) and hominines (African apes and humans) separately evolved in Eurasia and Africa, respectively, from different kenyapithecine ancestors.

The project at els Hostalets de Pierola is continuing and, the researchers anticipate, more fossil remains will be found in the future that will provide key information to test their hypotheses.

2009-06-02 – Sebariu, Sardegna: Un nuovo paleo-museo

Serbariu: dinosauri e ragni

Apre i battenti il museo dei fossili

 di Sandro Mantega

 

Ha trecento milioni di anni, è il fossile di un ragno, probabilmente il più vecchio d’Italia. Ma sono ancora più vecchie le rocce della vetrina accanto: risalgono a un miliardo di anni fa, quando le terre emerse, a parte il Sulcis, erano davvero poche. A proposito di mare, questo arrivava fino a Perdaxius (un paese dell’interno del Sulcis), quando la roccia intrappolò le spugne di 530 milioni di anni. E c’è anche spazio alla spettacolarità: un calco del fossile di un Tirannosauro in grandezza naturale (otto metri) a dominare una delle grandi sale del capannone dove un tempo lavoravano gli operai della miniera. Sono i gioielli esposti nel museo “Paleoambienti sulcitani Martel”, nel complesso della Grande miniera di Serbariu, alla periferia di Carbonia. Un museo eccezionale nel quale figurano pezzi rari e preziosissimi dal punto di vista scientifico, come la raccolta di fossili che raccontano la storia della Terra a incominciare dal Cambriano (con la comparsa dei primi vertebrati), per finire con il Quarternario, nell’era Olocene, quella attuale. Il Museo paleontologico è stato realizzato sfruttando un capannone sapientemente restaurato dove si trovavano le forge della miniera di carbone attorno alla quale è nata la città. Ma la sua inaugurazione rappresenta qualcosa di più dell’apertura di un semplice, seppur unico, museo. E’, infatti, un altro importante tassello nella realizzazione di un progetto che soltanto qualche anno fa appariva utopico: recuperare e trasformare una vecchia miniera abbandonata in un luogo nel quale non solo tramandare le tradizioni, la cultura e la memoria di una popolazione e di un territorio ma anche portare avanti un discorso di sviluppo legato alla ricerca e a quanto di più moderno e attuale possa esistere. Ebbene la Grande miniera di Serbariu rappresenta la realizzazione di questa utopia. Ci sono i musei per tramadare la memoria e la cultura (il Centro Italiano del carbone con le gallerie artificiali, ora il museo paleontologico insieme alle altre testimonianze dell’archeologia mineraria), c’è la ricerca con il Centro della Sotacarbo dove si sperimenta la trasformazione del carbone in idrogeno, il polo di Sardegna ricerche, il centro universitario. C’è la cultura con e grandi sale attrezzate dove si celebrano simposi e congressi e si dibatte. C’è, soprattutto, la dimostrazione che anche una vecchia miniera può tornare a vivere proiettando una comunità verso il futuro.
