Azilian Painted Pebbles From The Cave Of Le Mas D'Azil
The Azilian is a Mesolithic industry of the Franco-Cantabrian region of northern Spain and Southern France. It dates approximately 10,000–12,500 years ago. Diagnostic artifacts from the culture include projectile points (microliths with rounded retouched backs), crude flat bone harpoons and pebbles with abstract decoration. The latter were first found in the River Arize at the type-site for the culture, the ''Grotte du Mas d'Azil'' at Le Mas-d'Azil in the French Pyrenees (illustrated, now with a modern road running through it). These are the main type of Azilian art, showing a great reduction in scale and complexity from the Magdalenian Art of the Upper Palaeolithic. The industry can be classified as part of the Epipaleolithic or the Mesolithic periods, or of both. Archaeologists think the Azilian represents the tail end of the Magdalenian as the warming climate brought about changes in human behaviour in the area. The effects of melting ice sheets would have diminished the fo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Western Europe
Western Europe is the western region of Europe. The region's countries and territories vary depending on context. The concept of "the West" appeared in Europe in juxtaposition to "the East" and originally applied to the ancient Mediterranean world, the Roman Empire (Western Roman Empire and Eastern Roman Empire), and medieval "Christendom" (Western Christianity and Eastern Christianity). Beginning with the Renaissance and the Age of Discovery, roughly from the 15th century, the concept of ''Europe'' as "the West" slowly became distinguished from and eventually replaced the dominant use of "Christendom" as the preferred endonym within the region. By the Age of Enlightenment and the Industrial Revolution, the concepts of "Eastern Europe" and "Western Europe" were more regularly used. Historical divisions Classical antiquity and medieval origins Prior to the Roman conquest, a large part of Western Europe had adopted the newly developed La Tène culture. As the Roman domain ...

Glacial Refugium
A glacial refugium (''plural refugia'') is a geographic region which made possible the survival of flora and fauna in times of ice ages and allowed for post-glacial re-colonization. Different types of glacial refugia can be distinguished, namely nunatak, peripheral and lowland refugia.Holderegger, R., Thiel-Egenter, C. (2009): A discussion of different types of glacial refugia used in mountain biogeography and phytogeography. Journal of Biogeography 36, 476-480. Glacial refugia have been suggested as a major cause of the patterns of distributions of flora and fauna in both temperate and tropical latitudes. With respect to disjunct populations of modern-day species distributions, especially in birds, doubt has been cast on the validity of such inferences, as much of the differentiation between populations observed today may have occurred before or after their restriction to refugia. In contrast, isolated geographic locales that host one or more critically endangered species (regarded ...

Pecten (bivalve)
''Pecten'' is a genus of large scallops or saltwater clams, marine bivalve molluscs in the family Pectinidae, the scallops. This is the type genus of the family. This genus is known in the fossil record from the Cretaceous period to the Quaternary period (age range: from 70.6 to 0.0 million years ago). Fossil shells within this genus have been found all over the world. Etymology The name ''Pecten'' is from the Latin word for a comb or rake. Since 1904, a ''Pecten'' shell has been used as the basis of the logo of Shell petroleum company. Species Species in the genus ''Pecten'' include: *'' P. albicans'' (Schröter, 1802) *'' P. afribenedictus'' Kilburn & Dijkstra 1995 *'' P. alcesianus'' † McLearn 1933 *'' P. alpha'' † Dall 1898 *'' P. argillensis'' † Conrad 1860 *'' P. assinboiensis'' † Russell & Landes 1937 *'' P. aurantiacus'' Roding 1798 *'' P. aztecus'' † Bose 1906 *'' P. barretti'' † Seeley 1861 *'' P. bifidus'' † Menke 1843 *'' P.biddleana'' †Kell ...

Iron Oxide
Iron oxides are chemical compounds composed of iron and oxygen. Several iron oxides are recognized. All are black magnetic solids. Often they are non-stoichiometric. Oxyhydroxides are a related class of compounds, perhaps the best known of which is rust. Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, catalysts, and in thermite, and occur in hemoglobin. Iron oxides are inexpensive and durable pigments in paints, coatings and colored concretes. Colors commonly available are in the "earthy" end of the yellow/orange/red/brown/black range. When used as a food coloring, it has E number E172. Stoichiometries Iron oxides feature as ferrous ( Fe(II)) or ferric ( Fe(III)) or both. They adopt octahedral or tetrahedral coordination geometry. Only a few oxides are significant at the earth's surface, particularly wüstite, magnetite, and hematite. * Oxides of FeII ...

Engraving
Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it with a Burin (engraving), burin. The result may be a decorated object in itself, as when silver, gold, steel, or Glass engraving, glass are engraved, or may provide an Intaglio (printmaking), intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engraving is a form of relief printing and is not covered in this article, same with rock engravings like petroglyphs. Engraving was a historically important method of producing images on paper in artistic printmaking, in mapmaking, and also for commercial reproductions and illustrations for books and magazines. It has long been replaced by various photographic processes in its commercial applications and, partly because of the difficulty of learning th ...

Vasco-Cantabria
Vasco-Cantabria, in archaeology and the environmental sciences, is an area on the northern coast of Spain. It covers similar areas to the northern parts of the adjacent modern regions of the Basque Country (greater region), Basque country and Cantabria. In geology the "Vasco-Cantabrian Basin" or "Basque-Cantabrian Basin" covers the area and the seas off the coast, in the Bay of Biscay, an area between the Iberian Plate, Iberian and European tectonic plates. The area is of special significance in the archaeology of the Upper Palaeolithic, Epipalaeolithic and Mesolithic periods of the Stone Age. A narrow coastal strip was a glacial refugium, never covered by glaciers during the Last Glacial Maximum, and appears to have been densely populated. It is part of the wider Franco-Cantabrian region (also ''Franco-Cantabric region'') that stretches from Asturias, the next region west of Cantabria, to Provence in southeastern France. The main archaeological industries in the area during thi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Oban
Oban ( ; ' in Scottish Gaelic meaning ''The Little Bay'') is a resort town within the Argyll and Bute council area of Scotland. Despite its small size, it is the largest town between Helensburgh and Fort William. During the tourist season, the town can have a temporary population of up to over 24,000 people. Oban occupies a setting in the Firth of Lorn. The bay forms a near perfect horseshoe, protected by the island of Kerrera; and beyond Kerrera, the Isle of Mull. To the north, is the long low island of Lismore and the mountains of Morvern and Ardgour. Pre-history and archaeology Humans have used the site where Oban now stands since at least Mesolithic times, as evidenced by archaeological remains of cave dwellers found in the town. Just outside the town, stands Dunollie Castle, on a site that overlooks the main entrance to the bay and has been fortified since the Bronze Age. Just to the north of Oban, at Dunstaffnage, excavations in 2010, by Argyll Archaeology, in advanc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hugo Obermaier
Hugo Obermaier (29 January 1877, in Regensburg – 12 November 1946, in Fribourg) was a distinguished Spanish-German prehistorian and anthropologist who taught at various European centres of learning. Although he was born in Germany, he was later naturalized as a Spanish citizen in 1924. He is particularly associated with his work on the diffusion of mankind in Europe during the Ice Age, and in connection with north Spanish cave art, and resisted placing his science at the disposal of nationalistic and racialist interests in the Germany of the 1930s.This article is translated from the German Wikipedia, August 2008. The principal source is the biography by the Hugo Obermaier Society for Palaolithic Research, indicated among the external links Career Hugo Obermaier spent his childhood and the early part of his student years in Regensburg. In 1900 he was ordained as a diocesan priest and between 1901 and 1904 he studied in Vienna the subjects of Prehistoric archaeology, physical geo ...
