Blick Mead
Blick Mead is a chalkland spring in Wiltshire, England, separated by the River Avon from the northwest edge of the town of Amesbury. It is close to an Iron Age hillfort known as Vespasian's Camp and about a mile east of the Stonehenge ancient monument. Evidence from archaeology excavation at the site since 2005, indicates that there was continuous human habitation from 10,000 BP (8,000 BCE) to 6,000 BP (4,000 BCE). 35,000 worked flints and 2400 animal bones, some cooked, mostly from aurochsen, have been found at the site. There is also the remains of a pit dwelling. A few finds have been used to radiocarbon date the time of settlement. It is thought that the site would have been an attractive place to camp or dwell, with a spring that never freezes over; the issuing water has a constant temperature of around . Oxygen isotope There are three known stable isotopes of oxygen (8O): , , and . Radioactive isotopes ranging from to have also been characterized, all short ...

Stonehenge, Avebury And Associated Sites
Stonehenge, Avebury and Associated Sites is a UNESCO World Heritage Site (WHS) in Wiltshire, England. The WHS covers two large areas of land separated by about , rather than a specific monument or building. The sites were inscribed as co-listings in 1986. Some large and well known monuments within the WHS are listed below, but the area also has an exceptionally high density of small-scale archaeological sites, particularly from the prehistoric period. More than 700 individual archaeological features have been identified. There are 160 separate Scheduled Monuments, covering 415 items or features. Stonehenge and associated monuments The Stonehenge area of the WHS is in south Wiltshire. It covers an area of 26 square km and is centred on the prehistoric monument of Stonehenge. Ownership is shared between English Heritage, the National Trust, the Ministry of Defence (United Kingdom), Ministry of Defence, the RSPB, Wiltshire County Council, Wiltshire Council, and private individua ...

Pit Dwelling
A pit-house (or ''pit house'', ''pithouse'') is a house built in the ground and used for shelter. Besides providing shelter from the most extreme of weather conditions, these structures may also be used to store food (just like a pantry, a larder, or a root cellar) and for cultural activities like the telling of stories, dancing, singing and celebrations. General dictionaries also describe a pit-house as a ''dugout'', and it has similarities to a ''half-dugout''. In archaeology, a pit-house is frequently called a ''sunken-featured building'' and occasionally (grub-)hut or ''grubhouse'', after the German name ''Grubenhaus'' They are found in numerous cultures around the world, including the people of the Southwestern United States, the ancestral Pueblo, the ancient Fremont and Mogollon cultures, the Cherokee, the Inuit, the people of the Plateau, and archaic residents of Wyoming (Smith 2003) in North America; Archaic residents of the Lake Titicaca Basin (Craig 2005) in South Am ...

Archaeological Sites In Wiltshire
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the advent o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mesolithic
The Mesolithic (Greek: μέσος, ''mesos'' 'middle' + λίθος, ''lithos'' 'stone') or Middle Stone Age is the Old World archaeological period between the Upper Paleolithic and the Neolithic. The term Epipaleolithic is often used synonymously, especially for outside northern Europe, and for the corresponding period in the Levant and Caucasus. The Mesolithic has different time spans in different parts of Eurasia. It refers to the final period of hunter-gatherer cultures in Europe and Western Asia, between the end of the Last Glacial Maximum and the Neolithic Revolution. In Europe it spans roughly 15,000 to 5,000 BP; in Southwest Asia (the Epipalaeolithic Near East) roughly 20,000 to 10,000 BP. The term is less used of areas farther east, and not at all beyond Eurasia and North Africa. The type of culture associated with the Mesolithic varies between areas, but it is associated with a decline in the group hunting of large animals in favour of a broader hunter-g ...

Hildenbrandia
''Hildenbrandia'' is a genus of thalloid red alga comprising about 26 species. The slow-growing, non-mineralized thalli take a crustose form. ''Hildenbrandia'' reproduces by means of conceptacles and produces tetraspores. Morphology ''Hildenbrandia'' cells are around 3–5 μm in diameter and the filaments are around 50–75 μm in height. The thallus comprises two layers: the hypothallus, which attaches to the rock, and the perithallus, a pseudoparenchymous layer comprising vertical filaments, which unlike coralline red algae is not further differentiated. Growth ''Hildenbrandia'' comprises orderly layers of vertical oblong cells with thick vegetative cell walls, occasionally connected by secondary pit connections with pit plugs in the septal pores. It grows at its margins, away from the centre, and is able to quickly repair any gaps arising by regenerating from a basal layer of cells. As plants become more mature, they become multi-layered and strong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Premolar
The premolars, also called premolar teeth, or bicuspids, are transitional teeth located between the canine and molar teeth. In humans, there are two premolars per quadrant in the permanent set of teeth, making eight premolars total in the mouth. They have at least two cusps. Premolars can be considered transitional teeth during chewing, or mastication. They have properties of both the canines, that lie anterior and molars that lie posterior, and so food can be transferred from the canines to the premolars and finally to the molars for grinding, instead of directly from the canines to the molars. Human anatomy The premolars in humans are the maxillary first premolar, maxillary second premolar, mandibular first premolar, and the mandibular second premolar. Premolar teeth by definition are permanent teeth distal to the canines, preceded by deciduous molars. Morphology There is always one large buccal cusp, especially so in the mandibular first premolar. The lower second ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canine Tooth
In mammalian oral anatomy, the canine teeth, also called cuspids, dog teeth, or (in the context of the upper jaw) fangs, eye teeth, vampire teeth, or vampire fangs, are the relatively long, pointed teeth. They can appear more flattened however, causing them to resemble incisors and leading them to be called ''incisiform''. They developed and are used primarily for firmly holding food in order to tear it apart, and occasionally as weapons. They are often the largest teeth in a mammal's mouth. Individuals of most species that develop them normally have four, two in the upper jaw and two in the lower, separated within each jaw by incisors; humans and dogs are examples. In most species, canines are the anterior-most teeth in the maxillary bone. The four canines in humans are the two maxillary canines and the two mandibular canines. Details There are generally four canine teeth: two in the upper (maxillary) and two in the lower (mandibular) arch. A canine is placed laterally to ...

Radiocarbon Date
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calcu ...

Aurochs
The aurochs (''Bos primigenius'') ( or ) is an extinct cattle species, considered to be the wild ancestor of modern domestic cattle. With a shoulder height of up to in bulls and in cows, it was one of the largest herbivores in the Holocene; it had massive elongated and broad horns that reached in length. The aurochs was part of the Pleistocene megafauna. It probably evolved in Asia and migrated west and north during warm interglacial periods. The oldest known aurochs fossils found in India and North Africa date to the Middle Pleistocene and in Europe to the Holstein interglacial. As indicated by fossil remains in Northern Europe, it reached Denmark and southern Sweden during the Holocene. The aurochs declined during the late Holocene due to habitat loss and hunting, and became extinct when the last individual died in 1627 in Jaktorów forest in Poland. The aurochs is depicted in Paleolithic cave paintings, Neolithic petroglyphs, Ancient Egyptian reliefs and Bronze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Heritage Site
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain " cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. A ...
