Spy-sur-l'Orneau
Spy Cave (french: Grotte de Spy) is located in Wallonia near Spy in the municipality of Jemeppe-sur-Sambre, Namur Province, Belgium above the left bank of the Orneau River. Classified as a premier Heritage site of the Walloon Region, the location ranks among the most significant paleolithic sites in Europe. The cave consists of numerous small chambers and corridors.Camille Daujeard, Grégory Abrams, Mietje Germonpré, Jeanne-Marie Le Pape, Alicia Wampach, Kevin Di Modica, Marie-Hélène Moncel "Neanderthal and animal karstic occupations from southern Belgium and south-eastern France: Regional or common features?", ''Quaternary International'' Available online 27 May 2016, doi:10.1016/j.quaint.2016.02.009/ref> Excavations Since the first amateur investigations during the late 19th century numerous amateur and professional archaeologists have carried out excavations and removed all sediment deposits of the cave.

Julien Fraipont
Julien Jean Joseph Fraipont (17 August 1857 – 22 March 1910) was a Belgian paleontologist who worked as a professor of zoology at the University of Liège and is best known for his descriptive work on Neanderthal man. His son Charles Fraipont also became a paleontologist. Fraipont was born in Liege where his father directed a bank. He went to study humanities at the University of Liege so as to be able to work at his father's bank but shifted to the natural sciences after listening to the zoology lectures of Edouard Van Beneden. In 1881 he became an assistant to Van Beneden and began to lecture in paleontology from 1884, taking the position of Gustave Dewalque. In 1886 he became a professor and served as a rector in 1909. His major work was in the anatomical examination of the Neanderthal fossils found along with Max Lohest and others in Spy cave in 1886. He also worked on the systematics of the protozoa, hydrozoa, cestodes and the Archiannelida. He also wrote a monograph on th ...

Cave Hyena
The cave hyena (''Crocuta crocuta spelaea''), also known as the Ice Age spotted hyena, was a paleosubspecies of spotted hyena which ranged from the Iberian Peninsula to eastern Siberia. It is one of the best known mammals of the Ice Age and is well represented in many European bone caves. The cave hyena was a highly specialised animal, with its progressive and regressive features being more developed than in its modern African relative. It preyed on large mammals (primarily wild horses, steppe bison and woolly rhinoceros), and was responsible for the accumulation of hundreds of large Pleistocene mammal bones in areas including horizontal caves, sinkholes, mud pits and muddy areas along rivers. The cause of the cave hyena's extinction is not fully understood, though it could have been due to a combination of factors, including climate change and competition with other predators. Description and paleoecology The main difference between the spotted hyena and the cave hyena lies in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammoth
A mammoth is any species of the extinct elephantid genus ''Mammuthus'', one of the many genera that make up the order of trunked mammals called proboscideans. The various species of mammoth were commonly equipped with long, curved tusks and, in northern species, a covering of long hair. They lived from the Pliocene epoch (from around 5 million years ago) into the Holocene at about 4,000 years ago, and various species existed in Africa, Europe, Asia, and North America. They were members of the family Elephantidae, which also contains the two genera of modern elephants and their ancestors. Mammoths are more closely related to living Asian elephants than African elephants. The oldest representative of ''Mammuthus'', the South African mammoth (''M. subplanifrons''), appeared around 5 million years ago during the early Pliocene in what is now southern and eastern Africa. Descendant species of these mammoths moved north and continued to propagate into numerous subsequent spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Goyet Caves
The Goyet Caves (french: Grottes de Goyet) are a series of connected caves located in Wallonia in a limestone cliff about 15 m (50 ft) above the river Samson near the village of Mozet in the Gesves municipality of the Namur province, Belgium. The site is a significant locality of regional Neanderthal and European early modern human occupation, as thousands of fossils and artifacts were discovered that are all attributed to a long and contiguous stratigraphic sequence from 120,000 years ago, the Middle Palaeolithic to less than 5.000 years ago, the late Neolithic. A robust sequence of sediments was identified during extensive excavations by geologist Edouard Dupont, who undertook the first probings as early as 1867. The site was added to the Belgian National Heritage register in 1976. Site Located just south of the ''Goyet Castle'' the caves are essentially long underground galleries, rich in speleothems and carved out of the limestone during millions of years by the waters of ...

Nuclear DNA
Nuclear DNA (nDNA), or nuclear deoxyribonucleic acid, is the DNA contained within each cell nucleus of a eukaryotic organism. It encodes for the majority of the genome in eukaryotes, with mitochondrial DNA and plastid DNA coding for the rest. It adheres to Mendelian inheritance, with information coming from two parents, one male and one female—rather than matrilineally (through the mother) as in mitochondrial DNA. Structure Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells. Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin. Each strand is a long polymer chain of repeating nucleotides. Each nucleotide is composed of a five-carbon sugar, a phosphate group, and an organic base. Nucleotides are distinguished by their bases: purines, large bases that include adenine and guanine; and pyr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bayesian Probability
Bayesian probability is an Probability interpretations, interpretation of the concept of probability, in which, instead of frequentist probability, frequency or propensity probability, propensity of some phenomenon, probability is interpreted as reasonable expectation representing a state of knowledge or as quantification of a personal belief. The Bayesian interpretation of probability can be seen as an extension of propositional logic that enables reasoning with Hypothesis, hypotheses; that is, with propositions whose truth value, truth or falsity is unknown. In the Bayesian view, a probability is assigned to a hypothesis, whereas under frequentist inference, a hypothesis is typically tested without being assigned a probability. Bayesian probability belongs to the category of evidential probabilities; to evaluate the probability of a hypothesis, the Bayesian probabilist specifies a prior probability. This, in turn, is then updated to a posterior probability in the light of new, re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Before Present
Before Present (BP) years, or "years before present", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale. The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must now account for. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation RCYBP stands for the explicit "radio carbon years before present". Usage The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy. This usage differs from t ...

Upper Paleolithic
The Upper Paleolithic (or Upper Palaeolithic) is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 12,000 years ago (the beginning of the Holocene), according to some theories coinciding with the appearance of behavioral modernity in early modern humans, until the advent of the Neolithic Revolution and agriculture. Anatomically modern humans (i.e. ''Homo sapiens'') are believed to have emerged in Africa around 300,000 years ago, it has been argued by some that their ways of life changed relatively little from that of archaic humans of the Middle Paleolithic, until about 50,000 years ago, when there was a marked increase in the diversity of Artefact (archaeology), artefacts found associated with modern human remains. This period coincides with the most common date assigned to early human migrations, expansion of modern humans from Africa throughout Asia and Eurasia, which contributed to the Neanderthal extinction, ex ...

Mousterian
The Mousterian (or Mode III) is an archaeological industry of stone tools, associated primarily with the Neanderthals in Europe, and to the earliest anatomically modern humans in North Africa and West Asia. The Mousterian largely defines the latter part of the Middle Paleolithic, the middle of the West Eurasian Old Stone Age. It lasted roughly from 160,000 to 40,000 BP. If its predecessor, known as Levallois or Levallois-Mousterian, is included, the range is extended to as early as 300,000–200,000 BP. The main following period is the Aurignacian (c. 43,000–28,000 BP) of ''Homo sapiens''. Naming The culture was named after the type site of Le Moustier, three superimposed rock shelters in the Dordogne region of France. Similar flintwork has been found all over unglaciated Europe and also the Near East and North Africa. Handaxes, racloirs, and points constitute the industry; sometimes a Levallois technique or another prepared-core technique was employed in m ...

Flint
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Flint was widely used historically to make stone tools and start fires. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.''The Flints from Portsdown Hill'' Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along s and |
