Clactonian Man
The Clactonian is the name given by archaeologists to an industry of European flint tool manufacture that dates to the early part of the interglacial period known as the Hoxnian, the Mindel-Riss or the Holstein stages (c. 400,000 years ago). Clactonian tools were made by ''Homo heidelbergensis''. It is named after 400,000-year-old finds made by Hazzledine Warren in a palaeochannel at Clacton-on-Sea in the English county of Essex in 1911. The artifacts found there included flint chopping tools, flint flakes and the tip of a worked wooden shaft along with the remains of a giant elephant and hippopotamus. Further examples of the tools have been found at sites including Barnfield Pit and Rickson's Pit, near Swanscombe in Kent and Barnham in Suffolk; similar industries have been identified across Northern Europe. The Clactonian industry involved striking thick, irregular flakes from a core of flint, which was then employed as a chopper. The flakes would have been used as crude kniv ...

Lower Paleolithic
The Lower Paleolithic (or Lower Palaeolithic) is the earliest subdivision of the Paleolithic or Old Stone Age. It spans the time from around 3 million years ago when the first evidence for stone tool production and use by hominins appears in the current archaeological record, until around 300,000 years ago, spanning the Oldowan ("mode 1") and Acheulean ("mode 2") lithics industries. In African archaeology, the time period roughly corresponds to the Early Stone Age, the earliest finds dating back to 3.3 million years ago, with Lomekwian stone tool technology, spanning Mode 1 stone tool technology, which begins roughly 2.6 million years ago and ends between 400,000 and 250,000 years ago, with Mode 2 technology. The Middle Paleolithic followed the Lower Paleolithic and recorded the appearance of the more advanced prepared-core tool-making technologies such as the Mousterian. Whether the earliest control of fire by hominins dates to the Lower or to the Middle Paleolithic remai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Essex
Essex () is a county in the East of England. One of the home counties, it borders Suffolk and Cambridgeshire to the north, the North Sea to the east, Hertfordshire to the west, Kent across the estuary of the River Thames to the south, and Greater London to the south and south-west. There are three cities in Essex: Southend, Colchester and Chelmsford, in order of population. For the purposes of government statistics, Essex is placed in the East of England region. There are four definitions of the extent of Essex, the widest being the ancient county. Next, the largest is the former postal county, followed by the ceremonial county, with the smallest being the administrative county—the area administered by the County Council, which excludes the two unitary authorities of Thurrock and Southend-on-Sea. The ceremonial county occupies the eastern part of what was, during the Early Middle Ages, the Anglo-Saxon Kingdom of Essex. As well as rural areas and urban areas, it forms ...

Bulb Of Percussion
In lithic analysis, a subdivision of archaeology, a bulb of applied force (also known as a bulb of percussion or simply bulb of force) is a defining characteristic of a lithic flake. Bulb of applied force was first correctly described by Sir John Evans, the cofounder of prehistoric archeology. However, bulb of percussion was coined scientifically by W.J. Sollas. When a flake is detached from its parent core, a portion of the Hertzian cone of force caused by the detachment blow is detached with it, leaving a distinctive bulb on the flake and a corresponding flake scar on the core. In the case of a unidirectional core, the bulb of applied force is produced by an initiated crack formed at the point of contact, which begins producing the Hertzian cone. The outward pressure increases causing the crack to curve away from the core and the bulb formation. The bulb of applied force forms below the striking platform as a slight bulge. If the flake is completely crushed the bulb will not be vis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retouch (lithics)
Retouch is the act of producing scars on a stone flake after the ventral surface has been created. It can be done to the edge of an implement in order to make it into a functional tool, or to reshape a used tool. Retouch can be a strategy to reuse an existing lithic artifact and enable people to transform one tool into another tool. Depending on the form of classification that one uses, it may be argued that retouch can also be conducted on a core-tool, if such a category exists, such as a hand-axe. Retouch may simply consist of roughly trimming an edge by striking with a hammerstone, or on smaller, finer flake or blade tools it is sometimes carried out by pressure flaking. Other forms of retouch may include burination, which is retouch that is conducted in a parallel orientation to the flake margin. Retouch is often taken as one of the most obvious features distinguishing a tool from a waste by-product of lithic manufacture (debitage In archaeology, debitage is all the material ...

Oldowan
The Oldowan (or Mode I) was a widespread stone tool archaeological industry (style) in prehistory. These early tools were simple, usually made with one or a few flakes chipped off with another stone. Oldowan tools were used during the Lower Paleolithic period, 2.6 million years ago up until at least 1.7 million years ago, by ancient Hominins (early humans) across much of Africa. This technological industry was followed by the more sophisticated Acheulean industry (two sites associated with ''Homo erectus'' at Gona in the Afar Region of Ethiopia dating from 1.5 and 1.26 million years ago have both Oldowan and Acheulean tools). The term ''Oldowan'' is taken from the site of Olduvai Gorge in Tanzania, where the first Oldowan stone tools were discovered by the archaeologist Louis Leakey in the 1930s. However, some contemporary archaeologists and palaeoanthropologists prefer to use the term ''Mode 1'' tools to designate pebble tool industries (including Oldowan), with ''Mode 2'' ...

Chopper (archaeology)
Archaeologists define a chopper as a pebble tool with an irregular cutting edge formed through the removal of flakes from one side of a stone. Choppers are crude forms of stone tool and are found in industries as early as the Lower Palaeolithic from around 2.5 million years ago. These earliest known specimens were found in the Olduvai Gorge in Tanzania by Louis Leakey in the 1930s. The name Oldowan was given to the tools after the site in which they were excavated. These types of tools were used an estimated time range of 2.5 to 1.2 million years ago. Formation To create this tool, one would have to use a hammerstone to chip away flakes on the stone to create a side of the stone with a very sharp edge, allowing for the cutting and hacking of an object. This is a unique type of lithic reduction, as only a single side of the stone is retouched to produce the cutting surface of the stone. The side that does not do the cutting is left unscathed, an unusual practice. These old ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Europe
The northern region of Europe has several definitions. A restrictive definition may describe Northern Europe as being roughly north of the southern coast of the Baltic Sea, which is about 54th parallel north, 54°N, or may be based on other geographical factors such as climate and ecology. Climate The climate is mainly Oceanic climate (Cfb), Humid continental climate (Dfb), Subarctic climate (Dfc and Dsc) and Tundra (ET). Geography Northern Europe might be defined roughly to include some or all of the following areas: British Isles, Fennoscandia, the peninsula of Jutland, the Baltic region, Baltic plain that lies to the east and the many islands that lie offshore from mainland Northern Europe and the main European continent. In some cases, Greenland is also included, although it is only politically European, comprising part of the Kingdom of Denmark, and not considered to be geographically in Europe. The area is partly mountainous, including the northern volcanic islands ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suffolk
Suffolk () is a ceremonial county of England in East Anglia. It borders Norfolk to the north, Cambridgeshire to the west and Essex to the south; the North Sea lies to the east. The county town is Ipswich; other important towns include Lowestoft, Bury St Edmunds, Newmarket, and Felixstowe which has one of the largest container ports in Europe. The county is low-lying but can be quite hilly, especially towards the west. It is also known for its extensive farming and has largely arable land with the wetlands of the Broads in the north. The Suffolk Coast & Heaths and Dedham Vale are both nationally designated Areas of Outstanding Natural Beauty. History Administration The Anglo-Saxon settlement of Suffolk, and East Anglia generally, occurred on a large scale, possibly following a period of depopulation by the previous inhabitants, the Romanised descendants of the Iceni. By the fifth century, they had established control of the region. The Anglo-Saxon inhabitants later b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kent
Kent is a county in South East England and one of the home counties. It borders Greater London to the north-west, Surrey to the west and East Sussex to the south-west, and Essex to the north across the estuary of the River Thames; it faces the French department of Pas-de-Calais across the Strait of Dover. The county town is Maidstone. It is the fifth most populous county in England, the most populous non-Metropolitan county and the most populous of the home counties. Kent was one of the first British territories to be settled by Germanic tribes, most notably the Jutes, following the withdrawal of the Romans. Canterbury Cathedral in Kent, the oldest cathedral in England, has been the seat of the Archbishops of Canterbury since the conversion of England to Christianity that began in the 6th century with Saint Augustine. Rochester Cathedral in Medway is England's second-oldest cathedral. Located between London and the Strait of Dover, which separates England from mainla ...

Swanscombe
Swanscombe Help:IPA/English, /ˈswɒnzkəm/ is a village in the Borough of Dartford in Kent, England, and the civil parish of Swanscombe and Greenhithe. It is 4.4 miles west of Gravesend and 4.8 miles east of Dartford. History Prehistory Bone fragments and tools, representing the earliest humans known to have lived in England, have been found from 1935 onwards at the ''Barnfield Pit'' about outside the village. This site is now the Swanscombe Heritage Park. Swanscombe Man (now thought to be female) was a late ''Homo erectus'' or an early Archaic humans, Archaic ''Homo sapiens''. According to the Natural History Museum, London, Natural History Museum, however, the remains are those of a 400,000-year-old early Neanderthal woman. The c. 400,000-year-old skull fragments are kept at the Natural History Museum, London, Natural History Museum in London with a replica on display at the Dartford Museum. Lower levels of the Barnfield Pit yielded evidence of an even earlier, more pri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barnfield Pit
Swanscombe Skull Site or Swanscombe Heritage Park is a geological Site of Special Scientific Interest in Swanscombe in north-west Kent, England. It contains two Geological Conservation Review sites and a National Nature Reserve. The park lies in a former gravel quarry, Barnfield Pit. The area was already known for the finds of numerous Palaeolithic-era handaxes—mostly Acheulean and Clactonian artifacts, some as much as 400,000 years old—when in 1935/1936 work at Barnfield Pit uncovered two fossilised skull fragments. These fragments came to be known as the remains of Swanscombe Man but were later found to have belonged to a young woman. The Swanscombe skull has been identified as early Neanderthal or pre-Neanderthal, dating to the Hoxnian Interglacial around 400,000 years ago. The skull fragments were found in the lower middle terrace gravels at a depth of almost 8 metres. They were found by Alvan T. Marston, an amateur archaeologist who visited the pit betwee ...

Hippopotamus Antiquus
''Hippopotamus antiquus'', sometimes called the European hippopotamus, is an extinct species of ''Hippopotamus'' that ranged across Europe during the Early and Middle Pleistocene. Chronology In Italy, the first appearance of the taxon is during the late Early Pleistocene, around 1.2 Ma, remains from Coste San Giacomo, suggested to date to around 2 Ma, have an uncertain stratigraphic context. ''H. antiquus'' first became widespread north of the Alps around 1.1 to 1 million years ago. The youngest confirmed remains of the taxon date to MIS 15, (621–563,000 years ago), but there are possibly later records dating to MIS 11 (424,000 to 374,000 years ago). Later records of ''Hippopotamus'' in continental Europe beginning in MIS 13 (~524,000-474,000 years ago), are believed to belong to the modern hippopotamus (''Hippopotamus amphibius''). Biology ''H. antiquus'' ranged from the Iberian Peninsula to the British Isles to the Rhine River to Greece."150 Years of Neanderthal Discover ...
