Handaxe
A hand axe (or handaxe or Acheulean hand axe) is a prehistoric stone tool with two faces that is the longest-used tool in human history, yet there is no academic consensus on what they were used for. It is made from stone, usually flint or chert that has been "reduced" and shaped from a larger piece by knapping, or hitting against another stone. They are characteristic of the lower Acheulean and middle Palaeolithic (Mousterian) periods, roughly 1.6 million years ago to about 100,000 years ago, and used by ''Homo erectus'' and other early humans, but rarely by ''Homo sapiens''. Their technical name (biface) comes from the fact that the archetypical model is a generally bifacial (with two wide sides or faces) and almond-shaped (amygdaloidal) lithic flake. Hand axes tend to be symmetrical along their longitudinal axis and formed by pressure or percussion. The most common hand axes have a pointed end and rounded base, which gives them their characteristic almond shape, and both ...

Acheulean
Acheulean (; also Acheulian and Mode II), from the French ''acheuléen'' after the type site of Saint-Acheul, is an archaeological industry of stone tool manufacture characterized by the distinctive oval and pear-shaped "hand axes" associated with '' Homo erectus'' and derived species such as ''Homo heidelbergensis''. Acheulean tools were produced during the Lower Palaeolithic era across Africa and much of West Asia, South Asia, East Asia and Europe, and are typically found with '' Homo erectus'' remains. It is thought that Acheulean technologies first developed about 1.76 million years ago, derived from the more primitive Oldowan technology associated with '' Homo habilis''. The Acheulean includes at least the early part of the Middle Paleolithic. Its end is not well defined, depending on whether Sangoan (also known as "Epi-Acheulean") is included, it may be taken to last until as late as 130,000 years ago. In Europe and Western Asia, early Neanderthals adopted Acheule ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Frere
John Frere (10 August 1740 – 12 July 1807) was an English antiquary and a pioneering discoverer of Old Stone Age or Lower Palaeolithic tools in association with large extinct animals at Hoxne, Suffolk in 1797. Life Frere was born in Roydon Hall, Norfolk, the son of Sheppard Frere and Susanna Hatley. Ellenor Fenn was his sister. In 1766, Frere received his MA from Gonville and Caius College, Cambridge, where he was Second Wrangler and was elected to a fellowship. He subsequently held several political offices and was appointed High Sheriff of Suffolk for 1776–77. He was elected a member of parliament for Norwich from 1799 to 1802. Antiquary An interest in the past, instigated by observing worked stone tools in a clay mining pit, led him to become a Fellow of the Society of Antiquaries of London and the Royal Society and to conduct excavations at a site just south of Hoxne, 8 km east, and across the River Waveney, from his home in Roydon, near Diss.

Homo Erectus
''Homo erectus'' (; meaning "upright man") is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago. Several human species, such as '' H. heidelbergensis'' and '' H. antecessor'' — with the former generally considered to have been the ancestor to Neanderthals, Denisovans, and modern humans — appear to have evolved from ''H. erectus''. Its specimens are among the first recognizable members of the genus ''Homo''. ''H. erectus'' was the first human ancestor to spread throughout Eurasia, with a continental range extending from the Iberian Peninsula to Java. Asian populations of ''H. erectus'' may be ancestral to '' H. floresiensis'' and possibly to '' H. luzonensis''. The last known population of ''H. erectus'' is '' H. e. soloensis'' from Java, around 117,000–108,000 years ago. ''H. erectus'' had a more modern gait and body proportions, and was the first human species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 emplo ...

Thunderstone (folklore)
A thunderstone is a prehistoric hand axe, stone tool, or fossil which was used as an amulet to protect a person or a building. The name derives from the ancient belief that the object was found at a place where lightning had struck. Thunderstone folklore European tradition Albanians believed in the supreme powers of thunder-stones (''kokrra e rrufesë'' or ''guri i rejës''), which were believed to be formed during lightning strikes and to be fallen from the sky. Thunder-stones were preserved in family life as important cult objects. It was believed that bringing them inside the house could bring good fortune, prosperity and progress in people, in livestock and in agriculture, or that rifle bullets would not hit the owners of the thunder-stones. A common practice was to hang a thunder-stone pendant on the body of the cattle or on the pregnant woman for good luck and to contrast the evil eye.

Lightning Strike
A lightning strike or lightning bolt is an electric discharge between the atmosphere and the ground. Most originate in a cumulonimbus cloud and terminate on the ground, called cloud-to-ground (CG) lightning. A less common type of strike, ground-to-cloud (GC) lightning, is upward-propagating lightning initiated from a tall grounded object and reaching into the clouds. About 25% of all lightning events worldwide are strikes between the atmosphere and earth-bound objects. Most are intracloud (IC) lightning and cloud-to-cloud (CC), where discharges only occur high in the atmosphere. Lightning strikes the average commercial aircraft at least once a year, but modern engineering and design means this is rarely a problem. The movement of aircraft through clouds can even cause lightning strikes. A single lightning event is a "flash", which is a complex, multistage process, some parts of which are not fully understood. Most CG flashes only "strike" one physical location, referred to as a " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amulet
An amulet, also known as a good luck charm or phylactery, is an object believed to confer protection upon its possessor. The word "amulet" comes from the Latin word amuletum, which Pliny's ''Natural History'' describes as "an object that protects a person from trouble". Anything can function as an amulet; items commonly so used include statues, coins, drawings, plant parts, animal parts, and written words. Amulets which are said to derive their extraordinary properties and powers from magic or those which impart luck are typically part of folk religion or paganism, whereas amulets or sacred objects of formalised mainstream religion as in Christianity are believed to have no power of their own without faith in Jesus and being blessed by a clergyman, and they supposedly will also not provide any preternatural benefit to the bearer who does not have an appropriate disposition. Talisman and amulets have interchangeable meaning. Amulets refer to any object which has the power to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knapping
Knapping is the shaping of flint, chert, obsidian, or other conchoidal fracturing stone through the process of lithic reduction to manufacture stone tools, strikers for flintlock firearms, or to produce flat-faced stones for building or facing walls, and flushwork decoration. The original Germanic term ''knopp'' meant to strike, shape, or work, so it could theoretically have referred equally well to making statues or dice. Modern usage is more specific, referring almost exclusively to the hand-tool pressure-flaking process pictured. It is distinguished from the more general verb "chip" (to break up into small pieces, or unintentionally break off a piece of something) and is different from "carve" (removing only part of a face), and "cleave" (breaking along a natural plane). Method Flintknapping or knapping is done in a variety of ways depending on the purpose of the final product. For stone tools and flintlock strikers, chert is worked using a fabricator such as a hammerston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuber
Tubers are a type of enlarged structure used as storage organs for nutrients in some plants. They are used for the plant's perennation (survival of the winter or dry months), to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction. ''Stem tubers'' form thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); well known species with stem tubers include the potato and yam. Some writers also treat modified lateral roots (''root tubers'') under the definition; these are found in sweet potatoes, cassava, and dahlias. Terminology The term originates from the Latin , meaning "lump, bump, swelling". Some writers define the term "tuber" to mean only structures derived from stems; others use the term for structures derived from stems or roots., p. 124 Stem tubers A stem tuber forms from thickened rhizomes or stolons. The top sides of the tuber produce shoots that grow into typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flake Tool
In archaeology, a flake tool is a type of stone tool that was used during the Stone Age that was created by striking a flake from a prepared stone core. People during prehistoric times often preferred these flake tools as compared to other tools because these tools were often easily made, could be made to be extremely sharp & could easily be repaired. Flake tools could be sharpened by retouch to create scrapers or burins. These tools were either made by flaking off small particles of flint or by breaking off a large piece and using that as a tool itself. These tools were able to be made by this "chipping" away effect due to the natural characteristic of stone. Stone is able to break apart when struck near the edge. Flake tools are created through flint knapping, a process of producing stone tools using lithic reduction. Lithic reduction Lithic reduction is the removal of a lithic flake from a larger stone in order to reach the desired tool shape and size. The beginning sto ...
