Manuport
A manuport is a natural object that has been deliberately taken from its original environment and relocated without further modification. Typically moved by human hand, some manuports are the result of other hominins. Common manuports include stones, seashells and fossils, which has led archaeologists and anthropologists to conclude they must have been chosen for their beauty. This recognition of an object’s aesthetic character suggests that certain manuports represent some of the earliest examples of art. Etymology The earliest attestation of the word manuport is from English in 1966. The term is derived from the Latin words ''manus'', meaning ‘hand’, and ''portare'', meaning ‘carry’. Notable manuports Makapansgat cobble The Makapansgat cobble was first discovered in the 1920s during excavations at an archaeological site in the Makapan Valley, South Africa. Although noted for its striking resemblance to a human face and its likely association with australopithec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erfoud Manuport
The Erfoud manuport (300,000-200,000 BP) is a 70 mm long and 35 mm wide (at its widest point) fossilized fragment of a cuttlefish resembling naturalistic, life-size, non-erect human phallus. The fossil was found in 1984 by Lutz Fiedler of Marburg University, Germany, at an archaeological site near the towns of Erfoud and Rissani in eastern Morocco. It was located among a dense cluster of Late Acheulian stone tools. No evidence of carving or shaping have been detected. While cuttlefish fossils are not themselves rare in other parts of Morocco, they are not native to the region in which the Erfoud manuport was found. It has, therefore, been thought that this fossil was intentionally brought back to the camp due to its natural phallic resemblance, which makes it a candidate for being a manuport. However, no further research regarding this artifact has been done. See also *Makapansgat pebble The Makapansgat pebble or Makapansgat cobble (wikt:circa, ca. 3,000,000 Before Present, BP) ...

Makapansgat Pebble
The Makapansgat pebble or Makapansgat cobble (wikt:circa, ca. 3,000,000 Before Present, BP) is a pebble with natural chipping and wear patterns that make it look like a crude rendition of a human face, in fact at least two possible faces. Some scholars argue that it is the oldest known manuport. Description The Makapansgat pebble is a 260-gram, 8.3 cm long, 7 cm wide, and 3.8 cm thick, reddish-brown jasperite Cobble (geology), cobble. The pebble was found in 1925 in a dolomite cave in the Makapansgat, Makapan Valley north of Mokopane, South Africa by a local school teacher Wilfred Eitzman. Importantly, it was found at 4.8 km/3 miles from the nearest possible natural source (or 32 km/20 miles according to Dart). The site also contained bones of Australopithecus (later this attribution was widened to australopithecines or other early hominins). The pebble and all its markings are formed naturally by geological processes, no traces of artificial modification have been detected. Int ...

Homo
''Homo'' () is the genus that emerged in the (otherwise extinct) genus ''Australopithecus'' that encompasses the extant species ''Homo sapiens'' ( modern humans), plus several extinct species classified as either ancestral to or closely related to modern humans (depending on the species), most notably ''Homo erectus'' and ''Homo neanderthalensis''. The genus emerged with the appearance of '' Homo habilis'' just over 2 million years ago. ''Homo'', together with the genus '' Paranthropus'', is probably sister to ''Australopithecus africanus'', which itself had previously split from the lineage of '' Pan'', the chimpanzees. ''Homo erectus'' appeared about 2 million years ago and, in several early migrations, spread throughout Africa (where it is dubbed ''Homo ergaster'') and Eurasia. It was likely that the first human species lived in a hunter-gatherer society and was able to control fire. An adaptive and successful species, ''Homo erectus'' persisted for more than a million ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chert
Chert () is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a precipitation (chemistry), chemical precipitate or a diagenesis, diagenetic replacement, as in petrified wood. Chert is typically composed of the petrified remains of siliceous ooze, the biogenic sediment that covers large areas of the deep ocean floor, and which contains the silicon skeletal remains of diatoms, Dictyochales, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to Micropaleontology, microfossils, chert occasionally contains macrofossils. However, some chert is devoid of any fossils. Chert varies greatly in color (from white to black), but most often manifests as gray, brown, grayish brown and light green to rusty redW.L.

Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...

Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

Petrifaction
In geology, petrifaction or petrification () is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals. Petrified wood typifies this process, but all organisms, from bacteria to vertebrates, can become petrified (although harder, more durable matter such as bone, beaks, and shells survive the process better than softer remains such as muscle tissue, feathers, or skin). Petrifaction takes place through a combination of two similar processes: permineralization and replacement. These processes create replicas of the original specimen that are similar down to the microscopic level. Processes Permineralization One of the processes involved in petrifaction is permineralization. The fossils created through this process tend to contain a large amount of the original material of the specimen. This process occurs when groundwater containing dissolved minerals (most commonly ...

Orthoceras
''Orthoceras'' ("straight horn") is a genus of extinct nautiloid cephalopod restricted to Middle Ordovician-aged marine limestones of the Baltic States and Sweden. This genus is sometimes called ''Orthoceratites''. Note it is sometimes misspelled as ''Orthocera'', ''Orthocerus'' or ''Orthoceros'' . ''Orthoceras'' was formerly thought to have had a worldwide distribution due to the genus' use as a wastebasket taxon for numerous species of conical-shelled nautiloids throughout the Paleozoic and Triassic. Since this work was carried out and re cataloging of the genus, ''Orthoceras'' sensu stricto refers to ''O. regulare'', of Ordovician-aged Baltic Sea limestones of Sweden and neighboring areas. These are slender, elongate shells with the middle of the body chamber transversely constricted, and a subcentral orthochoanitic siphuncle. The surface is ornamented by a network of fine lirae . Many other very similar species are included under the genus '' Michelinoceras''. History of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phallus
A phallus is a penis (especially when erect), an object that resembles a penis, or a mimetic image of an erect penis. In art history a figure with an erect penis is described as ithyphallic. Any object that symbolically—or, more precisely, iconically—resembles a penis may also be referred to as a phallus; however, such objects are more often referred to as being phallic (as in "phallic symbol"). Such symbols often represent fertility and cultural implications that are associated with the male sexual organ, as well as the male orgasm. Etymology The term is a loanword from Latin ''phallus'', itself borrowed from Greek (''phallos''), which is ultimately a derivation from the Proto-Indo-European root *''bʰel''- "to inflate, swell". Compare with Old Norse (and modern Icelandic) ''boli'' "bull", Old English ''bulluc'' "bullock", Greek "whale".

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] |
Stone Tool
A stone tool is, in the most general sense, any tool made either partially or entirely out of stone. Although stone tool-dependent societies and cultures still exist today, most stone tools are associated with prehistoric (particularly Stone Age) cultures that have become extinct. Archaeologists often study such prehistoric societies, and refer to the study of stone tools as lithic analysis. Ethnoarchaeology has been a valuable research field in order to further the understanding and cultural implications of stone tool use and manufacture. Stone has been used to make a wide variety of different tools throughout history, including arrowheads, spearheads, hand axes, and querns. Stone tools may be made of either ground stone or knapped stone, the latter fashioned by a flintknapper. Knapped stone tools are made from cryptocrystalline materials such as chert or flint, radiolarite, chalcedony, obsidian, basalt, and quartzite via a process known as lithic reduction.
