Pettakere Cave
The caves in the Maros-Pangkep karst are situated in South Sulawesi, Indonesia, and contain paintings from the Paleolithic considered to be the earliest figurative art in the world, dated to at least 43,900 years ago. Description The caves in the Maros-Pangkep karst are a cave complex, where prehistoric finds were made. The whole complex is also called "Prehistoric place Leang-Leang" – the name stems from the Makassarese language. The various caves - named Pettae, Jane, Saripa, Jarie, Karrasa, and so on - consist of limestone. They are located from the town of Maros and from the city of Makassar. The entrance to the caves is located above a rice field, accessible by ladder. A hand stencil in the Leang Tempuseng cave was dated to at least 39,900 years old in a 2014 study. The depiction of a babirusa is also located in this cave. It is estimated to be 35,400 years old. The art works were examined with the help of the Uranium-Thorium method of the sintering on the painti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hands In Pettakere Cave
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the koala (which has two opposable thumbs on each "hand" and fingerprints extremely similar to human fingerprints) are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking. Some evolutionary anatomists use the term ''hand'' to refer to the appendage of digits on the forelimb more generally—for example, in the context of whether the three digits of the bird hand involved the same homologous loss of two digits as in the dinosaur hand. The human hand usually has five digits: four fingers plus one thumb; these are often referred to collectively as five fingers, however, whereby the thumb is included as one of the fingers. It has 27 bones, not including the sesamoid bone, the number of whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Isotopes Of Uranium
Uranium (92U) is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust. The decay product uranium-234 is also found. Other isotopes such as uranium-233 have been produced in breeder reactors. In addition to isotopes found in nature or nuclear reactors, many isotopes with far shorter half-lives have been produced, ranging from 214U to 242U (with the exceptions of 220U and 241U). The standard atomic weight of natural uranium is . Naturally occurring uranium is composed of three major isotopes, uranium-238 (99.2739–99.2752% natural abundance), uranium-235 (0.7198–0.7202%), and uranium-234 (0.0050–0.0059%). All three isotopes are radioactive (i.e., they are radioisotopes), and the most abundant and stable is uranium-238, with a half-life of (close to the age of the Earth). Uranium-238 is an alpha emitter, decayi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Guardian
''The Guardian'' is a British daily newspaper. It was founded in 1821 as ''The Manchester Guardian'', and changed its name in 1959. Along with its sister papers ''The Observer'' and ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators.

Celebes Warty Pig
The Celebes warty pig (''Sus celebensis''), also called Sulawesi warty pig or Sulawesi pig, is a species in the pig genus ('' Sus'') that lives on Sulawesi in Indonesia. It survives in most habitats and can live in altitudes of up to . It has been domesticated and introduced to a number of other islands in Indonesia. Description The Celebes warty pig is a medium-sized pig, and quite variable in size and appearance. Although a number of subspecies have been recognised, it is now regarded as a monotypic taxon. It is the only pig species that has been domesticated apart from the wild boar; being semi-domesticated may have had an influence on the variability of its appearance. This pig has a head-and-body length of between and a long tail, with males generally being larger than females. The back is rounded and the legs short. The colour is greyish-black, sometimes tinged with red or yellow on the flanks. There are three pairs of facial warts and a fringe of pale bristles on the snout ...

Speleothem
A speleothem (; ) is a geological formation by mineral deposits that accumulate over time in natural caves. Speleothems most commonly form in calcareous caves due to carbonate dissolution reactions. They can take a variety of forms, depending on their depositional history and environment. Their chemical composition, gradual growth, and preservation in caves make them useful paleoclimatic proxies. Chemical and physical characteristics More than 300 variations of cave mineral deposits have been identified. The vast majority of speleothems are calcareous, composed of calcium carbonate (CaCO3) minerals (calcite or aragonite). Less commonly, speleothems are made of calcium sulfate (gypsum or mirabilite) or opal. Speleothems of pure calcium carbonate or calcium sulfate are translucent and colorless. The presence of iron oxide or copper provides a reddish brown color. The presence of manganese oxide can create darker colors such as black or dark brown. Speleothems can also be brown d ...

Anoa
Anoa, also known as dwarf buffalo and ''sapiutan'', are two species of the genus '' Bubalus'' endemic to the island of Sulawesi in Indonesia: the mountain anoa (''Bubalus quarlesi'') and the lowland anoa (''Bubalus depressicornis''). Both live in undisturbed rainforest and are similar in appearance to miniature water buffaloes, weighing . Both species of anoa have been classified as endangered since the 1960s and the populations continue to decrease. Fewer than 5,000 animals of each species likely remain. Reasons for their decline include hunting for hides, horns and meat by the local peoples and loss of habitat due to the advancement of settlement. Currently, hunting is the more serious factor in most areas. Anoa are most closely allied to the larger Asian buffaloes, showing the same reversal of the direction of the hair on their backs. The horns are peculiar for their upright direction and comparative straightness, although they have the same triangular section as in ot ...

Therianthropy
Therianthropy is the mythological ability of human beings to metamorphose into animals or hybrids by means of shapeshifting. It is possible that cave drawings found at Les Trois Frères, in France, depict ancient beliefs in the concept. The best-known form of therianthropy, called lycanthropy, is found in stories of werewolves. Etymology The term ''therianthropy'' comes from the Greek ''thēríon'' ηρίον meaning "wild animal" or "beast" (implicitly mammalian), and ''anthrōpos'' νθρωπος meaning "human being". It was used to refer to animal transformation folklore of Europe as early as 1901. Sometimes the term " zoanthropy" is used instead. Therianthropy was used to describe spiritual beliefs in animal transformation in a 1915 Japanese publication, ''A History of the Japanese People from the Earliest Times to the End of the Meiji Era''. One source, ''The Human Predator'', raises the possibility the term may have been used as early as the 16th century in crim ...

Hog Deer
''Axis'' is a genus of deer occurring in South and Southeast Asia. As presently defined by most authorities, four species are placed in the genus. Three of the four species are called hog deer. The genus name is a word mentioned in Pliny the Elder's Natural History. Species Following the third edition of ''Mammal Species of the World ''Mammal Species of the World: A Taxonomic and Geographic Reference'' is a standard reference work in mammalogy giving descriptions and bibliographic data for the known species of mammals. It is now in its third edition, published in late 2005, ...'' from 2005, which is also followed by the American Society of Mammalogists, four species are placed in ''Axis''. These four species are divided into two subgenera; ''Axis'' containing the chital, and ''Hyelaphus'' containing the 3 others.

Stencil
Stencilling produces an image or pattern on a surface, by applying pigment to a surface through an intermediate object, with designed holes in the intermediate object, to create a pattern or image on a surface, by allowing the pigment to reach only some parts of the surface. The stencil is both the resulting image or pattern and the intermediate object; the context in which ''stencil'' is used makes clear which meaning is intended. In practice, the (object) stencil is usually a thin sheet of material, such as paper, plastic, wood or metal, with letters or a design cut from it, used to produce the letters or design on an underlying surface by applying pigment through the cut-out holes in the material. The key advantage of a stencil is that it can be reused to repeatedly and rapidly produce the same letters or design. Although aerosol or painting stencils can be made for one-time use, typically they are made with the intention of being reused. To be reusable, they must remain int ...
