Gough's Cave
Gough's Cave ( ) is located in Cheddar Gorge on the Mendip Hills, in Cheddar, Somerset, England. The cave is deep and is long, and contains a variety of large chambers and rock formations. It contains the Cheddar Yeo, the largest underground river system in Britain. History The initial sections of the cave, previously known as Sand Hole, were accessible prior to the 19th century. Between 1892 and 1898 a retired sea captain, Richard Cox Gough, who lived in Lion House in Cheddar, found, excavated and opened to the public further areas of the cave, up to Diamond Chamber, which is the end of the show cave today. Electric lighting was installed in the show caves in 1899. – which also contains a detailed description of the cave. The cave is susceptible to flooding often lasting for up to 48 hours, however in the Great Flood of 1968 the flooding lasted for three days. The extensive flooded parts of the cave system were found and explored between 1985 and 1990. Human remains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stalagmite
A stalagmite (, ; from the Greek , from , "dropping, trickling") is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter, and amberat (crystallized urine of pack rats). The corresponding formation hanging down from the ceiling of a cave is a stalactite. Mnemonics have been developed for which word refers to which type of formation; one is that ''stalactite'' has a C for "ceiling", and ''stalagmite'' has a G for "ground", another is that, as with ants in the pants, the mites go up and the tights (tites) come down. Formation and type Limestone stalagmites The most common stalagmites are speleothems, which usually form in limestone caves. Stalagmite formation occurs only under certain pH conditions within the cavern. They form through deposition of calcium carbonate ...

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] |
Perforated Baton
Perforated baton, bâton de commandement or bâton percé are names given by archaeologists to a type of particular prehistoric artifact from Prehistoric Europe, whose function remains debated. The name ''bâtons de commandement'' ("batons of command") was the name first applied to the class of artifacts, but it makes an assumption of function, as a ceremonial object or insignia held by leaders. The name ''bâton percé'', meaning "pierced rod", or "perforated baton" (the term used by the British Museum) is a more recent term, and is descriptive of form rather than any presumed function. Many are decorated with carved or engraved animals, and the most usual explanation of their use is that they were used for straightening spears and arrows, and as spear-throwers. Description and function Bâtons percés are made from a length of antler with a round hole made in one end, and often have abstract or animal designs etched into them (such as horses). They have been found at Aurign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hohle Fels
The ''Hohle Fels'' () (also ''Hohlefels'', ''Hohler Fels'', German for "hollow rock") is a cave in the Swabian Jura of Germany that has yielded a number of important archaeological finds dating from the Upper Paleolithic. Artifacts found in the cave represent some of the earliest examples of prehistoric art and musical instruments ever discovered. The cave is just outside the town of Schelklingen in the state of Baden-Württemberg, near Ulm. Because of the outstanding archeological finds and their cultural significance, in 2017 the site became part of the UNESCO World Heritage Site Caves and Ice Age Art in the Swabian Jura. Discoveries The first excavation took place in 1870, yielding remnants of cave bears, reindeer, mammoths and horses as well as tools belonging to the Aurignacian culture of the Upper Paleolithic. Further excavations during 1958 to 1960, 1977, and 2002 yielded a number of spectacular finds, including several specimens of prehistoric sculpture such as an ivor ...

Brillenhöhle
The Brillenhöhle (german: Brillenhöhle, literally ''spectacles cave'') is a cave ruin, located west of Ulm on the Swabian Alb in south-western Germany, where archaeological excavations have documented human habitation since as early as 30,000 years ago. Excavated by Gustav Riek from 1955 to 1963, the cave's Upper Paleolithic layers contain a sequence of Aurignacian, Gravettian and Magdalenian artifacts. In 1956 the first human fossils were discovered within a fireplace in the center of the cave, a discovery which made important contributions to the foundational understanding of the Magdalenian culture of central Europe. Site Brillenhöhle is located in the Ach Valley, lying about above the Ach River below. The site derives its name from the two holes in the cave's ceiling, which together resemble a pair of spectacles. The cave is essentially a single room with a diameter of , an average height of and a length of . A small side cave of width and height, called ''Vespe ...

Magdalenian Culture
The Magdalenian cultures (also Madelenian; French: ''Magdalénien'') are later cultures of the Upper Paleolithic and Mesolithic in western Europe. They date from around 17,000 to 12,000 years ago. It is named after the type site of La Madeleine, a rock shelter located in the Vézère valley, commune of Tursac, in France's Dordogne department. Édouard Lartet and Henry Christy originally termed the period ''L'âge du renne'' (the Age of the Reindeer). They conducted the first systematic excavations of the type site, publishing in 1875. The Magdalenian epoch is associated with reindeer hunters, although Magdalenian sites contain extensive evidence for the hunting of red deer, horses, and other large mammals present in Europe toward the end of the last glacial period. The culture was geographically widespread, and later Magdalenian sites stretched from Portugal in the west to Poland in the east, and as far north as France, the Channel Islands, England, and Wales. It is the th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Skull Cup
A skull cup is a drinking vessel or eating bowl made from an inverted human calvaria that has been cut away from the rest of the skull. The use of a human skull as a drinking cup in ritual use or as a trophy is reported in numerous sources throughout history and among various peoples, and among Western cultures is most often associated with the historically nomadic cultures of the Eurasian Steppe. The oldest directly dated skull cup at 14,700 cal BP (12,750 BC) comes from Gough's Cave, Somerset, England. Skulls used as containers can be distinguished from plain skulls by exhibiting cut-marks from flesh removal and working to produce a regular lip. Asia The oldest record in the Chinese annals of the skull-cup tradition dates from the last years of the Spring and Autumn period, when the victors of the Battle of Jinyang in 453 BC made the skull of their enemy into a winecup. Later, the ''Records of the Grand Historian'' recorded the practice among the ancient Xiongnu of present ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Skull
The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible. In humans, these two parts are the neurocranium and the viscerocranium ( facial skeleton) that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localisation of the direction and distance of sounds. In some animals, such as horned ungulates (mammals with hooves), the skull also has a defensive function by providing the mount (on the front ...

Aurochs
The aurochs (''Bos primigenius'') ( or ) is an extinct cattle species, considered to be the wild ancestor of modern domestic cattle. With a shoulder height of up to in bulls and in cows, it was one of the largest herbivores in the Holocene; it had massive elongated and broad horns that reached in length. The aurochs was part of the Pleistocene megafauna. It probably evolved in Asia and migrated west and north during warm interglacial periods. The oldest known aurochs fossils found in India and North Africa date to the Middle Pleistocene and in Europe to the Holstein interglacial. As indicated by fossil remains in Northern Europe, it reached Denmark and southern Sweden during the Holocene. The aurochs declined during the late Holocene due to habitat loss and hunting, and became extinct when the last individual died in 1627 in Jaktorów forest in Poland. The aurochs is depicted in Paleolithic cave paintings, Neolithic petroglyphs, Ancient Egyptian reliefs and Bronze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
