Okladnikov Cave
Okladnikov Cave (russian: пещера Окладникова) is a paleoanthropology, paleoanthropological site located in the foothills of the Altai Mountains in Soloneshensky District, Altai Krai in southern Siberia, Russia. The cave faces south and is located on a Devonian karst escarpment, lying about above the left bank of the Sibiryachikha River valley below; the river itself is a tributary of the Anuy River. Okladnikov Cave is one of the most extensively studied Paleolithic sites in the Altai-Sayan region. A rich Mousterian stone industry, dating to between 33,000 and 44,000 years ago, was discovered, as well as several highly fragmented hominin fossils. Along with a few other Neanderthal sites in the Altai-Sayan region, Okladnikov Cave contains fossil evidence for the most easterly confirmed site with Neanderthal presence. Background The cave was originally named after a nearby village, Sibiryachikha, located away. The cave was renamed by Anatoly Derevyanko, Anatoly P ...

Scraper (archaeology)
In prehistoric archaeology, scrapers are unifacial tools thought to have been used for hideworking and woodworking. Many lithic analysts maintain that the only true scrapers are defined on the base of use-wear, and usually are those that were worked on the distal ends of blades—i.e., "end scrapers" (french: grattoir, link=no). Other scrapers include the so-called "side scrapers" or racloirs, which are made on the longest side of a flake, and notched scrapers, which have a cleft on either side that may have been used to attach them to something else. Scrapers are typically formed by chipping the end of a flake of stone in order to create one sharp side and to keep the rest of the sides dull to facilitate grasping it. Most scrapers are either circle or blade-like in shape. The working edges of scrapers tend to be convex, and many have trimmed and dulled lateral edges to facilitate hafting. One important variety of scraper is the thumbnail scraper, a scraper shaped much like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diaphysis
The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow. In diaphysis, primary ossification occurs. Ewing sarcoma tends to occur at the diaphysis.Physical Medicine and Rehabilitation Board Review, Cuccurullo Additional images Illu long bone.jpg File:EpiMetaDiaphyse.jpg, Long bone See also *Epiphysis *Metaphysis The metaphysis is the neck portion of a long bone between the epiphysis and the diaphysis.

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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panthera Spelaea
''Panthera spelaea'', also known as the Eurasian cave lion, European cave lion or steppe lion, is an extinct ''Panthera'' species that most likely evolved in Europe after the third Cromerian interglacial stage, less than 600,000 years ago. Phylogenetic analysis of fossil bone samples revealed that it was highly distinct and genetically isolated from the modern lion (''Panthera leo'') occurring in Africa and Asia. Analysis of morphological differences and mitochondrial data support the taxonomic recognition of ''Panthera spelaea'' as a distinct species that genetically diverged from the lion about . Nuclear genomic evidence shows a more recent split approximately 500,000 years ago, with no subsequent interbreeding with the ancestors of the modern lion. The oldest known bone fragments were excavated in Yakutia and radiocarbon dated at least 62,400 years old. It became extinct about 13,000 years ago. Taxonomy ''Felis spelaea'' was the scientific name used by Georg August Goldfu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argali
The argali (''Ovis ammon''), also known as the mountain sheep, is a wild sheep that roams the highlands of western East Asia, the Himalayas, Tibet, and the Altai Mountains. Description The name 'argali' is the Mongolian word for wild sheep. It is the largest species of wild sheep. Argali stand high at the shoulder and measure long from the head to the base of the tail. The female, or ewe is the smaller sex by a considerable margin, sometimes weighing less than half as much as the male, or ram. The ewes can weigh from and the rams typically from , with a maximum reported mass of . The Pamir argali (also called Marco Polo sheep, for they were first described by that traveler), ''O. a. polii'', is the largest race on average, regularly measuring more than long without the tail, and is less sexually dimorphic in body mass than most other subspecies. The argali has relatively the shortest tail of any wild goat-antelope or sheep, with reported tail lengths of . The general colo ...

Siberian Ibex
The Siberian ibex (''Capra sibirica''), also known as the Altai ibex, Central Asia(n) ibex, Gobi ibex, Himalayan ibex, Mongolian ibex or Tian Shan ibex, is a species of ibex that lives in central Asia. It has traditionally been treated as a subspecies of the Alpine ibex, and whether it is specifically distinct from other ibex is still not entirely clear. It is the longest and heaviest member of the genus ''Capra'', though its shoulder height is surpassed by the markhor. Appearance Siberian ibexes are large and heavily built goats, although individual sizes vary greatly. Males are between in shoulder height, and weigh between . Females are noticeably smaller, with heights between , and weights between . The nose is straight in profile, the neck short, and the back straight. The neck is also particularly thick and muscular in males, but much less so in females. Both sexes have beards, although the male's beard is more pronounced, and those of females are sometimes absent altogeth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Woolly Rhinoceros
The woolly rhinoceros (''Coelodonta antiquitatis'') is an extinct species of rhinoceros that was common throughout Europe and Asia during the Pleistocene epoch and survived until the end of the last glacial period. The woolly rhinoceros was a member of the Pleistocene megafauna. The woolly rhinoceros was covered with long, thick hair that allowed it to survive in the extremely cold, harsh mammoth steppe. It had a massive hump reaching from its shoulder and fed mainly on herbaceous plants that grew in the steppe. Mummified carcasses preserved in permafrost and many bone remains of woolly rhinoceroses have been found. Images of woolly rhinoceroses are found among cave paintings in Europe and Asia. Taxonomy Woolly rhinoceros remains have been known long before the species was described, and were the basis for some mythical creatures. Native peoples of Siberia believed their horns were the claws of giant birds. A rhinoceros skull was found in Kl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave Hyena
The cave hyena (''Crocuta crocuta spelaea''), also known as the Ice Age spotted hyena, was a paleosubspecies of spotted hyena which ranged from the Iberian Peninsula to eastern Siberia. It is one of the best known mammals of the Ice Age and is well represented in many European bone caves. The cave hyena was a highly specialised animal, with its progressive and regressive features being more developed than in its modern African relative. It preyed on large mammals (primarily wild horses, steppe bison and woolly rhinoceros), and was responsible for the accumulation of hundreds of large Pleistocene mammal bones in areas including horizontal caves, sinkholes, mud pits and muddy areas along rivers. The cause of the cave hyena's extinction is not fully understood, though it could have been due to a combination of factors, including climate change and competition with other predators. Description and paleoecology The main difference between the spotted hyena and the cave hyena lies in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
