Microblade technology is a period of technological microlith development marked by the creation and use of small stone blades, which are produced by chipping silica-rich stones like chert, quartz, or obsidian. Blades are a specialized type of lithic flake that are at least twice as long as they are wide. [1] An alternate method of defining blades focuses on production features, including parallel lateral edges and dorsal scars, a lack of cortex, a prepared platform with a broad angle, and a proximal bulb of percussion. [2] Microblades are generally less than 50 mm long in their finished state. [3]
The geographic origin of microblades is poorly understood, with differing theories posing origins in Southern Siberia, Northern China, or the PHSK (Paleo-Hokkaido-Sakhalin-Kurile) peninsula, with dates ranging from over 30,000 BP to as little as 18,000 BP. The microblade technology has been associated with the Ancient Paleo-Siberians. [4] Because microblade technology is economical (using less raw material than other technologies), relatively easy to make, and extremely portable, it came into widespread use over vast parts of northern Asia and northeastern Siberia during and after the Ice Age. Microblade technology was very efficient for hunting because it used light, barbed spears. During the Ice Age, hunter-gatherers suffered from shortage of food resources, so they had to move more frequently. Microblade is suitable for high mobility and rapid weapon production, as well as reducing failure of hunting and lost or damaged weapons. [5] In other words, in the resource-limited environment of the Last Glacial Maximum, hunter-gatherers invested more time acquiring better raw materials and developing the technique of lithic manufacture. [6] Barbed tips opened wounds and the resulting blood loss killed prey faster and with less loss of hunting equipment than traditional spears.
These changes in lithic technology appear to have been adaptations to reduced resource availability due to climate changes during the Last Glacial Maximum and Younger Dryas allowing for more efficient sustenance strategies. An important site for learning more about the diverse adaptations of the microblade is Shuidonggou Locality 12 (SDG12). It was at this site that microblades were found along with diverse artifacts: needles, awls, and a bone knife handle. This handle is a big indicator that microblades were used for multiple purposes, and no longer were exclusive to hunting. [7] In at least one site in Northern China, microblades are also found in context with heat shattered and burned stone, usually evidence for stone-boiling practices, another resource intensification strategy aimed at recovering more nutrients from food resources via cooking. [8]
The first Native Americans brought this technology with them across the Bering Land Bridge to North America. At least six independent Native American groups used microblade technology, including the Poverty Point/Jaketown, Hopewell culture, Tikal Maya, and Northwest Coast peoples. Specialized craftspeople manufactured millions of microblades in the Mississippian chiefdom of Cahokia, in Illinois, [9] as did Chumash (tribe) craftspeople in California's Northern Channel Islands. In both of these cases, microblades were sharpened to a point and attached to the end of sticks, creating microdrills. These microdrills were used to drill holes in marine shells to create beads. Shell beads were used as money among the Chumash, and as a result microblades were a vital part of the Chumash economy.
The Epipalaeolithic Near East designates the Epipalaeolithic in the prehistory of the Near East. It is the period after the Upper Palaeolithic and before the Neolithic, between approximately 20,000 and 10,000 years Before Present (BP). The people of the Epipalaeolithic were nomadic hunter-gatherers who generally lived in small, seasonal camps rather than permanent villages. They made sophisticated stone tools using microliths—small, finely-produced blades that were hafted in wooden implements. These are the primary artifacts by which archaeologists recognise and classify Epipalaeolithic sites.
The Mesolithic or Middle Stone Age is the Old World archaeological period between the Upper Paleolithic and the Neolithic. The term Epipaleolithic is often used synonymously, especially for outside northern Europe, and for the corresponding period in the Levant and Caucasus. The Mesolithic has different time spans in different parts of Eurasia. It refers to the final period of hunter-gatherer cultures in Europe and the Middle East, between the end of the Last Glacial Maximum and the Neolithic Revolution. In Europe it spans roughly 15,000 to 5,000 BP; in the Middle East roughly 20,000 to 10,000 BP. The term is less used of areas farther east, and not at all beyond Eurasia and North Africa.
In archaeology, the Epipalaeolithic or Epipaleolithic is a period occurring between the Upper Paleolithic and Neolithic during the Stone Age. Mesolithic also falls between these two periods, and the two are sometimes confused or used as synonyms. More often, they are distinct, referring to approximately the same period of time in different geographic areas. Epipaleolithic always includes this period in the Levant and, often, the rest of the Near East. It sometimes includes parts of Southeast Europe, where Mesolithic is much more commonly used. Mesolithic very rarely includes the Levant or the Near East; in Europe, Epipalaeolithic is used, though not very often, to refer to the early Mesolithic.
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 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.
A hunter-gatherer or forager is a human living in a community, or according to an ancestrally derived lifestyle, in which most or all food is obtained by foraging, that is, by gathering food from local naturally occurring sources, especially edible wild plants but also insects, fungi, honey, bird eggs, or anything safe to eat, and/or by hunting game. This is a common practice among most vertebrates that are omnivores. Hunter-gatherer societies stand in contrast to the more sedentary agricultural societies, which rely mainly on cultivating crops and raising domesticated animals for food production, although the boundaries between the two ways of living are not completely distinct.
Clovis points are the characteristically fluted projectile points associated with the New World Clovis culture, a prehistoric Paleo-American culture. They are present in dense concentrations across much of North America and they are largely restricted to the north of South America. There are slight differences in points found in the Eastern United States bringing them to sometimes be called "Clovis-like". Clovis points date to the Early Paleoindian period, with all known points dating from roughly 13,400–12,700 years ago. As an example, Clovis remains at the Murry Springs Site date to around 12,900 calendar years ago. Clovis fluted points are named after the city of Clovis, New Mexico, where examples were first found in 1929 by Ridgely Whiteman.
Dicerorhinus is a genus of the family Rhinocerotidae, consisting of a single extant species, the two-horned Sumatran rhinoceros, and several extinct species. The genus likely originated in the Mid to Late Pliocene of Northern Indochina and South China. Many species previously placed in this genus probably belong elsewhere.
Gomphotheres are an extinct group of proboscideans related to modern elephants. They were widespread across Afro-Eurasia and North America during the Miocene and Pliocene epochs and dispersed into South America during the Pleistocene as part of the Great American Interchange. Gomphotheres are a paraphyletic group that is ancestral to Elephantidae, which contains modern elephants, as well as Stegodontidae. While most famous forms such as Gomphotherium had long lower jaws with tusks, which is the ancestral condition for the group, some later members developed shortened (brevirostrine) lower jaws with either vestigial or no lower tusks, looking very similar to modern elephants, an example of parallel evolution, which outlasted the long-jawed gomphotheres. By the end of the Early Pleistocene, gomphotheres became extinct in Afro-Eurasia, with the last two genera, Cuvieronius ranging from southern North America to western South America, and Notiomastodon having a wide range over most of South America until the end of the Pleistocene around 12,000 years ago, when they became extinct following the arrival of humans.
Gigantopithecus is an extinct genus of ape that lived in southern China from 2 million to approximately 300-200,000 years ago during the Early to Middle Pleistocene, represented by one species, Gigantopithecus blacki. Potential identifications have also been made in Thailand, Vietnam, and Indonesia. The first remains of Gigantopithecus, two third molar teeth, were identified in a drugstore by anthropologist Ralph von Koenigswald in 1935, who subsequently described the ape. In 1956, the first mandible and more than 1,000 teeth were found in Liucheng, and numerous more remains have since been found in at least 16 sites. Only teeth and four mandibles are known currently, and other skeletal elements were likely consumed by porcupines before they could fossilise. Gigantopithecus was once argued to be a hominin, a member of the human line, but it is now thought to be closely allied with orangutans, classified in the subfamily Ponginae.
The Levallois technique is a name given by archaeologists to a distinctive type of stone knapping developed around 250,000 to 300,000 years ago during the Middle Palaeolithic period. It is part of the Mousterian stone tool industry, and was used by the Neanderthals in Europe and by modern humans in other regions such as the Levant.
Hoabinhian is a lithic techno-complex of archaeological sites associated with assemblages in Southeast Asia from late Pleistocene to Holocene, dated to c. 10,000–2000 BCE. It is attributed to hunter-gatherer societies of the region and their technological variability over time is poorly understood. In 2016 a rockshelter was identified in Yunnan (China), where artifacts belonging to the Hoabinhian technocomplex were recognized. These artifacts date from 41,500 BCE.
Mammuthus meridionalis, sometimes called the southern mammoth, is an extinct species of mammoth native to Eurasia, including Europe, during the Early Pleistocene, living from around 2.5 million years ago to 800,000 years ago.
Émile Licent was a French Jesuit trained as a natural historian. He spent more than twenty-five years researching in Tianjin. His expeditions spread across various parts of Northern and Central China.
Border Cave is an archaeological site located in the western Lebombo Mountains in Kwazulu-Natal. The rock shelter has one of the longest archaeological records in southern Africa, which spans from the Middle Stone Age to the Iron Age.
The archaeological site Niederbieber is an important representative of the Federmesser culture. Dating to the end of the Pleistocene, the site is one of the most extensively excavated archaeological sites dating to the late Upper Palaeolithic. Finds and features are extraordinarily well preserved as the site was protected by fallout from the Laacher See volcanic eruption approximately 12,900 years ago. Comprehensive archaeological studies have provided a detailed view of activities and settlement dynamics of hunter-gatherer groups at the end of the ice age.
The Swan Point Archeological Site is located in eastern central Alaska, in the Tanana River watershed. It is one of a collection of sites in the area that have yielded the oldest evidence of human habitation in the state, in addition to megafauna no longer found in Alaska, such as wapiti (elk), bison, and woolly mammoth. Finds co-located with human artifacts at the site have given radiocarbon dates of 14,000 years, indicating the site was occupied around 12,000 BCE.
Xujiayao, located in the Nihewan Basin in China, is an early Late Pleistocene paleoanthropological site famous for its archaic hominin fossils.
The Gueldaman caves are a prehistoric mountain ridge on the right bank of the Soummam valley in Algeria. The ridge consists of a large karst network with several natural caves, which is situated near the town of Akbou, Béjaïa Province, in the western part of the Babor Mountains in the Tell Atlas range. The location spans over 7 km (4.3 mi) and varies in altitude between 556 m (1,824 ft) to 898 m (2,946 ft). Adrar is a Berber (Amazigh) term for mountain, possibly a cognate of the toponym Atlas. Gueldaman is a Numidian water deity.
Round Head rock art is the earliest painted, monumental form of Central Saharan rock art, which was largely created from 9500 BP to 7500 BP and ceased being created by 3000 BP. The Round Head Period is preceded by the Kel Essuf Period and followed by the Pastoral Period. Round Head rock art number up to several thousand depictions in the Central Sahara. Human and undomesticated animal artforms are usually portrayed, with a variety of details, in painted Round Head rock art. Painted Round Head rock art and engraved Kel Essuf rock art usually share the same region and occasionally the same rockshelters. The Round Head rock art of Tassili and the surrounding mountainous areas bear considerable similarity with traditional Sub-Saharan African cultures.
Mochena Borago is a rockshelter and archaeological site situated on the western slope of Mount Damota, nearest to the town of Wolaita Sodo in Ethiopia, located in the Southern Nations, Nationalities and Peoples Region. The site is well-dated, with 59 radiocarbon dates, which gives it one of the most secure chronologies among Late Pleistocene sites in the Horn of Africa and Eastern Africa. It is one of only a few African sites found with intact deposits dating to Marine Isotope Stage (MIS) 3 outside of South Africa, and was potentially a refugium for hunter-gatherering peoples during the cold and arid period of MIS 4. This makes it an important research site for testing the "refugium theory," which states that over the past 70,000 years, during cold, arid conditions, like those of the Last Glacial Maximum and MIS 4, humans sought refuge in the mountains of the southwest Ethiopian Highlands, which received higher rainfall, making them more habitable than the surrounding areas. Research at Mochena Borago is helping to reconstruct human behavior during the Late Pleistocene, and the paleoenvironment that Homosapiens would have inhabited at this time in the Horn of Africa.
