ArrowheadAn arrowhead or point is the usually sharpened and hardened tip of an arrow, which contributes a majority of the projectile mass and is responsible for impacting and penetrating a target, as well as to fulfill some special purposes such as signaling. The earliest arrowheads were made of stone and of organic materials; as human civilizations progressed, other alloy materials were used. Arrowheads are important archaeological artifacts; they are a subclass of projectile points.
Varna cultureThe Varna culture was a Chalcolithic culture of northeastern Bulgaria, dated ca. 4500 BC, contemporary and closely related with the Gumelnița culture. The oldest golden artifacts in the world (4600 BC - 4200 BC) are found in the Necropolis of Varna - grave offerings on exposition in Varna Archaeological Museum The site was accidentally discovered in October 1972 by excavator operator Raycho Marinov. Research excavation was under the direction of Mihail Lazarov and Ivan Ivanov.
Yangshao cultureThe Yangshao culture (仰韶文化, pinyin: Yǎngsháo wénhuà) was a Neolithic culture that existed extensively along the middle reaches of the Yellow River in China from around 5000 BC to 3000 BC. The culture is named after the Yangshao site, the first excavated site of this culture, which was discovered in 1921 in Yangshao town, Mianchi County, Sanmenxia, western Henan Province by the Swedish geologist Johan Gunnar Andersson (1874–1960). The culture flourished mainly in the provinces of Henan, Shaanxi and Shanxi.
Holocene climatic optimumThe Holocene Climate Optimum (HCO) was a warm period that occurred in the interval roughly 9,500 to 5,500 years ago BP, with a thermal maximum around 8000 years BP. It has also been known by many other names, such as Altithermal, Climatic Optimum, Holocene Megathermal, Holocene Optimum, Holocene Thermal Maximum, Hypsithermal, and Mid-Holocene Warm Period. The warm period was followed by a gradual decline, of about 0.1 to 0.3 °C per millennium, until about two centuries ago.
Franchthi CaveFranchthi Cave or Frankhthi Cave (Σπήλαιον Φράγχθι) is an archaeological site overlooking Kiladha Bay, in the Argolic Gulf, opposite the village of Kiladha in southeastern Argolis, Greece. Humans first occupied the cave during the Upper Paleolithic, appearing around 38,000 BC (and possibly earlier.) Groups continued to live in or seasonally visit the cave throughout the Mesolithic and Neolithic eras, with occasional short episodes of apparent abandonment.
Halaf cultureThe Halaf culture is a prehistoric period which lasted between about 6100 BC and 5100 BC. The period is a continuous development out of the earlier Pottery Neolithic and is located primarily in the fertile valley of the Khabur River (Nahr al-Khabur), of south-eastern Turkey, Syria, and northern Iraq, although Halaf-influenced material is found throughout Greater Mesopotamia. While the period is named after the site of Tell Halaf in north Syria, excavated by Max von Oppenheim between 1911 and 1927, the earliest Halaf period material was excavated by John Garstang in 1908 at the site of Sakce Gözü.
FigurineA figurine (a diminutive form of the word figure) or statuette, is a small, three-dimensional sculpture that represents a human, deity or animal, or, in practice, a pair or small group of them. Figurines have been made in many media, with clay, metal, wood, glass, and today plastic or resin the most significant. Ceramic figurines not made of porcelain are called terracottas in historical contexts. Figures with movable parts, allowing limbs to be posed, are more likely to be called dolls, mannequins, or action figures; or robots or automata, if they can move on their own.
SpondylusSpondylus is a genus of bivalve molluscs, the only genus in the family Spondylidae. They are known in English as spiny oysters or thorny oysters (though they are not, in fact, true oysters). In addition to its significance in the pre-Columbian times, Spondylus crassiquama was also an important part of Aztec culture. Spondylus amongst Aztecs included: art, jewelry, statues, religious motifs, and at times currency. One example of Spondylus used in art is the double-headed serpent which can be seen amongst images on the right of the page.
Liangzhu cultureThe Liangzhu culture or Liangzhu civilization (ˈljɑːŋˈdʒuː; 3300–2300 BC) was the last Neolithic jade culture in the Yangtze River Delta of China. The culture was highly stratified, as jade, silk, ivory and lacquer artifacts were found exclusively in elite burials, while pottery was more commonly found in the burial plots of poorer individuals. This division of class indicates that the Liangzhu period was an early state, symbolized by the clear distinction drawn between social classes in funeral structures.
Xinglongwa cultureThe Xinglongwa culture (興隆洼文化) (6200–5400 BC) was a Neolithic culture in northeastern China, found mainly around the Inner Mongolia-Liaoning border at the Liao River basin. Xinglongwa pottery was primarily cylindrical and baked at low temperatures. The Xinglongwa culture showed several signs of communal planning. At three Xinglongwa sites, houses were built in rows. Several Xinglongwa sites also featured a large central building. In addition, several Xinglongwa sites were surrounded by ditches.
