Bone Carving
Grazing caribou made in Alaska 1910 - Linden Museum Bone carving is creating art, tools, and other goods by carving animal bones, antlers, and horns. It can result in the ornamentation of a bone by engraving, painting or another technique, or the creation of a distinct formed object. Bone carving has been practiced by a variety of world cultures, sometimes as a cheaper, and recently a legal, substitute for ivory carving. As a material it is inferior to ivory in terms of hardness, and so the fine detail that is possible, and lacks the "lustrous" surface of ivory. The interior of bones are softer and even less capable of a fine finish, so most uses are as thin plaques, rather than sculpture in the round. But it must always have been much easier to obtain. It was important in prehistoric art, with notable figures like the ''Swimming Reindeer'', made of antler, and many of the Venus figurines. The Anglo-Saxon Franks Casket is a whale bone casket imitating earlier ivory on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carving
Carving is the act of using tools to shape something from a material by scraping away portions of that material. The technique can be applied to any material that is solid enough to hold a form even when pieces have been removed from it, and yet soft enough for portions to be scraped away with available tools. Carving, as a means for making stone or wooden sculpture, is distinct from methods using soft and malleable materials like clay, fruit, and melted glass, which may be shaped into the desired forms while soft and then harden into that form. Carving tends to require much more work than methods using malleable materials.Daniel Marcus Mendelowitz, ''Children Are Artists: An Introduction to Children's Art for Teachers and Parents'' (1953), p. 136. Kinds of carving include: * Bone carving * Chip carving * Fruit carving * Gourd carving or gourd art * Ice carving or ice sculpture * Ivory carving * Stone carving ** Petroglyph * Vegetable carving ** Thaeng yuak (Banana stalk carv ...

Scrimshaw
Scrimshaw is scrollwork, engravings, and carvings done in bone or ivory. Typically it refers to the artwork created by whalers, engraved on the byproducts of whales, such as bones or cartilage. It is most commonly made out of the bones and teeth of sperm whales, the baleen of other whales, and the tusks of walruses. It takes the form of elaborate engravings in the form of pictures and lettering on the surface of the bone or tooth, with the engraving highlighted using a pigment, or, less often, small sculptures made from the same material. However, the latter really fall into the categories of ivory carving, for all carved teeth and tusks, or bone carving. The making of scrimshaw probably began on whaling ships in the late 18th century and survived until the ban on commercial whaling. The practice survives as a hobby and as a trade for commercial artisans. A maker of scrimshaw is known as a ''scrimshander''. The word first appeared in the logbook of the brig ''By Chance'' in 182 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baleen
Baleen is a filter-feeding system inside the mouths of baleen whales. To use baleen, the whale first opens its mouth underwater to take in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale. Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails, skin and hair. Baleen is a skin derivative. Some whales, such as the bowhead whale, have longer baleen than others. Other whales, such as the gray whale, only use one side of their baleen. These baleen bristles are arranged in plates across the upper jaw of whales. Depending on the species, a baleen plate can be long, and weigh up to . Its hairy fringes are called baleen hair or whalebone hair. They are also called baleen bristles, which in sei whales are highly calcified, with calcification functioning to increase their stiffness. Baleen plates are broader at the gumline (base). The plates have bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ScienceAlert
ScienceAlert is an independently run online publication and news source that publishes articles featuring scientific research, discoveries and outcomes. The site was founded in 2004 by Julian Cribb, a science writer, to aggregate research findings from Australian universities, and expanded in 2006 when ex-Microsoft programmer Chris Cassella took on the project of developing the website. It has readership that ranges from 11.5m to 26.5m per month. Science journalist Fiona MacDonald has been CEO since 2017. History Science communicator Julian Cribb founded ScienceAlert in 2004. The website was borne of his “concern at the lack of information available about what Australians and New Zealanders achieve in science.” Chris Cassella, a former programmer for Microsoft, joined the site in order to develop new webtools. He took on this work as part of a Master’s thesis in Science Communication at Australia National University, where Cribb was a professor. Initially, ScienceAlert’ ...

Neanderthal
Neanderthals (, also ''Homo neanderthalensis'' and erroneously ''Homo sapiens neanderthalensis''), also written as Neandertals, are an Extinction, extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago. While the "causes of Neanderthal disappearance about 40,000 years ago remain highly contested," demographic factors such as small population size, inbreeding and genetic drift, are considered probable factors. Other scholars have proposed competitive replacement, assimilation into the modern human genome (bred into extinction), great climate change, climatic change, disease, or a combination of these factors. It is unclear when the line of Neanderthals split from that of Early modern human, modern humans; studies have produced various intervals ranging from 315,000 to more than 800,000 years ago. The date of divergence of Neanderthals from their ancestor ''Homo heidelbergensis, H. heidelbergensis'' is also unclear. The oldest potential ...

Franks Casket
The Franks Casket (or the Auzon Casket) is a small Anglo-Saxon whale's bone (not "whalebone" in the sense of baleen) chest from the early 8th century, now in the British Museum. The casket is densely decorated with knife-cut narrative scenes in flat two-dimensional low-relief and with inscriptions mostly in Anglo-Saxon runes. Generally thought to be of Northumbrian origin, it is of unique importance for the insight it gives into early Anglo-Saxon art and culture. Both identifying the images and interpreting the runic inscriptions has generated a considerable amount of scholarship. The imagery is very diverse in its subject matter and derivations, and includes a single Christian image, the Adoration of the Magi, along with images derived from Roman history ( Emperor Titus) and Roman mythology ( Romulus and Remus), as well as a depiction of at least one legend indigenous to the Germanic peoples: that of Weyland the Smith. It has also been suggested that there may be an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
