Midden Heap
A midden (also kitchen midden or shell heap) is an old dump for domestic waste which may consist of animal bone, human excrement, botanical material, mollusc shells, potsherds, lithics (especially debitage), and other artifacts and ecofacts associated with past human occupation. These features provide a useful resource for archaeologists who wish to study the diets and habits of past societies. Middens with damp, anaerobic conditions can even preserve organic remains in deposits as the debris of daily life are tossed on the pile. Each individual toss will contribute a different mix of materials depending upon the activity associated with that particular toss. During the course of deposition sedimentary material is deposited as well. Different mechanisms, from wind and water to animal digs, create a matrix which can also be analysed to provide seasonal and climatic information. In some middens individual dumps of material can be discerned and analysed. Shells A shell midd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whaleback Shell Midden Gully - 20070722 07986
] A whaleback was a type of cargo steamship of unusual design, with a hull that continuously curved above the waterline from vertical to horizontal. When fully loaded, only the rounded portion of the hull (the "whaleback" proper) could be seen above the waterline. With sides curved in towards the ends, it had a Spoon-shaped bow, spoon bow and a very convex upper deck. It was formerly used on the Great Lakes of Canada and the United States, notably for carrying grain or ore. The sole surviving ship of the "whaleback" design is the , which is docked in Superior, Wisconsin as a museum ship. The term developed in common usage in response to the ship's appearance when fully loaded. A total of 44 such vessels were constructed from 1887 to 1898. All but two were built initially as lake freighters for service on the Great Lakes. Six were built at Duluth, Minnesota; 33 were built at West Superior, Wisconsin; 2 at Brooklyn, New York; one at Everett, Washington; and one at Sunderland, Eng ...

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species. The gastropods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Prehistory
The first human inhabitants of the Japanese archipelago have been traced to prehistoric times around 30,000 BC. The Jōmon period, named after its cord-marked pottery, was followed by the Yayoi period in the first millennium BC when new inventions were introduced from Asia. During this period, the first known written reference to Japan was recorded in the Chinese ''Book of Han'' in the first century AD. Around the 3rd century BC, the Yayoi people from the continent immigrated to the Japanese archipelago and introduced iron technology and agricultural civilization. Because they had an agricultural civilization, the population of the Yayoi began to grow rapidly and ultimately overwhelmed the Jōmon people, natives of the Japanese archipelago who were hunter-gatherers. Between the fourth to ninth century, Japan's many kingdoms and tribes gradually came to be unified under a centralized government, nominally controlled by the Emperor of Japan. The imperial dynasty established at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jōmon Pottery
The is a type of ancient earthenware pottery which was made during the Jōmon period in Japan. The term "Jōmon" () means "rope-patterned" in Japanese, describing the patterns that are pressed into the clay. Outline Oldest pottery in Japan The pottery vessels crafted in Ancient Japan during the Jōmon period are generally accepted to be the oldest pottery in Japan and among the oldest in the world. Dating Odai Yamamoto I site in Aomori Prefecture currently has the oldest pottery in Japan. Excavations in 1998 uncovered forty-six earthenware fragments which have been dated as early as 14,500 BCE (ca 16,500 BP); this places them among the earliest pottery currently known. This appears to be plain, undecorated pottery. Such a date puts the development of pottery before the warming at the end of the Pleistocene. 'Linear-relief' pottery was also found at Fukui Cave Layer III dating to 13,850–12,250 BCE. This site is located in Nagasaki Prefecture, Kyushu. Both linear-r ...

Tokyo, Japan
Tokyo (; ja, 東京, , ), officially the Tokyo Metropolis ( ja, 東京都, label=none, ), is the capital and List of cities in Japan, largest city of Japan. Formerly known as Edo, its metropolitan area () is the most populous in the world, with an estimated 37.468 million residents ; the city proper has a population of 13.99 million people. Located at the head of Tokyo Bay, the prefecture forms part of the Kantō region on the central coast of Honshu, Japan's largest island. Tokyo serves as Economy of Japan, Japan's economic center and is the seat of both the Government of Japan, Japanese government and the Emperor of Japan. Originally a fishing village named Edo, the city became politically prominent in 1603, when it became the seat of the Tokugawa shogunate. By the mid-18th century, Edo was one of the most populous cities in the world with a population of over one million people. Following the Meiji Restoration of 1868, the imperial capital in Kyoto was mov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omori Shell Mounds
The Ōmori Shell Mounds () are the middens, located in Ōmori, on the border of Shinagawa and Ōta, Tokyo, Japan. Overview The shell mounds had been known to the local people for a long time. In 1877, the American zoologist Edward S. Morse (who would later teach zoology at the University of Tokyo) came to Japan, and, on the second day of his arrival while riding Japan's first railway from Yokohama to Tokyo (founded in 1872), "found" these mounds and instantly felt their importance. Dr. Morse with his assistants later excavated these mounds from the Jōmon Period and published his paper in 1879, which launched Japan's modern archeology. These shell mounds are now part of Ōmori Shell Mounds Garden, open to the public. In 1955, the sites were registered as Japan's Historic Sites. The shells, pottery, and other items that Dr. Morse excavated are mostly stored at the University Museum of the University of Tokyo and are Japan's Important Cultural Property.

Edward Sylvester Morse
Edward Sylvester Morse (June 18, 1838 – December 20, 1925) was an American zoologist, archaeologist, and orientalist. He is considered the "Father of Japanese archaeology." Early life Morse was born in Portland, Maine to Jonathan Kimball Morse and Jane Seymour (Becket) Morse. His father was a Congregationalist deacon who held strict Calvinist beliefs. His mother, who did not share her husband's religious beliefs, encouraged her son's interest in the sciences. An unruly student, Morse was expelled from all but one of the schools he attended in his youth — the Portland village school, the academy at Conway, New Hampshire, in 1851, and Bridgton Academy in 1854 (for carving on desks). He also attended Gould Academy in Bethel, Maine. At Gould Academy, Morse came under the influence of Dr. Nathaniel True who encouraged Morse to pursue his interest in the study of nature. He preferred to explore the Atlantic coast in search of shells and snails, or go to the field to stud ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alkaline
In chemistry, an alkali (; from ar, القلوي, al-qaly, lit=ashes of the saltwort) is a base (chemistry), basic, ionic compound, ionic salt (chemistry), salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English language, English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the acid-base reaction theories#Arrhenius theory, Arrhenius definition of a base, and they are still among the most common bases. Etymology The word "alkali" is derived from Arabic ''al qalīy'' (or ''alkali''), meaning ''the calcined ashes'' (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stone Tools
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 (particularly Stone Age) 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. Stone has been used to make a wide variety of different tools throughout history, including arrowheads, spearheads, hand axes, and querns. Stone tools may be made of either ground stone or knapped stone, the latter fashioned by a flintknapper. Knapped stone tools are made from cryptocrystalline materials such as chert or flint, radiolarite, chalcedony, obsidian, basalt, and quartzite via a process known as lithic reduction.
