Kotehashi Shell Mound
The is an archaeological site in the Satsukigaoka neighborhood of Hanamigawa ward of the city of Chiba, Chiba Prefecture, in the Kantō region of Japan containing a Jōmon period shell midden. It was designated a National Historic Site of Japan in 1981. Overview During the early to middle Jōmon period (approximately 4000 to 2500 BC), sea levels were five to six meters higher than at present, and the ambient temperature was also 2 deg C higher. During this period, the Kantō region was inhabited by the Jōmon people, many of whom lived in coastal settlements. The middens associated with such settlements contain bone, botanical material, mollusc shells, sherds, lithics, and other artifacts and ecofacts associated with the now-vanished inhabitants, and these features, provide a useful source into the diets and habits of Jōmon society. Most of these middens are found along the Pacific coast of Japan. Of the approximately 2400 shell middens throughout Japan, about 120 are ...

Feature (archaeology)
In archaeological excavation, a feature is a collection of one or more contexts representing some human non-portable activity, such as a hearth or wall. Features serve as an indication that the area in which they are found has been interfered with in the past, usually by humans. Features are distinguished from artifacts in that they cannot be separated from their location without changing their form. Artifacts are portable, while features are non-portable. Artifacts and features can both be made from any available material, with the primary distinction being portability. Features and artifacts differ from ecofacts. Ecofacts are natural remains, such as plants and animals. Types Features are categorized by the time period, as either historic or prehistoric. Prehistoric archaeology refers to the time in history before human life was recorded or documented, while historic archaeology refers to the time period where there was a documented human past.

Stone Tool
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. One simple form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Raccoon Dog
The Japanese raccoon dog (''Nyctereutes viverrinus''), also known as the ''tanuki'' ( ja, , , ), is a species of canid endemic to Japan. It is one of two species in the genus ''Nyctereutes'', alongside the common raccoon dog (''N. procyonoides''), of which it was formerly thought to be a subspecies. The Japanese raccoon dog has a relatively smaller stomach and shorter fur of lesser insulation value than mainland raccoon dogs. A rare, white colour type can also be found. Within Japanese folklore, the ''tanuki'' have had a significant role since ancient times. The legendary ''tanuki'' are reputed to be mischievous and jolly, masters of disguise and shapeshifting but somewhat gullible and absentminded. The animals have also been common in Japanese art, particularly as subjects for statues. Japanese etymology While ''tanuki'' are prominent in Japanese folklore and proverbs, they were not always clearly distinguished from other animals with a similar appearance. In local dialects, '' ...

Archaeological Excavation
In archaeology, excavation is the exposure, processing and recording of archaeological remains. An excavation site or "dig" is the area being studied. These locations range from one to several areas at a time during a project and can be conducted over a few weeks to several years. Excavation involves the recovery of several types of data from a site. This data includes artifacts (portable objects made or modified by humans), features (non-portable modifications to the site itself such as post molds, burials, and hearths), ecofacts (evidence of human activity through organic remains such as animal bones, pollen, or charcoal), and archaeological context (relationships among the other types of data).Kelly&Thomas (2011). ''Archaeology: down to earth'' (4th ed.). Belmont, Calif.: Wadsworth, Cengage Learning. Before excavating, the presence or absence of archaeological remains can often be suggested by, non-intrusive remote sensing, such as ground-penetrating radar. Basic informat ...
