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. In relation to site stra ...

Great White Shark
The great white shark (''Carcharodon carcharias''), also known as the white shark, white pointer, or simply great white, is a species of large Lamniformes, mackerel shark which can be found in the coastal surface waters of all the major oceans. It is the only known surviving species of its genus ''Carcharodon''. The great white shark is notable for its size, with the largest preserved female specimen measuring in length and around in weight at maturity. However, most are smaller; males measure , and females measure on average. According to a 2014 study, the lifespan of great white sharks is estimated to be as long as 70 years or more, well above previous estimates, making it one of the longest lived Chondrichthyes, cartilaginous fishes currently known. According to the same study, male great white sharks take 26 years to reach sexual maturity, while the females take 33 years to be ready to produce offspring. Great white sharks can swim at speeds of 25 km/h (16 mph ...

Tiger Shark
The tiger shark (''Galeocerdo cuvier'') is a species of ground shark, and the only extant member of the genus '' Galeocerdo'' and family Galeocerdonidae. It is a large apex predator, with females capable of attaining a length of over . Populations are found in many tropical and temperate waters, especially around central Pacific islands.

It also has a reputation as a "garbage eater", consuming a variety of inedible, man-made objects that linger in its stomach. Tiger sharks have only one recorded natural predator, the orca. It is considered a near-threatened species because of finning and fishing by ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for Chronological dating, determining the age of an object containing organic material by using the properties of carbon-14, radiocarbon, a radioactive Isotopes of carbon, isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Atmosphere of Earth, Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of w ...

Dogū
are small humanoid and animal figurines made during the later part of the Jōmon period (14,000–400 BC) of prehistoric Japan. ''Dogū'' come exclusively from the Jōmon period, and were no longer made by the following Yayoi period. There are various styles of ''dogū'', depending on the exhumation area and time period. The National Museum of Japanese History estimates that the total number of ''dogū'' is approximately 15,000, while ''The Japan Times'' places the figure at approximately 18,000. ''Dogū'' were made across all of Japan, except Okinawa. Most of the ''dogū'' have been found in eastern Japan and it is rare to find one in western Japan. The purpose of the ''dogū'' remains unknown and should not be confused with the clay ''haniwa'' funerary objects of the Kofun period (250 – 538 C.E.). Everyday ceramic items from the period are called Jōmon pottery. Origins Some scholars theorize the ''dogū'' acted as effigies of people, that manifested some kind of ...

Grave Goods
Grave goods, in archaeology and anthropology, are items buried along with a body. They are usually personal possessions, supplies to smooth the deceased's journey into an afterlife, or offerings to gods. Grave goods may be classed by researchers as a type of votive deposit. Most grave goods recovered by archaeologists consist of inorganic objects such as pottery and stone and metal tools, but organic objects that have since decayed were also placed in ancient tombs. If grave goods were to be useful to the deceased in the afterlife, then favorite foods or everyday objects were supplied. Oftentimes, social status played a role in what was left and how often it was left. Funerary art is a broad term but generally means artworks made specifically to decorate a burial place, such as miniature models of possessions - including slaves or servants - for "use" in an afterlife. (Ancient Egypt sometimes saw the burial of real servants with the deceased. Similar cases of human sacrifice of ...

Tooth Ablation
Tooth ablation (also known as ''tooth evulsion'', ''dental evulsion'' and ''tooth extraction'') is the deliberate removal of a person's healthy teeth, and has been recorded in a variety of ancient and modern societies around the world. This type of dental modification is visually very striking and immediately obvious to other people from the same or different communities. There are numerous reasons for performing tooth ablation, including group identification, ornamentation, and rites of passage such as coming of age, marriage and mourning. The social meaning of tooth evulsion is likely to remain unknown for ancient populations and may have changed over time within those groups. Dental evulsion can significantly affect the emergence, occlusion and wear patterns of the remaining teeth. Procedure There are various techniques used to perform dental evulsion; however, regardless of the technique, dental evulsion could not have been achieved without causing pain and a risk of infec ...

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 line ...

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 Artifact (archaeology), artifacts (portable objects made or modified by humans), Feature (archaeology), features (non-portable modifications to the site itself such as post molds, burials, and hearths), Ecofact, 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 se ...
