Artifacts are any objects found at sites, made by people and that can easily be moved around, such as pottery or stone tools. Pottery is also sometimes called ceramics. Archaeologists rarely find whole pots, and call the broken pieces sherds. In Oneota archaeology, shape and decoration of pottery are very important for classification. Most Oneota pots have shell-tempering with broadly incised lines, often in chevron patterns.
Stone tools come in a variety of forms, both chipped and ground.
Common chipped stone tools are projectile points such as arrow, spear or lance points, but there is a whole variety of other chipped stone artifacts. Ground stone tools might include axes or pipes. Features are objects made by people that cannot easily be moved such as houses, mounds or fireplaces. Some people consider burials to be features. Ecofacts are types of environmental information that can be used to give an idea about the environment of an area at the time people lived there and about foods people ate.
