amino-acid racemization: a method used in the dating of both human and animal bone.Its special significance is that with a small sample (10g) it can be applied to material up to 100,000 years old, i.e. ancillary sample: any non-artifactual materials collected by archaeologists to aid in dating, paleoenvironmental reconstruction, or other interpretations - e.g.
brain endocasts: these are made by pouring latex rubber into a skull, 50 as to produce an accurate image of the inner surface of the cranium.
The subject is generally broken down into three subdisciplines: biological (physical) anthropology, cultural (social) anthropology, and archaeology.
archaeological culture: a constantly recurring assemblage of artifacts assumed to be representative of a particular set of behavioral activities carried out at a particular time and place (cf. archaeomagnetic dating: sometimes referred to as paleomagnetic dating.
artifact: any manually portable product of human workmanship (see feature).
In its broadest sense includes tools, weapons, ceremonial items, art objects, all industrial waste, and all floral and faunal remains modified by human activity.
