Gender differs from anatomical sex because it refers to a social
role or identity associated with sex but not invariably determined
by the physical body. Genders encountered in archaeology can be
masculine, feminine, or culturally specific roles that are some
mixture of the two. Archaeologically, one sexes physical remains by
examining bones, tooth size, or DNA. Gender is indicated by
artifacts such as dress or tools. Crossover or alternate gender
identities are to be suspected when some burials or depictions
deviate significantly from the general pattern. In older excavation
reports, the possibility of gender variance was often not taken
into account. Grave equipment was used to classify bones.
Significant mismatches between artifacts and bones were normalized
as things that were out of place, for example "offerings" or
"intrusions."
