context. In Archaeology it has been used to various ends in the subdisciplines of Zooarchaeology and Bioarchaeology. In zooarchaeology the main goal of osteometry is taxonomic determination and, to a lesser extent, determination of sex. The most useful elements to measure in sex determination are the pelvis and cranium.
Jaco Weinstock, 1991 Usually it is very difficult to discriminate between different species of the same genus or family (e.g. South American

s), and the statistical analysis of osteometric parameters is quite useful. In bioarchaeology osteometry is useful to help answer many anthropological questions about past human populations. For example, it may be used to determine kinship, sex, the degree of sexual dimorphism (which may be used to answer questions related to lack of nutrition) and to some extent ethnicity. Osteometry is also used in the identification of human remains, particularly in commingled assemblages. It's used in addition to DNA analysis for individual identification.
John E. Byrd, Carrie B. LeGarde, 2014, p. 167-191 There are many problems around the interpretation of osteometric data: loose replicability of the measurements, problems relative to the phenotypic variations between subpopulations of one species, and others.
