Determination of the Species from Skeletal Remains Through Histomorphometric Evaluation and Discriminant Analysis

In situations where the skeletal remains found are too fragmented, it is necessary to assess the human origin of such remains; for this purpose, various parameters are used, both anatomical and histological. The objective of the present study is to evaluate the various histomorphometric parameters t...
