[1] Evteev A. A. A method for assessing the age-at-death of infants based on craniofacial measurements // International Symposium on Funerary Anthropology “Homines, Funera, Astra” Sixth edition: Death and Children from Prehistory to Middle Ages. — Alba Iulia, 2017. — P. 12–12. The estimation of age of infant skeletons is usually based on the dental development and, to a lesser extent, on the postcranial metrics. The former is considered more reliable due to its stronger genetic determination and lesser susceptibility to the influence of environmental factors. But numerous studies show that dental development also displays a high level of inter-individual variability. Thus, the age of infants and small children is usually estimated in the quite broad range. A possibility to increase the precision of age estimation in infants might be the use of cranial metrics. The first year of life is the time of most rapid growth in all craniofacial dimensions which abruptly slows down during the second year of life. Noteworthy, growth trajectories of many measurements differ from each other substantially and are not linear. It means that based on the combination of the levels of maturation of different craniofacial dimensions in a particular infant skull it might be possible to give a quite narrow estimation of his age. In this study, a large sample of high resolution clinical CT scans is used to calculate discriminant functions allowing for a precise estimation of infant age using craniofacial measurements. The sample includes 146 CT datasets of boys of the 2nd to 6th years of life and 101 dataset of infants (boys) of the 1st year of life. The linear measurements employed describe the main morphological features of the facial skeleton and are commonly used in craniological studies. Most of them can be easily measured even on fragmentary specimens. The functions were then tested on forensic samples with the documented age-at-death of individuals. The results of these tests have shown that, despite methodological and inter-population differences, the functions can be successfully applied for the estimation of age of infant skeletal individual.
