Experimental replications show that ridge breadth measurements from fingerp
rints on archaeological artifacts call be used to estimate the age of the i
ndividual who produced the prints. While the greatest amount of variability
in human ridge breadth is due to the growth during development from birth
to adulthood, there is also variability due to hand and body size, sex, and
ethnicity. Despite these confounding variables, the variability due to age
is great enough to allow the separation of children's prints from those of
adults using ridge breadths. The utility of this measurement is illustrate
d with a short case study using ceramic: vessels and figurines from norther
n Arizona. This discovery has great potential for, illuminating some of the
roles that children played in prehistory.
