Artificial neural networks predict perikymata counts on worn teeth from two key paleoanthropological sites: Atapuerca (Spain) and Omo valley (Ethiopia)

Abstract

Long-growth markers on the enamel surface, perikymata, are key to assess enamel formation times of teeth. It is well known that crown formation times varied through evolutionary time, as Australopithecus and Paranthropus have significantly lower number of perikymata than Homo species, indicating faster rates of ename growth.
