On the scaling relationship between enamel prism length and enamel thickness in primate molars: a comment.
As part of a larger study we developed a computer programme which allows the recreation of the complex 3-dimensional arrangement of prisms. Data presented in these earlier publications are re-analyzed to assess the relationship between projected prism length (i. e., enamel thickness) and the true prism length. Across primates, proportional prism deviation increases as the enamel becomes thicker. This supports suggestions that prism decussation may be particularly marked in large-bodied and thick-enameled species. There are differences, however, in scaling relationships between species, which correspond to the species' dietary adaptations. Finally, the findings highlight the importance of employing species-specific correction factors for the calculation of prism length (i.e., life-span of the ameloblast) for life history enquiry.
