    Fourier transformation rapidly characterizes primate dental microwear. Different wear patterns, like scratches versus pits, yield distinct Fourier transforms, reflecting species-specific diets.

    Area of Science:

    • Paleontology
    • Bioengineering
    • Primate Ecology

    Background:

    • Dental microwear analysis is crucial for inferring primate diets and behaviors.
    • Traditional methods for analyzing microwear can be time-consuming and subjective.
    • Fourier transformation offers a novel, quantitative approach to pattern recognition.

    Purpose of the Study:

    • To introduce and validate Fourier transformation as a method for analyzing primate dental microwear.
    • To differentiate between distinct microwear patterns using Fourier analysis.
    • To explore the relationship between microwear patterns and primate diets.

    Main Methods:

    • Numerical Fourier transformation applied to digital images of primate teeth.
    • Analysis of two-dimensional power spectra generated from wear patterns.

  • Comparison of Fourier transforms from primate dental microwear with artificial test patterns (linear vs. dots).

    • Main Results:

    • Fourier transformation successfully distinguished between linear and dot test patterns.
    • Dental microwear patterns of *Ateles geoffroyi* (spider monkey) resembled the Fourier transform of linear features (scratches).
    • Dental microwear patterns of *Chiropotes satanas* (bearded saki) resembled the Fourier transform of dot patterns (pits).

    Conclusions:

    • Fourier transformation provides a rapid and replicable method for characterizing primate dental microwear.
    • The distinct Fourier transforms correlate with known dietary differences between *Ateles* and *Chiropotes*.
    • This technique has potential for reconstructing primate feeding ecology from fossil teeth.
