Geometric morphometric dataset used in: Olive diversity in Pompeii: morphometrics of fuel-derived stones (c. 50-79 CE) from bakeries as markers of domestication and local production

The dataset includes x- and y-coordinates describing closed outlines of the lateral and dorsal views of each olive stone (stored as RDS files), as well as the 48 elliptic Fourier coefficients derived from these outlines after normalization (available as both RDS and CSV files).

The full acquisition and processing protocol is described in the associated publication. The dataset comprises both a modern reference collection, consisting of 3,258 olive stones from 110 domesticated and wild accessions, and an archaeological dataset including 511 olive stones recovered from two bakeries in Pompeii, dating to the second half of the 1st century CE. A complete R script used to perform all statistical analyses and reproduce the results is also provided in this repository.
