Boxplot showing the (A) δ¹³C and (B) δ¹⁵N values of fauna samples from Early Neolithic to Copper Age. Faunal data in this study were supplemented by published data of Early Neolithic [42,76], Middle Neolithic [22,25] and Copper Age [25] samples of the GHP. Domesticated fauna results on the left in yellow; wild fauna on the right in green. The dots within the boxes represent individual values of the samples; the horizontal line within the boxrepresents the median value; the vertical lines represent the range of data; and the asterisks are the possible outliers.
