Plots of TAG information based on HT-GC data of individual pottery samples from Palermo sites (CSP, GA and PB) and Castronovo (CLESP) with interpretations based on fatty acid isotope values.

The dispersion factor (DF) and average carbon number (M) were calculated using statistical equations outlined by Mirabaud et al. [52]. Shapes represent ruminant dairy (●) based on Δ¹³C values <-3.3‰, ruminant adipose (◆) based on Δ¹³C values between -3.3‰ and -1.0 ‰ and non-ruminant (■) based on Δ¹³C above -1.0‰ [45].
