Four (4) samples of so-called Byzantine Globular Amphorae from the excavation of the rural farm at Ain Wassel (High Tunisian Tell) have been considered for organic residue analysis via gas chromatography-mass spectrometry (GC-MS) in order to better understand the function of this type of transport and storage container and shed new light on still poorly understood trade and consumption practices in Late Antique/Early Medieval North Africa. The content of this typological group of amphorae dating to the 7th-8th(?) century AD is still unknown. Following samples of the bottom of "anfora a fondo umbonato e ombelicato" (Maurina 2019), corresponding to the type Bonifay 65 (Bonifay 2004) have been analyzed in this study: Maurina 2019, Fig. 4.9, 14-17. The obtained results are available here in tabular form.
