This study analyzes 26 pottery fragments from the Shah Qoli Beygi archaeological site, focusing on their typology, technology, and chronological significance within the Lapui phase of prehistoric Fars in the Shiraz Plain. The assemblage, dominated by red fine wares, also includes common wares and evidence of different from the preceding Middle and Late Fars (Bakun) Phase. Variations in color, texture, and manufacturing techniques, including both hand-made and wheel-made forms, are examined. Comparative analysis with other Lapui sites reveals regional trends in pottery production, including the shift towards red fine wares and the prevalence of specific vessel forms. The study highlights the transition and continuity of ceramic traditions during the Lapui phase, emphasizing the site's contribution to understanding the cultural dynamics of the fourth millennium BC in southern Iran.
