The extensive findings of glass and stone beads at the site provided Begley the link to Arikamedu's history. She identified the beads as "Indo-Pacific" beads crafted at Arikamedu. Based on the antiquities and structural features from the excavations, Begley and Raman established a revised sequence of six major periods of occupation of the site. Finds of new variety of Roman Amphorae ware also facilitated revision of the dates of occupancy. They have also inferred that the site has been in continuous occupation since at least 2nd or 3rd century BCE to much more recent times.
