The excavated area of the mound was demarcated into two zones on the basis of occupation and elevation.
Northern sector of the mound is nearer to the sea coast while the southern sector is farther away from the coast.
The ceramic find of crockery and cooking vessels found in the northern sector were indicative of mass feeding of sailors and traders who camped there.
Wine stored in amphorae was the principal item imported from the western countries during the later part of the 2nd century BCE.

According to Wheeler the finds from the northern and southern part of the mound belong to the period from the later part of the 1st century BCE to the 1st and 2nd centuries CE.
Identified structures include:
A brick and lime mortar plaster structure of oblong shape 45 metres (148 ft) in length, with a divide wall, used as a storehouse in the southern part
Two walled enclosures with ponds and drainage systems in the northern part of the mound that could indicate of dyeing operations that used vats to dye muslin for export
Pottery, both local and Mediterranean, such as amphorae and Arrentine ware that belonged to the Terra Sigillata (stamped pottery) of the 1st century BCE, which went out of use by 50 CE
Pink amphorae jars used to store wine or oil with two handles and a yellow slip, found in all layers of excavations
Smaller objects include a wheel-turned blackware ceramic, a few terracotta figurines, shell beads, gems, gold, terracotta, iron nails, copper percussion beater, red fragment of a Roman lamp shade, an engraved emblem of emperor Augustus, an ivory handle, and a wooden toy boat.
Based on these antiquities Wheeler concluded that the Arikamedu was a Greek (Yavana) trading station.
However, recent excavations by Begley have altered this assessment.

The buildings in the northern part of the mound indicative urbanization, with people of different ethnic groups—Indian and non-Indian—but it has not been possible to date them in view of the limited depth of excavations.
