Researchers in the Sheri Khan Taraki site initially found "distinctive hand-made ceramic vessels decorated with a combination of geometric and zoomorphic motifs" representing the earliest cultural phase, while a later discovery of ceramic vessels with "distinctive polychrome decoration" in sites in Lewan of the overarching Bannu region citing these findings as hailing from the Sheri Khan Tarakai Phase.

[2] [4] The civilization at Sheri Khan Tarakai was understood by researchers as a peoples who heavily relied on ceramics as opposed to metals and who grew grains– particularly wheat and barley– while herding sheep, goats and cattle.

This division of the excavation sites into distinct phases has also been underscored by discoveries of similar ceramic material used to make pottery, lithics, and terracotta figures in surrounding areas of Girdai, Her Khala Sheri, Lewan, and Islam Chowki.

[2] The Akra and Ter Kala Deri sites of the Bannu Archeological Project saw the discovery of advanced pottery of a unique ceramic element (as compared to surrounding regions) along with low standing mound structures and relatively intact stratified deposits; this coincided with the discovery of iron tools and etched beads with no traces of teracotta figures or coins– both of which were found in other sites of the Bannu Archeological Project.

[2] Employing absolute and relative dating techniques, researchers involved with the Bannu Archeological Project have been able to illustrate a general sense of chronology.
