Some of the intricate shapes and designs of Final Neolithic pottery at Gebel Ramlah differ greatly from even Late Neolithic productions of the region just before. In fact, pieces like the ripple-decorated caliciform beakers most closely resemble Nubian pottery. Gatto hypothesizes that, perhaps, individuals from farther out in the Nubian Nile valley were moving toward Gebel Ramlah and surrounding regions (where water sources were slightly more reliable) as water dwindled during the Final Neolithic.
