Highlights



A submerged, 12 m long monolith has been discovered at a water depth of 40 m, in a shallow bank of the Sicilian Channel.


Morphological evidence, underwater observations, and results of petrographic analysis testify that the monolith is man-made.


This monolith suggests a significant human activity in the Pantelleria Vecchia Bank, a former island of the Sicilian Channel.


Seawater inundated the Pantelleria Vecchia Bank at 9350 ± 200 yr B.P., presumably forcing inhabitants to migrate.
