12-meter-long man made monolith discovered off Italian coast [View all]
A massive monolith over 10,000 years old has been found in the Mediterranean Sea near Italy, scientists say. The block, which was apparently constructed by humans, bears traces of prehistoric civilization.
The 12-meter-long monolith resting on the sea-floor was located at a depth of 40 meters, in a shallow bank of the Sicilian Channel, says the report by ocean scientists from Italy and Israel published in July.
It is broken into two parts, and has three regular holes: one at its end which passes through from part to part, the others in two of its sides.
According to the study, the site was abandoned at about 9,350 ± 200 years BP (Before Present) and the morphological evidence, underwater observations and results of petrographic analysis suggest that the monolith was made by humans.
This discovery provides evidence for a significant Mesolithic human activity in the Sicilian Channel region.
The scientists say the block was cut and extracted as a single stone from the outer rectilinear ridge which was about 300 meters to the south, and then transported and possibly erected.
From the size of the monolith, we may presume that it weighs about 15 tons, the study says, adding that its function hasnt been specified yet.
