A well-preserved 4,500-year-old skeleton of a man was found on a beach south of Rome, Italian police told Reuters.
The man is believed to be a warrior killed by an arrow in the chest, Reuters reported.
Six small vases were also found buried near the man.
"We thought it was that of a Roman solider, but then the experts identified it as dating back to the third millennium B.C.," said Raffaele Mancino, an official who oversees Italy's cultural heritage.
The skeleton was discovered during a routine air patrol of areas of archaeological interest.
