Carthaginians had ocean going ships that carried hundred of people that made settlements on the Gold Coast of Africa. After Carthage fell to the Romans, for hundreds of years the Roman emperors personally scoured the city searching for the hundreds of tons of gold that the Carthaginians were known to have as they paid tribute to Rome every year in tons of gold. I bet a Rio that gold is in Brazil.
At the naval battle east of Carthage, some ships were known by the Romans to have fled west, escaping from Carthage with the Carthaginian Elders and others on board.
