Researchers found old clay jars under the sea near Kekova island in Antalya, Turkey. The jars are around 4,400–4,700 years old. They may come from the world's oldest lost ship.
The jars probably came from the Jordan Valley. People may have used them to carry oil from olives or wine. Researchers found similar jars in Egypt, Troy and Crete. These finds suggest that people in these places traded with each other.
One jar has two holes and nine marks. Sailors may have used it to make cheese or butter. They may have taken goats on long sea trips and used their milk for food. The jars offer clues about both trade and life on ships long ago.
