Archaeologists say a shipwreck off Kekova Island in southern Turkey is the oldest ever found, BBC News and CNN reported.

They have dated it to between 4,400 and 4,700 years ago, in the Early Bronze Age, both outlets reported. That is around the time Egypt's Great Pyramid was being built, BBC News reported.

The ship's wood has not survived, BBC News reported. But divers found more than 30 clay storage jars, called amphorae, and three large stone anchors on a slope about 30 meters, or 100 feet, under the sea.

Because no wood was left, the team could not use radiocarbon dating, BBC News reported. Instead, they compared the shape of the jars with ones found in Egypt and the Middle East that are known to be that old.

"We can definitely say our wreck is Early Bronze Age. This is 100%," Hakan Öniz of Akdeniz University, who led the dig, told the BBC. He told CNN the team is "generally confident" it is the oldest shipwreck in the world.

Some jars still hold a glossy residue, BBC News reported. "I looked inside and nearly fainted," said Karin Sowada, an archaeologist at Macquarie University in Australia. She said it could be olive oil, wine or tree resin.

One jar has a set of marks and two holes, CNN reported, citing Turkey's culture ministry. It may have been used to make cheese or butter, which could mean sailors kept goats on board.

Clay tests suggest the jars were made in the Jordan Valley, Turkey's culture minister said in a statement, CNN reported. The ship may have been sailing from the eastern Mediterranean coast to Troy or Crete.

The wreck was first found four years ago, Öniz told CNN. The previous record holder was a wreck off Greece's Dokos island, about 4,200 years old, BBC News reported.

The finds will go on display in a new underwater archaeology museum in Antalya, BBC News reported.

What we know: The team dates the wreck to 4,400 to 4,700 years ago based on its jars.
What we don't: What the jars carried, and where exactly the ship was headed.
