A group of Chinese and Turkish evangelical explorers said on Monday they believe they may have found Noah's Ark - 4000m up a mountain in Turkey.

The team say they recovered wooden specimens from a structure on Mount Ararat in eastern Turkey that carbon dating proved was 4800 years old, around the same time the ark is said to have been afloat.

"It's not 100 per cent that it is Noah's Ark but we think it is 99.9 per cent that this is it," said Yeung Wing-cheung, a Hong Kong documentary filmmaker and member of the 15-strong team from Noah's Ark Ministries International.

The structure had several compartments, some with wooden beams, which were believed to house animals, he said.

The group of evangelical archaeologists ruled out an established human settlement on the grounds that one had never been found above 3500m in the vicinity, Yeung said.
