An official at the agency overseeing Cambodia's famous Angkor Wat temple complex says tests have confirmed that a wooden boat found buried in a dry riverbed is from the early 13th century.

Apsara Authority spokesman Long Kosal said Monday that tests by a research institute in New Zealand confirmed the age of the 12.8-meter (42-foot) -long boat, which was carved from a single tree trunk. He said it is the oldest boat ever found in Cambodia.

A farmer discovered the boat in April while digging mud from the riverbed, several kilometers (miles) from the temple complex. The boat was sunk in a pond in front of the temple to keep it preserved pending restoration.
