Archaeologists have unearthed remnants of what they believe is a 1,000-year-old village on a jungle-covered mountaintop in the Philippines with limestone coffins of a type never before found in this Southeast Asian nation, officials said on Thursday.

National Museum official Eusebio Dizon said the village on Mount Kamhantik, near Mulanay Town in Quezon Province, could be at least 1,000 years old based on US carbon dating tests done on a human tooth found in one of 15 limestone graves he and other archaeologists have dug out since last year.
