Burial No. 1, Northeast Mindanao Salvage Project, April 4–6, 1981. Archaeologist Warren Peterson and his team excavated six graves in the site called Masago near present-day Butuan City in 1981. The first burial contained the skeletal remains of a young individual of unknown gender lying on its back with arms crossed on the chest. The weight of a large earthenware jar on the lower legs had depressed the leg bones by several centimeters. This photograph shows the jar elevated on a block of soil for analysis. Near the burial, Chinese ceramic sherds of the Northern Song period from kilns in Fujian or Zhejiang suggest that the grave dates to the tenth to twelfth century.
