Scapulimancy is the correct term if ox scapulae were used for the divination; plastromancy if turtle plastrons were used . </P> <P> Diviners would submit questions to deities regarding future weather, crop planting, the fortunes of members of the royal family, military endeavors, and other similar topics . These questions were carved onto the bone or shell in oracle bone script using a sharp tool . Intense heat was then applied with a metal rod until the bone or shell cracked due to thermal expansion . The diviner would then interpret the pattern of cracks and write the prognostication upon the piece as well . By the Zhou dynasty, cinnabar ink and brush had become the preferred writing method, resulting in fewer carved inscriptions and often blank oracle bones being unearthed . </P> <P> The oracle bones bear the earliest known significant corpus of ancient Chinese writing and contain important historical information such as the complete royal genealogy of the Shang dynasty . When they were discovered and deciphered in the early twentieth century, these records confirmed the existence of the Shang, which some scholars had until then doubted . </P>
