What is the importance of oracle bones?

Answer 1

Oracle bones was used by priests to tell the future. The Shang priest would interpret crack(produced on bones by applying heat) as giving answers to questions about the future. The questions and their answers are carved onto bones. Such bones were usually the shoulder bones of sheep or cows occasionally turtle shells. The bones were also used to record names of rulers, family histories and events such as the eclipses of the sun and moon.
