On Nov. 21, the archeological team from the State Administration of Cultural Heritage discovered two ostrich eggshells with stone-drilled holes that date back 20,000 years ago at the Xuchang primitive ruins.
Experts from the team said that the two ostrich eggshells were the earliest artificially stone-drilled specimens that were ever found in Henan Province and the best-preserved specimens found in China over the age of 10,000 years, which showed that the primitive craftsmanship had developed to a quite high level even at that time.
