20,000 years old drilled specimen found

The archeological team from the State Administration of Cultural Heritage discovered two ostrich eggshells dating 20,000 years old with stone-drilled holes at the Xuchang primitive ruins.

These two ostrich eggshells would be the earliest artificially stone-drilled specimens ever found and the best preserved specimens found in China over the age of 10,000 years. These shells show that the primitive craftsmanship had developed to a quite high level even at that time.
