Eggshells: A New Form of Communication

According to researchers, a recently collected cache of ostrich eggshells were used as symbolic methods of communication among African hunter-gathers 60,000 years ago. These shells have been collected over a period of the last few years at Diepkloof Rock Station in South Africa by the University of Bordeaux. Two hundred and seventy in all, this is a large enough sample to demonstrate that Stone Age people created design traditions. Some of these eggshells also have holes in them, demonstrating that they were used as canteens.
