Archaeologists believe they've found the oldest known tool used for grinding or scraping, we’re talking some 350,000 years ago.
Found in the Tabun Cave in northern Israel, the rock tools are a type of small rounded stones, and is much older than homo sapiens by at least 50,000 years.
Previously, such tools weren't thought to have been introduced until much later, approximately 200,000 years ago.
The dolemite cobble, seen here from different angles, bears markings similar to those found on later grinding tools. Grinding and scraping require a horizontal motion and allows for more delicate work
