Researchers are learning more about ancient central European society thanks to stones from thousands of years ago.
A team of international scientists analyzed markings made on more than 400 stone plaquettes that date back 15,800 years, and uncovered something not previously known during the final period of the Stone Age. The stones were etched with depictions of ancient fishing practices that had not been recorded in the Upper Paleolithic era, revealing that people used nets to catch fish.
