Scientists have found very old tools made from whale bones. The tools are about 20,000 years old. They were found near Spain and France, in a place called the Bay of Biscay. The bones came from big whales like blue whales, fin whales, and sperm whales. The people who made these tools did not hunt the whales. They probably found the bones from dead whales on the beach. The tools were long and thin, like spears. People used them to hunt big animals like reindeer and bison.

This discovery is important because it helps people understand how people lived a long time ago. The study was published in a science magazine called Nature Communications. Many old things have been lost because the sea has risen, so this discovery is special. New technology helped scientists know how old the tools are. A researcher named Jean-Marc Petillon said whale bones were good for making strong tools. Another expert, Vicki Szabo, said the discovery shows that people and whales have a long history together. The study also shows that people who lived near the coast fished, hunted, and used the sea to survive.
