Excavations on the Indonesian island of Sulawesi have uncovered two unique and deadly artefacts dating back some 7,000 years – tiger shark teeth that were used as blades.
These finds, reported in the journal Antiquity, are some of the earliest archaeological evidence globally for the use of shark teeth in composite weapons – weapons made with multiple parts. Until now, the oldest such shark-tooth blades found were less than 5,000 years old.
