Shark Tooth Weaponry and Historical Insights

The video explores how Field Museum biologists and anthropologists use shark-tooth weaponry to study the historical distribution of Central Pacific sharks. The anthropology collection includes weapons from Kiribati, featuring teeth from eight shark species, two of which are no longer found locally. The video discusses potential reasons for this change, such as trade, overfishing, and climate change. It highlights the importance of museum collections in providing unexpected insights and details the variety and construction of shark-tooth weapons and defense mechanisms.
