The video discusses the megalodon, a prehistoric shark that could grow over 18 meters long, with teeth measuring up to 17.8 centimeters. It went extinct around 2.6 million years ago.

The presence of ion 60 isotopes in prehistoric seabed deposits supports this theory. These isotopes, along with muons, could have caused mutations and cancer in marine life, with the megalodon's large size and shallow water habitat making it particularly vulnerable.
