Two missing species of shark were discovered in a new analysis of weapons made from shark teeth and used by 19th century islanders.
Over 2,400 shark teeth have been recovered from a passenger by Custom officials at the Indira Gandhi International airport.
The dense, flat and crushing teeth of sharks contain fluoride keeping that is an active component of most toothpastes and dental care mouthwashes.
