It is the largest shark ever to have lived, weighing 50 tonnes and measuring 18 feet long.However, swimmers can breathe a sigh of relief - the megalodon really did become extinct 2.6 millions years ago.Recently it was claimed the shark could still exist - forcing researchers into pinpointing its exact date of demise. Researchers from University of Florida and the University of Zurich hope the study appearing online today in the journal PLOS ONE showing the species became extinct 2.6 million years ago will clarify public confusion. The study may also one day help scientists better understand the potential widespread effects of losing the planet's top predators, said lead author Catalina Pimiento.
