Controversy has surrounded the timetable of existence for megalodon, the world's largest ever shark, but a new study concludes that this 60-foot-long predator became extinct 2.6 million years ago.
The study, published in the latest issue of the journal PLOS ONE, counters other theories that megalodon (

"I was drawn to the study of
extinction because it is fundamental to know when species became extinct to then begin to understand the causes and consequences of such an event," explained lead author Catalina Pimiento.
