He and his colleagues have hypothesized that megalodon went extinct as a result of great white sharks. There is debate among the scientific community about what factors caused the megalodon to go extinct.įor some scientists such as Boessenecker, the answer could be relatively simple. What happened to the planet's biggest sharks? He said paleontologists have "no idea" how fast the extinction took place, but that even the timeframe mentioned above could be considered rapid in geological terms. "Right now we have the extinction date pinned down to an 800,000 year period, between 4 and 3.2 million years ago, with the highest likelihood of going extinct about 3.5 million years ago," Robert Boessenecker, of the College of Charleston's Geology and Environmental Geosciences Department, told Newsweek. The species was found across Earth's oceans, except in the polar regions, and it would feed on whales, seals, turtles and other sharks.īut then, in less than one million years, it disappeared. Megalodon first appear in the fossil record around 20 million years ago, having descended from a lineage that appeared about 60 million years ago.
