Why Would Megalodon Go Extinct?

Discovery.com – The 60-foot-long Megalodon, the world’s largest known shark, died out 1.5 million years ago…or did it?
Some scientists think the monster shark is still among us, and unusual sightings have been claimed for many years.
The British survey ship HMS Challenger, while dredging a seabed near Tahiti in 1875, pulled up a pair of Megalodon teeth, one of which is shown here.
Over the years, dating of the teeth has produced mixed results.
Some dates fall in the 10,000-15,000-year-old range. That’s a far cry from 1.5 million years ago, when Megalodon supposedly went extinct.
It remains unclear how Carcharodon megalodon went extinct, if it did.
The supposed extinction of the huge shark, whose jaw and teeth have been reconstructed at the North Carolina Museum of Natural Sciences, remains a mystery.
Did oceanic cooling and sea level drops do it in? Was there a decline in its food supply? Was it out-competed by new species?
Or could it still be alive? Questions remain.
