While megalodon sharks were indeed prehistoric giants, their shape may have differed from modern sharks, according to a new study.
Otodus megaladon hunted in the world’s oceans 15 to 3.6 million years ago. So far, they are known only by some vertebrae and enormous teeth, which resemble the smaller teeth found in modern great white sharks. Scientists have conjectured that the megalodon was 65 feet long, even though no complete skeleton has ever been found.
