Megalodon and Modern Sharks
Dr Anjani Ganase discusses recent research and findings about sharks . MEGALODON THE SUPER PREDATOR The megalodon (Big Tooth) sharks were massive predators that roamed the oceans for over 13 million years until they went extinct three million years ago. During that time, megalodons could grow to 15 m in length. The closest rivals were the great white sharks that overlapped with the megalodons for about 400,000 years but were dwarfs - 5m - in comparison. From the size of the skeleton and teeth - one tooth is the size of a hand - the megalodon was a major predator on the high seas feeding on large fish, whales, and even other sharks. Scientists found a fossilized whale bone with markings and pieces of megalodon teeth in it. Recently scientists were able to chemically confirm that megalodons were on the very top of the ocean food chain, capable of feeding on whatever, whenever it wanted. Through nitrogen found in the teeth of a megalodon species - Otodus megalodon ...
