No they existed well before humans ever did 5-20 million years ago in the miocene & pliocene periods. They were up to 75 foot long with a mouth 12 foot wide 10 foot high the dorsal stood aprox 8 foot high and the tail fin aprox 20 foot top to bottom. They feed on whales & other sharks.
If Carcharodon megalodon does still exist, which is unlikely, they are rare. In the case that they came across a human, they wouldn't actively hunt it. Like other sharks, they would only bite a human out of curiosity or misidentification. All in all, they would not pose much of a threat, and definitely not more than that of any other shark.
no because it was extinct with the dinosaurs
meglodon sharks might have existed back in prehistoric times
There is evidence suspecting that the megalodon still exist & there is evidence suspecting it does not. Some scientist believe there is absolutely NO way it still exist, and some disagree. People keep talking about how they died out 1.5 million years ago, but they have fossils of teeth from 13'000 years ago. It IS possible that they are still out there, but no one knows for sure.
Megalodon does still exist.
no their actually very much alike the whale shark being a filter feeder so their very gentle
Megalodon did exist. Their teeth were commonly found fossils for hundreds of years before it was discovered that they were actually the teeth of a giant shark. Before that, they thought that the teeth were the petrified tongues of dragons! Megalodon were sharks, that may have been up to 50 feet long, and who commonly hunted whales. They existed between 25 and 1.5 million years ago.
yes
Because of greed.
This is a controversial question. Do any of us really exist? We can never know, but our existences in this reality, though it may not be the purest reality, is certainly evident since we are able to communicate. Now, for the megalodon. It is a topic of scientific debate. No one can know for sure if the megalodon existed or exists, because there is unclear and inconstent evidence for it. It may have existed, and could still exist in deep pockets of the ocean known as trenches where humans are unable to observe marine life.
No the Megaladon shark is extinct and good thing too because, it was on of the largest sharks ever. But there is a very small chance that it lives on the near ocean bottom feeding on giant squid.
No. They were a native American people. Many decemdents of Aztecs are still alive.
