Carcharodon (Megalodon)

General Background
Their are a Species of a Genus called Carcharodon,the same Genus with the smaller and less stocky Great White Shark.This Species was the top predator of the Miocene and among the top predators in the Pliocene.They grew up to 59 feet long and weighed a staggering 65 tons.These sharks have effected the oceans on evolutionary level.Dolphins live in groups because it was the only way to survive a Megalodon attack.Great White Sharks stay close to the shoreline because back then if they went out to open sea they would get eaten by Megalodons.Megalodons' in the Miocene had one predator,each other.The Pliocene was different though,Their predators then were each other of course but also Livyatan.This and the change of climate and of prey leaving the warm seas may have lead to Megalodon's demise.
