Megalodon is an incredible, powerful animal, an incredible part of the history of our planet - but it is a current history. The new discovery means that we are still discovering its way of life, life cycle, and evolution. It disappears because it means that environmental changes and competition can not capture enough food to maintain itself. We should listen to the plight of other creatures swimming in it now and not as a myth to fantasize time on huge teeth and help to protect them before it is too late .
A huge shark that died millions of years ago is the biggest shark in history, one of the biggest fish in history. Scientific name Carcharocles megalodon means 'big teeth'. There is a good reason for that. That big tooth provides scientists with important clues about how this creature looks and when it will die. In 2014, the research team at the University of Zurich examined the huge shark fossils using a method called optimal linear estimation to judge the age. Their research published in PLOS ONE magazine discovered that most fossils date from Miocene to Pliocene (15.9 million to 2.6 million years ago). The author wrote that all signs of the existence of this creature ended with the current fossil record of 2.6 million years ago. By contrast, according to the University of California Department of Paleontology Museum, our early homo sapiens ancestry appeared in the Pleistocene era only 2.5 million years ago.
Megalodon (Carcharocles megalodon) means "big teeth" and it is an extinct shark species that inhabited about 23 to 2.6 million years ago (mya) from the early Miocene to the late Pliocene period. It was previously thought to belong to the family Lamnidae and was closely related to the white shark (Carcharodon carcharias). But it is believed to be a unanimous and extinct possibly families Otodontidae, and it was different from the early Cretaceous early white sharks. The type of placement is still controversial and the author has placed it in Carcharocles, Megaselachus, Otodus or Procarcharodon.
It may be a pop culture, a cable model and a nickname for a movie rated B, but Megalodon is half the name of this shark science. Most paleontologists classify prehistoric predators as extinct Carcharocles (or less commonly known Otodus) and others belong to the genus Carcharodon (its only surviving member is Dabai) I believe. Or Carcharodon megalodon. In both cases, Megalodon is not a common name but a species name (it seems to be the difference between a human and a wise man).
