How Megalodon possibly looked like

@Apex Titan
Another singular fact: since they have existed, more than 400 millions years, shark have always been among the most serious competitors of the marine life, but, except, by reading you, the Megalodon period, never the most performing ones. During the Paleozoic era, some cartilaginous fishs like dunkleosteus ruled, during the mesozoic era marine reptiles were the dominant predators (itchyosaurus, pliosaurus, plesiosaurus and above all mosasaurus during the Cretaceous period). We know, during the Cretaceous period, that some sharks bigger than the extant white sharks, for example the Cretoxyrhina . https://en.wikipedia.org/wiki/Cretoxyrhina https://www.sharks-world.com/prehistoric_sharks/ https://www.nhm.ac.uk/discover/shark-evo...eline.html What I just want to say: prehistoric marine life has always been abundant, prolific. The sharks have always been a success of the evolution: they survived through 5 main extinctions even if we consider that the biggest shark of the Cretaceous ocean disappeared with the marine reptiles 65 millions years ago. Just after, sharks regained lost ground. In short, sharks have never been alone under the sea, it's difficult to believe, that suddendly, a monstruous shark, the megalodon, dominated so intensively. They coudn't be alone, I am just persuaded about that. |
