Why did the Megalodon become extinct? Scientists from Zurich University have proposed the largest shark that ever lived became extinct due to a lack of prey and increased competition from predators. Carcharocles megalodon lived between 2.6m and 28m years ago and could grow to up to 18 metres in length. It weighed up to 100 tonnes and fed on small whales.
Could the Megalodon still exist? There is no record, they completely vanish. The only valid conclusion is megalodon became extinct. This shows the evolution of the megalodon, from a small Cretaceous shark to the apex predator of the Pliocene. After the Pliocene, megalodon fossils are no longer present.

why do scientists think dinosaurs became extinct?
Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth’s climate that happened over millions of years.
