A superficial interpretation would speak of remorse and the search for redemption. South China Morning Post/South China Morning Post via Getty Images After making substantive adjustments to the data and reanalysing it, the team concluded that the megalodon would have been killed off 1m years before the supernova event. With enough mammoth DNA, Church explained, a Crispr-edited Asian elephant would become something else entirely: a modern hybrid that looked and behaved like a mammoth but shared DNA with a living species. "With the reintroduction of the woolly mammoth we believe our work will restore this degraded ecosystem to a richer one, similar to the tundra that existed as recently as 10,000 years ago," the company says. That said, its not impossible to imagine what it might be like if we could train these extinct creatures. Even then, it would still be highly unlikely for humans and dinosaurs to live together in any meaningful way due to the vast differences in their physiology and behavior. Scientists have also found evidence that suggests that large sauropods such as Diplodocus may have been relatiely docile. bring back the megalodon The Megalodon It is impossible to bring dinosaurs back because the DNA that is necessary to clone them has degraded over time.

They roamed the earth for over 100,000 years before going extinct around 10,000 years ago. Also, their social structure means that they live in large herds, which makes them difficult to contain. Its long tail contained four large spikes on its back, which were likly used for defense. The last known specimen died in a zoo in Tasmania in 1936 due to neglect. Scientists can now reveal the size of the rest of the megalodon's body, including its huge fins. Rather, it is possible that there was a period of faunal turnover [many species becoming extinct and many new species appearing] rather than a true immediate and catastrophic extinction caused by an astronomical cataclysm like a supernova, said Robert Boessenecker of the University of Wisconsin, who led the team.
