How did Sharks survive the dinosaur extinction?

They even managed to survive during times when the ocean lost its oxygen – including one such event in the Cretaceous period, when many other, larger, species died out. As a refuge, sharks moved deeper underwater, says Bird. And while there, they had another cunning trick. Some evolved the ability to glow in the dark.

While dinosaur bones can survive for millions of years, dinosaur DNA almost certainly does not. But some scientists continue to search for it – just in case. So it looks like cloning a dinosaur is off the table, but an alternate way to recreate the extinct animals would be to reverse-engineer one.
