How much older are sharks than dinosaurs?

Can dinosaurs come back?
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.
