A study by Western Australia's Murdoch University concluded that DNA cannot survive more than 6.8 million years—a finding that effectively rules out the tantalising prospect of replicating dinosaurs. Most dinosaurs died out about 65 million years ago.
"We've been permanently plagued by this Jurassic Park myth that's been kicking around since the early nineties," lead researcher Mike Bunce told the Sydney Morning Herald.
"The myth is still out there. Even other scientists ask whether it is possible."
