Question: Are we able to bring back Dinosaurs?

Liam Herringshaw answered on 9 Dec 2025:

The simple answer is ‘no’. We’d need dinosaur DNA, and fossilized DNA only goes back a few tens of thousands of years. We don’t have any DNA fossilized from the Cretaceous, Jurassic or Triassic periods, when dinosaurs roamed the Earth. HOWEVER, the alternative answer is ‘we don’t need to, as they’re still alive.’ Over the last 30 years or so, exceptionally preserved fossils, along with advances in genetic and chemical science, have led scientists to conclude that birds are part of the theropod dinosaur group. Most of the famous types of dinosaurs became extinct 66 million years ago, but a small group of feathered, flying dinosaurs survived. So when you see a robin or a herring gull or a buzzard, you can shout “DINOSAUR!”
