Would it really be possible to get the DNA of dinosaurs and then recreate them?

The ABCs of DNA

DNA stands for deoxyribonucleic acid

  • It is found in every cell of every organism on Earth, including dinosaurs
  • Your DNA determines many characteristics that define you, like the color of your eyes, hair, etc.

Imagine for a moment…

Researchers came up with fragments of dinosaur DNA, but could not make a complete dinosaur

  • They would have to combine the fragments with the DNA of a modern-day animal to create a living organism
  • The creature would not be an actual dinosaur, but a hybrid

Is DNA in the fossils?

Dinosaur fossils are all that’s left of these prehistoric animals

  • Immersed for tens of millions of years in ancient mud, minerals and water, the fossils come from the dinosaur’s so-called “hard parts” – its bones, teeth, and skull
  • With enough fossils, scientists can build a dinosaur skeleton

The trouble with ‘dino-DNA’

DNA deteriorates and disintegrates after about 7 million years.

  • It is not possible to make a dinosaur from its DNA, even with the best technology available today
  • Although it’s too late to find dinosaur-DNA in woolly mammoths, scientists recently found it in the fossil of Neanderthals and other ancient mammals.
