Why don't they create a machine to create dinosaurs with there dinosaur bones I mean after all they have the dinosaurs DNA with there dinosaur bones so why can't they that's my theory From:Juan herrera Dinosaurs
The dinosaur bones we dig up are fossilized. They are not actually dinosaur bones. The bones from a dead dinosaur get buried, and over a long, long time the organic material is dissolved, being replaced by minerals. There is no actual dinosaur material left, thus there is no DNA either. Permineralization
No DNA has been found that's more than one million years old. The dinosaurs became extinct (roughly) fifty million years ago. It's very unlikely that we'll ever discover dinosaur DNA. As Dave explained, the objects which we call "dinosaur bones" are not actual tissue from dead dinosaurs. They are fossils in which the more massive organic material has very slowly been replaced with inorganic material (the same as rocks), but the process occurred so incredibly slowly that the anatomy of the dead animals (or plants) has been conserved. Bones are quite massive, so they are often preserved as fossils, with the organic material replaced by inorganic. But DNA is too fragile and is never fossilized, except in organisms that died much more recently than dinosaurs.
Fifteen to twenty years ago several studies claimed retrieval of DNA from increasingly ancient remains, including a Cretaceous dinosaur. Subsequent work has led to the conclusion that in each instance there was contamination of the samples.
Amazingly it seems no-one else here is aware of the.... well, just type e.g. "dinosaur soft tissue" into a StartPage (or Google if privacy is no concern) search bar.
Maybe in the future we will be able to do it, right now its impossible as all the bones are fossilized and dont really have Dna material in them.
Yes afaik that's the case. That any tissue, soft or not, has survived for maybe 100 my+ is extraordinary, just the same.
