I get it, I just knew there was a Japanese firm i thought that said it had greater than 90% of DNA for a herbivore specials of dinosaur, they found a super intact skeleton with skin etc on it. They were saying they could bring it back if they had a surrogate large enough
DNA can survive in 'sub-fossils' for a few thousand years, like buried human skeletons. It can survive for a few tens of thousands of years in exceptional scenarios, such as inside permafrost. Even then, DNA can be partially broken down, and contaminated with other organisms' DNA, especially that from germs.
This material can tell you how closely related a mastodon is to an african elephant, or whether your bronze age ancestors had caught the herpes virus, but it can't currently be used to clone long dead creatures.
The last non-avian dinosaurs are over 60 million years old, and practically none of the material they have left behind is 'organic'. Think more like impressions in rocks, bone that has partially or completely turned into rock, etc.
