Can dinosaurs be resurrected?

Dinosaur extinction: Dinosaurs suddenly disappeared at the end of the Baiping period 65 million years ago, which became a mystery in the evolutionary history of life on earth. This mystery has not been solved so far. In the past, all living things on the earth were recorded in fossils. Many dinosaur fossils have been found in Mesozoic strata. A large number of bones or various shapes can be seen in it. However, in the subsequent Cenozoic strata, no fossils of non-bird dinosaurs were found at all, so it is inferred that non-bird dinosaurs became extinct in Mesozoic.

Unable to clone: scientists need DNA to clone dinosaurs, but DNA will start to decompose after the death of organisms. This is the result of enzymes (from soil microorganisms, somatic cells and gastrointestinal cells). Ultraviolet radiation also breaks down DNA. In addition, oxygen and water can also change the chemical properties of DNA and break the double helix chain. It will break down DNA into smaller and finer fragments until there is nothing left. If you can't extract DNA, you can't clone dinosaurs.
