Can we clone extinct dinosaurs from DNA preserved in their fossils?

Paleontologists and molecular biologists have searched for a couple of decades to find and replicate DNA from some non-avian dinosaur fossil. But to date, no results have been obtained, either from fossil bones or teeth preserved in sediments or from a fossil preserved in amber, as was done in the film, Jurassic Park. To successfully isolate DNA from a long-extinct dinosaur, let alone clone one, scientists would have to overcome numerous serious challenges, including contamination and deterioration of the original DNA.

Despite all of what you see in movies and science fiction, and some of its very entertaining, and you know some nice ideas in there, tantalizing ideas, we cannot clone a dinosaur. We cannot create a Jurassic Park. For a number of reasons first there isn't a lot of DNA preserved in the ancient fossils, and that that is, is severely damaged. We're nowhere near ever finding a whole genome for an extinct dinosaur. Maybe in a few years, maybe down the line, we might finally get some really reliable evidence on a DNA sequence from a dinosaur, from some tissue of an ancient dinosaur, but it will only be a tiny, tiny smattering of that huge genome. It could be as many as thirty thousand genes, and we might get a signal from a couple of them, and that certainly won't be enough to clone a dinosaur. So I think the answer to this question is it's impossible to clone a dinosaur.
