Why are dinosaurs a powerful tool in the move to discredit evolution?

Dinosaurs are actually a great way of PROVING evolution. The fossil record has shown many evolutionary pathways dinosaurs ventured down during their 165 million year reign. Fossil evidence has shown many species of theropods, or meat eating dinosaurs, had feathers and increasingly bird-like characteristics. New discoveries in China have furthered the link between dinosaur and bird, helping to prove that evolution isn't merely a theory, but is indeed a irrefutable FACT.
