that's the kind of news I expect to be in mice and not in humans ;)
Next, dinosaurs.
Dinos are a few orders of magnitude harder. No DNA or RNA fragment can even remotely survive over 65M years. To make something similar to a dino researchers will have to produce a working mix of bird and reptilian DNA - which is enormously complicated.
Plenty of avian dinosaurs around. Just not the ones you're thinking about.
