I thought crocadiles and gators and most reptiles other than the aforementioned species of birds are also descendant of the dinosaurs. Is that accurate or did NASA invent that myth too? Which birds are thought to be descendants of the dino's? I heard that recent discoveries make some folk think that dino's had feathers. A T-rex with feathers sounds like a silly beast to me, but, I don't think I'd laugh at 'em to their faces. Any experts out there know the current "facts" on these matters?
