I've heard something like that before, and apparently so did the writers from ST: Voyager. Dinosaurs evolving during all that time to develop space travel, then leaving Earth while erasing all knowledge of their advanced culture. Apparently some forms of dinosaur, if they continued to evolve, would look a little like those classic aliens with bald heads and big eyes. Though supposedly they'd have a tiny little tail as well.  

As I said just before, 5 million years is a long time

Heh. Anyway, My friend had this theory long before Voyager came out. But it's probably written in a book somwhere...
