I love thinking about things like this, but we will never know! Sometimes I close my eyes and imagine I traveled back in time to the days of the Dinosaurs and just observed how the world was back then. But I wonder if I'd be able to survive. The atmosphere, environment, microbes, etc, would be drastically different from what we've evolved to handle. Millions of years ago is a very long time! Edit: Apparently microbes from millions of years ago would be so evolutionary distant that they might not regard me as host.
