I was wondering if any of the professional paleontologist's here could offer any insight on this question: Is it possible that at least one species of dinosaur had developed a more advanced civilization similar to our pre-industrial civilizations? Could any evidence have survived both the impact and resulting global catastrophe as well as 65 million years? What do we produce today that could survive a similar incident and 65 million years to provide proof of our existence in the future if we go extinct? Thank you for your insights.
