Were there cavemen back when dinosaurs where alive?

there was no such thing as a cave man. Men didn't live in caves. It was unsafe, unhygienic, and an all around bad idea. Based on the findings that we have to work from at this point in time I would have to say no but that's not to say that they didn't. Maybe we just haven't found the remains of a person that lived during that period. So i can't say safely yes or no. But like I said with what we know at this point in time I would have to say the findings do not support human existence during the period of time you're asking about.
