That depends on your definition of “dinosaur” and “man”.  What’s the historical time period you are thinking of?  And what definition of “dinosaur” do you mean?

I’m not certain what the “time periods” you’re referring to are, can you clarify?  Also what do you mean by “dinosaur” and “man”, as compared to “human”?
