Where did the dinosaurs go in the Bible?

So we, or I, know about how the Earth was created in seven days and then man came, and etc. But i'm confused. Where were all the dinosaurs in all this? I mean we have the bones to prove that they were here, and then we have all the ancient religions that proves that God (or some higher being..) was/is here. I'm a Christian, so, I believe in God but I'm not a die-hard Christian. I believe that other people's god(s) are basically the same as mine, so, feel free to enlighten me on this. Your theories are appreciated!
