Oddly enough I agree with Falconer on this. Time will not let you change things. Something will happen to change things, or at least even things out.

So, you have the basic question, What would happen if you went back in time and killed your grandfather? Would you disappear? Would your parents disappear but you just stay there? Thus a paradox is created?
Really you would not be able to do it. Somehow you will be stopped. (the same for the other killings)
But as Falconer posted, you will return and never had been around. Think "Its a Wonderful Life." type thing.

Then there is what if you killed someone from a very longtime ago in the past, would a whole load of people disappear from the world today, all their descendants? Because without that person, all those people would not exist...

Also, could you go back in time and bring back a dinosaur egg?
I would say no. Even if you can get it, and return it and hatch it. The creature would die quickly with its system not being ready for the diseases of our time. And the same can be said for the person getting the egg. (come to think of it, same can be said for the above and below as well.)

Also, going back in time and killing (sorry for the repetitive "Killing" thing, but...) Hitler, how would that change the world? would someone worse have taken his place?
That will depend on when you did it. But I think Germany after being left in the wake of WWI, would have done the same. He was influenced by a number of things, and had a number of followers with his same ideas. I think things would have been about the same.

And finnaly, what if you went back in time and told people about something like something about dragons for example and make them believe that dragons were god or something similar, you could easily make them worship something. My younger brother sadi to go back in time with a group of people, all dresses in werewolf costumes and run through the streets of some old city, then tell the terrified people to worship you, lol
You would end up coming back to the present day and find statues of werewolves everywhere!
This would not have worked. Something like that may have had a short lived following but the stronger religions would have crushed it in time.
But I must say my influence on this are the Dragonlance novels. They have had a couple of stories of time travel (with magic) and has major events remain unchanged.
