The only thing that makes sense to me is that when you travel in time, the time line branches off at that event. The original universe is unchanged but there's basically another dimension that forms at the event of time travel. So paradoxes such as "if you go back in time to kill yourself, etc" are not an issue. It also means you can't change the past. If you change the past and then go "back" into the future you're just going to the future in the universe that was created by your action. The original universe and all the people in it go merrily on their way.
Stephen Baxter does a good job of explaining this in "Time Ships" [but I did have these ideas before I read Stephen Baxter and I have at least 1 witness, he was just the first author I read that dealt wit time travel in a way I approved of]

Are they actually going back 85 million years in Earth history? Does anyone know if they consider any time travel ramifications for that? For example, if you pump up some petroleum 85 million years ago, then that petroleum isn't available for your ancestors in the future. Deforesting areas, sowing grasses and crops that hadn't developed naturally yet, all that stuff would really mess up the future. Maybe they don't care about messing up the future, causing paradoxes, or creating splintered time streams. Their actions could feasibly prevent the formation of the human race altogether.
Gosh, that was geeky.
But yes, going back to the time of the dinosaurs seems like a very poorly thought out idea beyond the "cool" factor. That's not the world humans adapted to survive in. If they're doing it so that they have a long time before they reach the modern age again, then they have that pesky asteroid to deal with in 20 million years.

That's the type of "change the past" time travel that I can accept. And, yes, I know it's "just a show." But the execution of a series' concept can be so monumentally silly that you can't watch it.
BTW, "Preview" is our friend.
