'Ice Age 3' Has Dinosaurs, Apparently

From iwatchstuff, It's hard to say it much better than Meg, who sent this in: "New poster for Ice Age 3. What the hell?"

What the hell indeed. I only have vague memories of catching part of Ice Age on TV, but I don't remember there being dinosaurs. So they're just adding dinosaurs, now? I'm not saying a cartoon has to be history book-accurate, but come on, at least have some consistency. I'll graciously accept a Flintstones-style world--where man meets dinosaur meets mammoth meets the voice of Ray Ramano--but you have to start me there. To begin with a reasonably faithful vision of early mammals and then say, "You know what? Besides using one to open a stubborn can, I'm basically out of sabre-tooth tiger jokes. How about we add dinosaurs?" is more lazy and insulting than usual. Adding dinosaurs after mammals? Come on. And why is it so big? Is this like Godzilla or an actual dinosaur? Do they know the difference? What the hell?
