Preferably T-rex and other large ones. I went google searching and after looking at a few videos I realized that a well animated, rendered T-rex walking or moving in a realistic way turned me on far more than anything that is actually designed to turn people like me on. I can only imagine how impossibly horny a video of a tyrannosaurus chasing people down and devouring them whole (with sexy bulges) would make me if it was animated by someone who was actually good at it (and designed it to be sexy). I would pay a lot of money for something like that... but I don't know of any good animators that could do that well and would actually do something like that for money. I'd pay up to $100 if it was good enough and long enough.
