The Stegoceratops have disturbingly large and dangerous horns. This creature would be more of a challenge than the Tyrannosaurus would be. Stegoceratops however, due to all of the heavy weaponry, would be rather slow. The best place for the Indominus to attack would be the side of the head, away from the swinging tail and not directly in front of the horns. There the Indominus would tear into the hide of the Stegoceratops and attempt to bleed it out. The problem is, the Stegoceratops isn't going to just stay still and let the Indominus Rex attack its weak spot. It is going to run and fight and fight until it can fight no more. All the Stegoceratops needs to do to win is to land one successful hit on the hips or legs, and the Indominus would be crippled. From then it would be an easy kill. In my opinion, despite the massive size and extreme strength and intellect of the Indominus Rex, It would LOSE to the Stegoceratops.
