Sorry for the late reply.

The skull of the Indominus look much like Giganotosaurus, particularly because of how elevated its jugal is that gives it this "gap" in the back of the upper jaw just behind the teeth that you see in Giga.

As for the lower jaw, I'm convinced it's a mix between T. rex and Majungasaurus. There's sone good shots from the film has a thick surangular bone that no animal used in the creation of I. rex possesses except T. rex. Not even the cloned raptor has a surangular bone like that. However, the dentary doesn't seem to be of T. rex and looks more like Majunga (the dinosaur at the top of this image).
