Igaunasaurus-Rex (I-Rex) 2

Okay, so the Indominus-Rex is Jurassic World was cool, but maybe on an alternate Earth where iguanas became carnivorous apex predators this I-Rex would be as adaptable to blending in with it's environment as the Indominus was, giving this creature an evolutionary advantage of being able to take down it's quarry due chameleon abilities. On this alternate Earth the Iguanadon and the T-Rex never evolved. Imagine if on this alternate Earth dinosaurs never died out and continued evolving into hominid species.

In this second photo of the I-Rex you can see it bearing it's carnivorous teeth, as if about ready to charge at it its intended quarry.

You can see a little bit of a difference to the spine of this I-Rex to that of the other one, this is due to regional differences with some variation.
