Spinosaur V Indominus Rex

The Spinosaur has an advantage in size and weight,
but I-Rex is more intelligent, can camouflage itself thanks to cuttlefish DNA
AND could call the aid of raptor should the need arise,
except for that damn Blue raptor.
Been hanging out with those damn humans for too long...
I. Rex also has what appears to be longer forelimbs thanks to Therizinosaurus DNA with sharper, raptor-like claws,
but that doesn't necessarily mean stronger forelimbs...
Though I. Rex should have a stronger bite force, seeing as it has inherited many traits from T. Rex,
it can also open its jaws incredibly wide because of Pit-Adder DNA (which also allows it to see in infrared),
so this would mean that it would have more flexible jaws than T. Rex,
which would expend jaw power, though it would still be more powerful than the piscevorous Spinosaur's.
So the only way this fight could go 'either way' is if they dance by a deep, wide river shore, like on Isla Sorna.
If the Spinosaur manages to pull I' Rex into the water, it's tickets for the hybrid.
If not, I. Rex will most likely have a long-term food supply.
I also went with the JP3's Spinosaur as opposed to the 'new Spinosaur'
that was recently brought to light by Ibrahim et al.
since it is built very strangely and would really struggle to move on land with such ridiculously proportioned limbs.
Seriously, how did THAT thing move around?
Its forelimbs aren't even made for quadrupedic movement, nor can it walk like a biped with such short legs.
Personally, I think they have constructed it with the use of bone structures from different Spinosaurs varying in age and size.
