Tyrannosaurus rex
Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), commonly abbreviated to T. rex, is a fixture in popular culture. It lived throughout what is now western North America, with a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous Period, 67 to 65.5 million years ago.[1] It was among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small, though unusually powerful for their size, and bore two clawed digits. Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it was the largest known tyrannosaurid and one of the largest known land predators. By far the largest carnivore in its environment, Tyrannosaurus rex may have been an apex predator, preying upon hadrosaurs and ceratopsians, although some experts have suggested it was primarily a scavenger. The debate over Tyrannosaurus as apex predator or scavenger is among the longest running in paleontology. Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen, FMNH PR2081 ("Sue"), measured 12.8 metres (42 ft) long, and was 4.0 metres (13.1 ft) tall at the hips. Mass estimates have varied widely over the years, from more than 7.2 metric tons (7.9 short tons), to less than 4.5 metric tons (5.0 short tons), with most modern estimates ranging between 5.4 and 6.8 metric tons (6.0 and 7.5 short tons). Packard et al. (2009) tested dinosaur mass estimation procedures on elephants and concluded that dinosaur estimations are flawed and produce over-estimations; thus, the weight of Tyrannosaurus could be much less than usually estimated. Other estimations have concluded that the largest known Tyrannosaurus specimens had a weight exceeding 9 tonnes.

Spinosaurus aegyptiacus
Spinosaurus is a genus of theropod dinosaur which lived in what is now North Africa, from the lower Albian to lower Cenomanian stages of the Cretaceous period, about 112 to 97 million years ago. Spinosaurus may be the largest of all known carnivorous dinosaurs, even larger than Tyrannosaurus and Giganotosaurus. Estimates published in 2005 and 2007 suggest that it was 12.6 to 18 metres (41 to 59 ft) in length and 7 to 20.9 tonnes (7.7 to 23.0 short tons) in weight. The skull of Spinosaurus was long and narrow like that of a modern crocodilian. Spinosaurus is thought to have eaten fish; evidence suggests that it lived both on land and in water like a modern crocodilian. The distinctive spines of Spinosaurus, which were long extensions of the vertebrae, grew to at least 1.65 meters (5.4 ft) long and were likely to have had skin connecting them, forming a sail-like structure, although some authors have suggested that the spines were covered in fat and formed a hump. Multiple functions have been put forward for this structure, including thermoregulation and display. Dal Sasso et al. (2005) assumed that Spinosaurus and Suchomimus had the same body proportions in relation to their skull lengths, and thereby calculated that Spinosaurus was 16 to 18 meters (52 to 59 ft) in length and 7 to 9 tonnes (7.7 to 9.9 short tons) in weight. The Dal Sasso et al. estimates were criticized because the skull length estimate was uncertain, and (assuming that body mass increases as the cube of body length) scaling Suchomimus which was 11 meters (36 ft) long and 3.8 tonnes (4.2 short tons) in mass to the range of estimated lengths of Spinosaurus would produce an estimated body mass of 11.7 to 16.7 tonnes (12.9 to 18.4 short tons).

Correct. That's why tyrannosaurus has tiny arms to balance the head
Actually, the tail, not the arms, balances the head
But little arms help balance as well. If tyrannosaurus had large king Kong arms, he would eventually fall forward everytime he makes a step. Large arms would put too much weight on the cranial area.
But what relevance does the size of the arms of tyrannosaurus have in this match up? Unlike dinosaurs such as allosaurus, they weren't as useful as weapons or grappling tools.
If T.rex was close enough, it might be able to grab Spino with its arms and grasp on. And, contrary to popular belief, those arms were far from weak, both arms were shown to be able to lift 400 lbs.
I did hear somewhere that the arms of tyrannosaurus were much stronger than even human arms, but they are nothing compared to those of spinosaurus. And how would the tyrannosaurus even be able to get a good grip? Those small arms could possibly be used, but they wouldn't do much.
Again, get extremely close (probably from the rear) and MAYBE you can get somewhat of a good grip. I'm not trying to support T.rex, but it could probably happen. But yes, those arms are nothing compared to other theropods.
I rather doubt it, are those arms even built for grappling on to things??

it would totally rely on its jaws

The dinosaur guy is long gone now. I haven't heard from him in the past few days. However, we should just pipe down about him before he comes back and starts trolling again.

Their numbers are dwarfed by that of Tyrannosaurus fanboys though, I encountered a lot of Tyrannosaurus fanboys in deviantart and youtube...but I can count the number of Spinosaurus fanboys I encountered in one of my hands...

At least if the arms of t rex are ridiculous, those of spino are not much more impressive in body ratio.
t rex isn't as heavy like a cow, it was heavy.
No theropod had arms like godzilla

T-rex arms evolved cause his ancient relatives had longer arms, and they didn´t use it so much so T-rex compensates the arms with the land most powerful bite force and his weight is 30% heavier than previously thought... please research if you wanna talk...

That mass estimate is based on a disgustingly fat Tyrannosaurus.

That being said, Kurtz can't really be taken seriously when it comes to dinosaurs...
