This fight is most likely 50/50.
To solve this problem, we must first look at the combatants.
Tyrannosaurus
Weight: 6.4 tons
Length: 12.8 metres
Weapons: Bannana-shaped serrated teeth that could break through bones and an 8 ton bite force.
Advantages: Stronger bite force, probably more agile, larger brain.
Disadvantages: Much smaller, its arms were very small and weak, and it could probably take less wounds.
Spinosaurus
Weight: 12 tons
Length: 18 metres
Weapons: Long, deeply rooted teeth, a 3-5 ton bite force and long, hook-like claws on flexible arms.
Advantages: It was much larger, and its weak spots (head and neck) would be out of the reach of its opponent. It was more muscular and likely could take more damage.
Disadvantages: Slightly weaker bite force, and the fatty hump on its back would make it slightly less flexible.
The fight is almost completely balanced.
My opinion: Personally, I think the t-rex would have won because the spino. usually hunts for fish rather than dinosaurs while the t-rex regularly hunts, and also if spino falls, he dies because spino's spine is connected to the fin.
Tyrannosaurus Rex! not spinosaurus
Maybe the people you know believe that Spinosaurus could fight a Tyrannosaurus, but, most people believe the latter. In fact, Spinosaurus and Tyrannosaurus did not even live in the same time period, let alone the same continent.
a rex was dumb that a spinosaurus could kill it is all i can say.
Spinosaurus, although both the Allosaurus and commonly known Tyrannosaurus Rex are close behind.
spinosaurus thought that the carcharodontosaurus was tyrannosaurus rex that's why they get into fights.
Normally Tyrannosaurus rex is said to be the "King of the Dinosaurs". but if you think in size it is the Spinosaurus
It is not possible that in history the Spinosaurus would have ever encountered the Tyrannosaurus rex. The Spinosaurus was alive in the early crustantean period while the T-rex was alive in the late part of the crustantean period.
When I ask people what their favorite dinosaur is, by far the majority say Tyrannosaurus rex. I haven't asked a lot of people, but nobody has answered Spinosaurus. Technically, I don't have a very large sample size, but I would still guess that Tyrannosaurus is far more popular than Spinosaurus.
Actually it depends on what type it is if it was a bloodthrsty spino it would knockout the t rex but it is true that a spinosaurus is a better fighter and if u diaagree please answer differently
It was previously thought that the Tyrannosaurus Rex was the king of the dinosaurs. However, recent evidence has proved this was wrong. The king of the dinosaurs was actually the Spinosaurus. Which was much larger, stronger, faster and far superior than the T-Rex.
Spinosaurus was likely more adapted to fishing than fighting. If the two ever could meet, it was unlikely a fight would have broken out however. Tyrannosaurus was more adapted to killing, with a bone crushing jaw, unlike Spinosaurus's long, and thin jaw. The only weapons Spinosaurus may have had against a dinosaur like T-Rex would probably have been its strong arms tipped with large claws.
Spinosaurus was larger than Tyrannosaurus, but they mostly hunted fish. Tyrannosaurus had a much greater bite force and regularly hunted large and dangerous prey like Edmontosaurus and Triceratops. They may have even lived in packs, which would give them a huge advantage. In a one on one fight, I would guess that either could kill the other, although in most combat between two species one will surrender before either die. As a final note, Spinosaurus and Tyrannosaurus lived on separate continents millions of years apart, and thus they never would have encountered each other in life.
