If it was a land battle Trex would destroy the spino but in the water spino would beat the rex. So from all the evidence its concluded that Trex would win 80% of the time due to its bigger brain better eyesight and stronger bite.
In Jurassic Park 3, the Spinosaurus easily defeated the T-rex by clenching its neck tightly between its jaws. While this might be possible with a smaller organism, it's unlikely that a Spinosaurus would be able to do that with a dinosaur as robust and muscular as a T-rex.
Anky could easily break those bones, rupture those organs, or even instantly kill Spino. Giganotosaurus, Tyrannosaurus, Velociraptor, or Stegosaurus would also lose to Ankylosaurus.
Wiz: "The paleontology is also somewhat outdatted, Spinosaurus was not quadrapedal. Tyrannosaurus does not live in a swamp and tyrannoaurus certainly had more than just its bite for the battle. The winner is rexy."
Wiz: Though Spinosaurus could do some serious damage and gave Indominus some nasty scars, it was nothing compared to how brutal and merciless the Indominus was. Though made weaker because of her blindness, she was still powerful and smart enough to perform the actions required of her to win.
In a cage match, T. rex has several adaptations that might give it an edge over Giganotosaurus. But don't place your bets yet. The bigger dinosaur could leverage its skill at hunting massive sauropods to take down a smaller-than-usual foe.
In any sort of aquatic or partially aquatic space, the Spinosaurus might have the advantage because of its superior mobility. The Spinosaurus was also longer and, with its spinal fin, taller than the Giganotosaurus. However, in most land-based scenarios, Giganotosaurus would likely have the upper hand.
Spinosaurus, on the other hand, had two weapons and 4 major advantages when it came to fighting other large theropods. It had huge claws that could clearly do serious damage, and a bite that is far less than a Tyrannosaurus' but much stronger than most give it credit for.
If they wanted to follow movie cannon, the Spino in JP3 is 3 feet longer than Rexy the largest Rex in the films at 40 feet. In real life Spino was 10-15 feet longer, and even in JPOG the Spino was significantly larger.
Large enough to swallow a human whole, gigas were apex predators in their environment who likely fed on young sauropods. In this battle of titans, the two foes were evenly matched. On a good day, the giant, powerful Giganotosaurus could definitely kill a T-rex.
The Spinosaurus recovered quickly from the blow and managed to out-maneuver the Tyrannosaurus and bite deep into his neck. Bellowing in pain, the T. rex groaned out in agony as the Spinosaurus gripped his neck with it's arms and snapped the rival dinosaur's neck, killing him instantly.
Despite its aforementioned strengths, the Spinosaurus is by no means without weakness. Though its jaws are very much an improvement over the marine-suited jaws of its ancestors 97 million years prior, they are not without flaws.
But in other cases, it will actively hunt on land like traditional theropods. From time to time, Spinosaurus will also target other prey like ceratopsians, stegosaurs and ankylosaurs they will stay away from large sauropods. Based on live observation, Spinosaurus can kill it's prey in different ways.
Now if Spino and rex were to fight who would win? If it was a land battle Trex would destroy the spino but in the water spino would beat the rex. So from all the evidence its concluded that Trex would win 80% of the time due to its bigger brain better eyesight and stronger bite.
rex lived in North America 65 million years ago, while Spinosaurus lived in North Africa 30 million years earlier), the question of who is mightier remains.
Mosasaurus attacks Spinosaurus, but couldn't land a hit until, he crush Spinosaurus onto the ocean floor and tosses him to the ice sheet above and crash into Spinosaurus. However, Spinosaurus uses the icicles above to kill Mosasaurus and was successful, thus killing Mosasaurus.
Tyrannosaurus can think and move slightly quicker, and deliver more precise blows and be less likely to miss. It's kind of a 60–40 thing, since each dinosaurs' advantages are slight and both can kill with a single bite, but the superior senses, speed, and intelligence of Tyrannosaurus give them an edge.
Hiro: One foot taller, six feet longer, two tons heavier and years more experienced, the Spinosaurus had it's fair share of advantages in this battle. But everything else it could do, Indominus could do better.
It was mentioned that the Indominus rex would be larger than the T. rex when fully grown. Including the shape of the head in some parts from Giganotosaurus.
In actuality, Carnotaurus sastrei was smaller; roughly about 9–10 feet tall and 26–29 feet long (while Tyrannosaurus was 13–15 feet tall and 40–50 feet in length), thus making Carnotaurus slightly larger than Iguanodon, the main dinosaur of the movie.
T-Rex VS Therizinosaurus who would win | Fandom. But in an over the top battle to the death scenario, T. rex wins. Deinocherius would be a better sparring opponent, but Theri ain't bad either.
If O. megalodon and T. rex were to somehow meet after the shark threw itself onto the land, then it doesn't seem like the dinosaur would stand a chance. The aquatic beast is bigger than it in every dimension, and more than capable of crunching through tough bones.
