Spinosaurus vs. Tyrannosaurus Rex

I do agree with you but Tyrannosaurus hasn't lost its crown as king. Spinosaurus gets its own branch of royalty- The Pharaoh. Spino is vastly underrated by Rex fans that claim it was light, inflexible, had weak jaws and wasn't as powerful as Tyrannosaurus. It was over 20 feet tall assuming it had legs like those of other spinosaurs. Its claws themselves could be lethal due to both size, sharpness, and force they could be swung with. [img]http://oi46.tinypic.com/km1yb.jpg[/img] The only advantage T. rex had was bite and even then Spino's bite was lethal. It's like choosing between getting sat on by a forest elephant covered in crocodile teeth or bush elephant covered in serrated rail road spikes. You're going to very likely die either way. Spino could grapple and slash as well as see very well and likely had armor to protect itself from the deadly animals it shared its habitat with. It was just too big. Also, intelligence isn't a determining factor because even the smartest dinosaur (Troodon) was only as smart as today's average mammals. Somewhere between opossums and house cats. T. rex had a small cerebrum (the part of the brain used for thinking) and it looked and was proportioned like an alligator's brain in relation to skull and body. Thus, Tyrannosaurus rex was about as smart as a modern day american alligator. Not stupid but not smart enough to have an advantage. The only prey I can see Spino taking as big or bigger than itself is Aegyptosaurus, Sarcosuchus, Young Paralititan or maybe some other sauropods that were smallish. Definitely preyed on Ouranosaurus and Stomatosuchus on a daily basis though on top of sharks and other stuff.

While all of the evidence points towards Spino winning expect to get some "I disagree, Rex would win" "Spino was actually pretty light" " Rex was really stronger" " Spino was unagile because of its sail" "Spino's bite was low, Rex had a bite of up to 9 tons" "IN MY OPINION, JUST MY OPINION" And "We'll never know for sure". A few people might agree Spino would win, but most will say Rex does due to bite, strength, size and agility. Only the first of those is even accurate. No 50 foot T. rex exist.

Let's get something straight, this topic has been done over and over again. At this point, you're basically beating a dead horse. The end result is always the same. Most agree that T-rex would win more often, with Spino coming out on top once and a while. I'm not gonna bother getting into facts and theories. We all know them at this point. In my opinion, Tyrannosaurus would win 60-65 percent of the time and Spinosaurus would win about 35-40 percent of the time.

Rex Fan is right. You're right RexKiller, there probably will be people who say what you just listed. Thing is though, if people don't say "In my opinion" or something similar, it makes some of the fans mad.

This was totally biased, we WILL never know who wins against who because A) we didn't live 65 million years ago B) They didn't live on the same continent, Spino living on South America, T-Rex living on North America T-Rex had a lot more competition than what you gave, it had lots of challenges with Triceratops Anklyosaurs (forgive me if I misspelled that) Those Herbivores were extremely hard to kill and were considered to be the most advanced Herbivores ever, with Triceratops deadly 2 horns, and Anklyosaurs armor and deadly tail it had. Considering your title is "Spinobro" you completely was biased to Spino. Yes Spino was Bigger than a Rex, but that doesn't mean it would win because of that. The T-rex would win a lot more than you gave it credit for. I say the T-rex wins 65% to 35% for the spino if I had to give my ratio.

RexKiller When we say "Spino is light", that is in comparison to size. "Rex was really stronger", is means pound for pound. Don't know what to say about the sail, maybe it did affect agility slightly. "Spino's bite force was low", in comparison to Rex's. In my opinion (there it is, opinion), Rex's bite force would not exceed 7 tons. "We'll never know for sure", is pretty self explanatory. "In my opinion", is also pretty self explanatory. Some people can think that Rex would win more often than not, some people can think that Spino would win more often then not. It's all just opinions.

Lost World: Jurassic Park He is team Spino just checked, his cover pic is pretty cool, just saw his forum signature "Spinosaurus... The Real King of The Dinosaurs", and he has the same profile pic as FACT DUDE. Spinobro64 What do mean "No evidence of pack hunting"? There actually is evidence that Rex hunted in family groups. And for intelligence, I'm pretty sure I remember hearing it was in the ballpark of a Newborn kitten. You didn't give Rex as much credit as you should have. There truly is no evidence that Spino hunted in packs. The debate is pretty much dead however, and all you've done is pretty much nothing for our opinions.

Oh, and Spinosaurus lived in Africa, not S. America Lost World: Jurassic Park ;)

Either way, Tyrannosaurus' close relative Albertosaurus and the other tyrannosaur Yutyrannus have been found in groups. More primitive carnivores like Mapusaurus, Giganotosaurus, and Allosaurus are often said to be pack hunters. Why not the more advanced Tyrannosaurus which has been found in family groups composed of juveniles and adults?

What did you mean, "Able to beat most dinosaurs in a race, ESPECIALLY T-Rex"? There were dinosaurs that were slower than T-Rex. Once again, you're right Rex Fan.

Let's say, just for a minute, that Spino was bigger than Rex(I still don't believe that to be honest), then how on earth would it be faster? The highest estimates put it at 20 tons! How can a 20 ton animal move faster than a 7-10 ton animal? Trust me, a rabbit can outrun me any day and I'm way bigger.

Good comparison Rex Fan. The more I re-read this, the more comments I have on this. "Spinosaurus also took on big dangerous prey much bigger than itself,T-Rex preyed on smaller prey and had almost no competition." By smaller prey, you are referring to Triceratops and Ankylosaurus, and Edmontosaurus. Lets focus on the first two right know. Triceratops (three horned face) was a large ceratopsian, and anything that it hit head on, would be killed, or severely wounded by the impact. Ankylosaurus had armour that even T-Rex couldn't bite through. It also had a tail club that could break bone, and potentially kill, a predator. Edmontosaurus wasn't completely defenceless though. It could probably do some damage with its tail. Now put Spino in that environment. How long will it last before getting killed by something or starving to death?

Indeed. It's not just Spino's jaw strength, but the shape of his teeth. Conical teeth are great for grasping, especially slippery prey like fish, but don't tear flesh very well. Spinosaurus would have a hard time using it's jaws to dispatch prey bigger than Ouranosaurus. Spinobro64, you also listed only 1 disadvantage for Spinosaurus. You gave quite a few for Tyrannosaurus. Based on what you said, I can tell you're getting your info from Monsters Resurrected. Keep in mind that's the show that depicted Spinosaurus killing Carcharodontosaurus with a single claw swipe, picking up a 30 ft Rugops and shaking it around in it's jaws, and killing a Sarcosuchus with a bite to the neck. Almost, if not all of this, is far fetched and unlikely, if not impossible.

I think if Spino fell at all, it would be injured. Didn't that show also have Charcaradontosaurus WAY smaller than Spino?

Yes. It was showing Spinosaurus as being far bigger than Carcharodontosaurus. I love how they had Spino pick up Rugops, which is at least half Spino's size, in it's jaws and shake it around. That's probably impossible for any animal to do. That's the only time I've ever seen a dinosaur with jaws about 6-7 ft long, in my opinion, pick up a 30 ft long, 1-2 ton dinosaur and shake it around.

I mean, just look at this! [url=https://www.youtube.com/watch?feature=player_embedded&v=W--8HyuauDQ]Spinosaurus in Monsters Resurrected[/url] (This does not even show him taking out a Carcharodontosaurus with a single claw swipe)

Seen it before. It wasn't very informative, and I really doubt much of what it did in the video is possible.

I agree. It is perhaps the least accurate depiction of Spinosaurus yet. It's jaws were way too robust for one thing. Planet Dinosaur had a better depiction in my opinion.

I think Spino is around the middle. 8 tons, 60 feet, 20 feet tall, hips by the way. I think it has a bite of around 4 tons. It is twice as long as a saltwater crocodile, who has a bite of 2 tons. There is also a direct correlation on how big a crocodile is compared to its bite force. And i really think that Spino could run at up to 30 mph, it has huge legs! It also had ginormous (that's a word) arms that had truly wicked claws at the end. That being said, T. rex was 9+ tons, 40-43 feet long, and around 16-17 feet tall. It had railroad spiked teeth that are just perfect for crushing bone. Pound for pound, T. rex is the heaviest. It had some really bad opponents like Triceratops and Ankylosaurus. Even Edmontosaurus could cause some serious trouble. It is pretty smart too, and has great eyesight. It does have puny arms however. It really want too fast either. All in all, I'd say that they have a 50-50 percent chance of beating eachother.

I'm sorry for undertaking T-Rex,it's just people do that to spinosaurus to,thank you Rexkiller and Rexfan 684:) for changing my view Tyrannosaurus rex:hunted in packs smaller than spinosaurus,both strong,trex has stronger bite force,spinosaurus was faster,hope that clears things up I just wanna know if people even appreciate a great animal like spinosaurus ?it seems everyone only likes Tyrannosaurus.... Thank you Rexkiller
