CompsognathusMember0 XPMar-30-2013 8:40 PMWho would win, Tyrannosaurus rex or Spinosaurus aegyptias? I feel T-rex would win. A bite force of 3 to 9 tons per square inch, pack hunter, overall smarter. Spinosaurus had larger claws on it's hands, but it's bite force was pretty pathetic. Plus, a 4 to 6 ton Spino is about half the weight of a 8 to 10 ton Rex. That's my opinion, what about you guys?
PS- What's your favorite dino in general? T-rex is mine."Men like me don't start the wars. We just die in them. We've always died in them, and we always will. We don't expect any praise for it, no parades. No one knows our names."

CompsognathusMember0 XPApr-02-2013 4:24 PMAs some of you know I am on team Spino. It was a really difficult decision to make considering I LOVE t-rex and am amazed at the ferocity of t-rex in jurassic park. I agree that it is improbable that Rex would lose to Spino in a fight, because T-rex has the skull, weight, and speed of a killer, while spino mainly ate fish and is lighter and more delicate with that sail-fin.
My favorite dinosaur is probably dilophosaurus."Either way, you probably won't get off this island alive."

Tyrannosaurus RexMember6270 XPApr-03-2013 4:48 PMT.Rex would win most of the time (it is possible for T.Rex to have a bad day e.g. JP3). I was actually kind of surprised reading Dinosaur.Fanatic's comment. I have never actually seen anyone who is team Spino, but still agrees T.Rex would win because most of the time, Spino fans are so heavily biased in Spino's favour, that it is comedy more then anything. I am on Team Rex, but I do like Spino. On other discussions on different sites, people said Spino's sail was an advantage, and others said that because Spino had long arms, it could rip T.Rex's head off before T.Rex got close enough (LOL). Anyway, I do wish that there where more Spino fans like Dinosaur.Fanatic, looking at this statistically, not just by which one they like better.
T.Rex would likely win due to superior bite force, overall strength, and toughness.Jack of all trades. Master of none
CompsognathusMember0 XPApr-03-2013 10:30 PMI'm going to set this straight right now for anyone who thinks Spinosaurus would win. T-Rex would win, u can argue it all u want but here r reasons why. T-Rex does have a greater bite force. But that doesn't mean it wins automatically. Spinosaurus had longer arms than T-Rex but that doesn't mean anything. If u look at what the fought and ate during their time you will know the difference between them. T-Rex lived with Triceratops, Ankylosaurus, and Edmontosaurus. It was difficult for T-Rex to get a meal against tough prey. Triceratops 8 foot skull with 3 foot horns. Ankylosaurus was covered in armoured bone and had a deadly bone breaking club. T-Rex had challenges. Now Spino is larger no doubt , had longer arms with big hook like claws. Those were used for fish!! Its snout was long to catch fish! It ate fish! It had its nostrils up closer to its eyes so it could stick its mouth in the water and still breathe. They also killed some juvenile dinosaurs. But those r juvenile. Nothing like T-Rex. Spinosaurus would piss him self if he saw T-Rex coming at him.CompsognathusMember0 XPApr-04-2013 3:24 PMYeah, I think T-rex would win. Spinos sail would probably be a disadvantage. It would make him less agile and was full of blood vessels. It a rex bit it, it would be like a big blood filled cookie for him. Yum, haha. I even think that, while Spino was 6 feet longer and maybe taller, T-rex was much heavier, and therefore, bigger. Spino=4-6 tons, T-rex=7-9 tons or more. Just sayin"Men like me don't start the wars. We just die in them. We've always died in them, and we always will. We don't expect any praise for it, no parades. No one knows our names."

CompsognathusMember0 XPApr-04-2013 7:56 PMThey weights were about the same actually, both around 7 tons give or take a ton. That Rex in JP3 was the smallest T-Rex of all the other movies and it was probably a young one too. That was a disadvantage for it.
CompsognathusMember0 XPApr-06-2013 12:18 PMAll of the paleontological evidence points toward Tyrannosaurus taking the cake. He was a larger carnivore when it came to mass, he had to take prey that was not only well armored, but extremely deadly. Spinosaurus ate fish, the only real challenge I could see a Spinosaurus facing would be something like a Leoplurodon, maybe even Predator X. I'm also still quite skeptical on the size of Spinosaurus they've never uncovered a full skeleton, only some pieces. Those were destroyed in a museum in Europe during WWII. I just didn't appreciate the fact that they had a new dinosaur come in out of nowhere with no backstory and take down our tyrant lizard king. Either way, evidence points to Tyrannosaurus defeating Spinosaurus.CompsognathusMember0 XPApr-06-2013 12:56 PMI agree. Spino ate fish, small dinosaurs, and carrion. T-rex ate ceratopcians, ankylosaurs, Alamosaurus, duck-bills, etc. Spinosaur was longer, but Rex was heavier and stronger. Spino did live w/ Charcarodontosaurus and the giant croc Sarcosuchus, but would likely back down if he came across one. Tyrannosaurus was also more advanced. More intelligent. He was the smartest, fastest, strongest, and quite possibly the largest terrestrial carnivore ever."Men like me don't start the wars. We just die in them. We've always died in them, and we always will. We don't expect any praise for it, no parades. No one knows our names."

CompsognathusMember0 XPApr-11-2013 11:21 PMSpino obviosly would have won larger size, heavier, and he had arms unlike t-rexs stub arms. and about this greater bite force no one has seen a spinosaurus also spinos teeth were like a crocs teeth. crocodiles eat large animals such as water buffalo, and zebras. anyway t-rex couldnt have fitten his large fat mouth around spinos large sail anyway.
CompsognathusMember0 XPMay-09-2013 2:56 PMI like to think the JP3 Rex was old and weaker XD cause im sure Rex would have the advantage in a fight like that. It gives me peace of mind hahaha
CompsognathusMember0 XPJul-10-2013 10:01 PMI think Spino and rex would win equally, they have their own powerful weapons, Spino could easily rip T. Rex's throat out, and T. rex could easily rip Spino's head off, but if they fight, it will be very even.Hi
Tyrannosaurus RexMember6270 XPJul-10-2013 10:32 PMIn a Rex vs Spino fight, they are so evenly matched, that the battle could last for hours, and be ended by environmental factors, what they are fighting for, and experience. I did a discussion on things that could affect a Rex and Spino fight, but it didn't get that far.Jack of all trades. Master of none
CompsognathusMember0 XPJul-11-2013 8:44 AMWhoa, this post was from a long time ago, but ok. Some of my views have changed since I made this post. Many of you have probably seen my weight estimates for Spino go up from 4-6 tons to 5-7 tons for example. Now, that said, I still think Tyrannosaurus would win about 60 percent of the time. Spino, about 40. Like MrHappy said, it would likely come down to something out of their own control. "Men like me don't start the wars. We just die in them. We've always died in them, and we always will. We don't expect any praise for it, no parades. No one knows our names."

CompsognathusMember2 XPJul-24-2013 4:53 PMI change my opinion.
I think that this is a 50/50. Both were huge and dangerous.
CompsognathusMember0 XPAug-16-2013 10:28 PMIf you look at it,why do we argue about this,can't we just appreciate these amazing creatures,the truth is an even match 50% for each,plus they would never fight cause they lived in separate places.welcome to the new age
CompsognathusMember0 XPAug-16-2013 10:31 PMRex Fan 684,I know T-Rex is your fave but I wanna know if you can look into spinosaurus and post your findings,he may not beat T-Rex or not, we will never know,I just wanna see what you find when you research it.thank youwelcome to the new age

CompsognathusMember0 XPSep-14-2013 4:53 PMwell spino because he was the biggest therapod to walk the earth no giganatosaurus wasnt the biggest spino was even at juvinile he was bigger than a mid aged t-rex
CompsognathusMember0 XPSep-16-2013 6:52 AMWelcome to the best encyclopedia of dinosaurs ever made!

@ penguinsaurusrex
Bigger isn't always better.
Spinosaurus may be larger (in terms of length and height, and probably weight), but it just wasn't built for combat, in my (and a few others) opinion. Sure, Spinosaurus lived with Charcarodontosaurus, but the difference in their diets allowed for them to co-exist.
Rex on the other hand, while it didn't have competition from other large carnivores, it's prey was more than enough to fill that slot.
I'm not going to get into facts, if you really want to see pretty much anyone's opinion on how it would go, please refer to previous discussions.Jack of all trades. Master of none
CompsognathusMember0 XPSep-16-2013 7:04 PMThe statement that Tyrannosaurus did not have competition is actually not too truthful. While Nanotyrannus was probably not a problem, a large pack of raptors might at least present a mild problem. Not to mention T-rex had it's own version of Sarcosuchus aka Deinosuchus. Just a thought."Men like me don't start the wars. We just die in them. We've always died in them, and we always will. We don't expect any praise for it, no parades. No one knows our names."

Tyrannosaurus RexMember6270 XPSep-16-2013 7:05 PMDidn't think of that. I meant more all the time threats, not just once in a while threats.Jack of all trades. Master of none
CompsognathusMember0 XPSep-16-2013 7:28 PMAnd that's why Oxalaia is the best Spinosaur. Jk, that is Sigilmassasaurus. I know that this really doesn't relate to Spino vs Oxalaia, but the Argentinian was the second biggest predator of the time, and not the deadliest either. It was a more land based Spinosaur, and was porprotionatly as heavy as Spinosaurus, if not heavier. Hi
CompsognathusMember0 XPSep-16-2013 7:30 PMWhat get's me is that this is one of my first discussions ever and it's still kicking, haha
My first discussion was about Tyrannosaurus. Nothing more. Just T-rex, haha"Men like me don't start the wars. We just die in them. We've always died in them, and we always will. We don't expect any praise for it, no parades. No one knows our names."

CompsognathusMember0 XPSep-16-2013 7:34 PMI saw that this post was active, so I thought I'd join in for fun. I do think that when it came down to Spino vs T. rex, it would, be very, very even. A little bit on Rex's favor though. If it was Oxalaia vs rex, then it would be different. Okay, its 1 ton less than Spino, and 10 feet shorter, but it lived in the most dangerous place in dinosaur history, and you can't deny that. Argentina was literally crawling with carnivores, and the only food to eat is Titanosaurs. You have to be tough or food.Hi
CompsognathusMember0 XPSep-16-2013 8:46 PMWell, as I fight writer, I probably shouldn't get involved in this, but what the heck. Why not.
Okay, so here are Spinosaurus' advantages
Spinosaurus: long and powerful arms, long and sharp claws
Longer skull and powerful neck
Powerful bite (4-5 t)
Heavier and taller
Can get up if knocked on its side
Stronger (when you have a giant muscular ridge on your back from neck to tail tip, you're strong as hell)
Intimidating muscular ridge
Possibly some sort of armor (dealt with crocodiles and sharks daily)
Swimming ability
Way more experience fighting large carnivores (Bahariasaurus, Sauroniops, Sarcosuchus, Carcharodontosaurus, etc.)
Possibly reflexes (catching fish flying down a stream requires amazing precision and timing)
Now T. Rex's advantages
More powerful bite (6-6.5 vs 4-5 t)
Deadlier teeth (thicker and serrated)
Possibly agility (didn't have the sail, but it did have a restricting short body with wide hips, so this may not be an advantage)
Better sense of smell (perhaps the best ever)
Possibly better hearing
Handled deadly prey (Triceratops, Ankylosaurus)
Both had excellent depth perception and intelligence, so those X factors don't come into play.
I won't voice my opinion on the outcome, I just stated unbiased and supportable advantages each has.Announcement Coming Soon
Prepare yourselves, DinoFans!
CompsognathusMember0 XPSep-16-2013 10:22 PMI must agree with a bite of around 4 tons. It is more than twice athe size of a saltwater crocodile, and they have a bite of around 2 tons. Scale the fact that size matters with bite in crocodile world, and you have a redonculusly strong bite force.Hi
CompsognathusMember0 XPSep-18-2013 2:19 AMWell, even then, the saltwater crocodiles that had measured bite forces were only 8 feet or so... I imagine Lolong-sized animals would bite down with at least 3 or 3.5t, coming in to the lower range estimates for Tyrannosaurus. If it hit 4, I wouldn't be surprised. I don't know how to do square cube force scaling or whatever like my sister, but scaling from a false gharial, a crocodilian with a 6 foot skull (Sarcosuchus) could bite down with 4t psi.
And Spinosaurus' skull was exceptionally more robust than its kin's.

Spinosaurus is much closer to false gharial than gharial, giving it a bite of roughly 4t, though if its ridge muscles connected to its neck, giving more power to the skull, additional force would be provided.
