I know lots of other discussion are just like this, but I am trying a different way of comparing them. Advantages: Rex- Huge bite force, binocular vision, sense of smell, intelligence Spino- Huge arms, huge claws, more intimidating (appearance) Disadvantages Rex- Tiny arms, slow, if it fell, it would likely die Spino- Weak jaws (by comparison), slow, likely death if it fell Uniqueness Rex- Oversize head, tiny arms Spino- sail, huge arms for large predator, swimming Known for Rex- King of the dinosaurs, one of the largest carnivores Spino- Beat Rex in JP3, sail, bigger than Rex How is this? Are my thoughts reasonable? Feel free to make any corrections, add something, and enjoy.

I think this is a 50/50. Both were huge and dangerous predator.

Spinosaurus, unlike T-rex, would have hunted in the water because paleontologists believe it had pressure sensors at the tip of the snout like a crocodile, would that have made the T-rex stronger because it was more used to taking down bulkier prey and weren't T-rex's teeth sharper?

Yeah, I like both. I just like Rex a bit more. Spino is top 5 for me though.

The T. rex was a fighter and far stronger. I read this interesting article The Tyrannosaurus Rex’s Dangerous and Deadly Bite "The dinosaur had the strongest bite of any land animal – even harder than we previously thought" By Brian Switek

Haha...!..not the T-Rex,Spinosaurus was the smarter dinosaur...!..just go and check up on some facts...the -T-Rex's vision was based on movement,so if we didnt move,we can easily escape the Rex,but not the Spino...we cannot stay like that in front of a Spinosaurus..!..It'll swallow us in a glance..!..he'll know that we're living or non-living if we even didnt move..!..and because the Spino also caught fish,it should probably have a higher IQ...catching fish is not like catching prey on land,catching fish is a 100 times difficult,and while catching fish,spino hunted land-prey too...it means Spino was smarter....than a T-Rex for sure..

Reading all three of your posts, I have a feeling that you don't really like Rex all that much. There is no proof that Rex couldn't see movement, and I remember hearing that it could see heat signatures (also unlikely). This may sound like a strange request, but could you please state that these are your OPINIONS. I have mine, and you have yours, and we prefer to have others say opinion, rather than, "This is what I think, so this is what it is." We have dealt with others that were worse than you (no offence guys, you're great now).

Tomcarterhestard, 2 things 1. T-rex seeing only movement is complete bull. It could not survive like that. The thought that T-rex could not see in movement is something created by Jurassic Park, not a proven fact or even an accepted theory. Tyrannosaurus almost certainly had binocular vision with a good visual filed overlap. 2. As far as intelligence goes, T-rex belonged in the same group of dinosaurs, the coelurosaurs, as Velociraptor, Deinonychus, Troodon, and modern birds. It's simply common sense that T-rex would be very smart. Spinosaurus belonged to a much more ancient group. A more primitive group. While smart for a spinosaur, I seriously doubt it was smarter than a Tyrannosaurus, a member of the smartest dinosaur group. Thank You

Tyrannosaurus did not necessarily have an oversized skull, just a very heavily-built skull. Spinosaurus actually had the longer skull of the two, although it was much shallower and thinner dorsally. I am talking about when spinosaurus is larger than tyrannosaurus, of course, as skull lengths are determined by an animal's size and head-body proportions.

Godzillasaurus, T. rex did have one of the biggest haeads proportionately. Spino did have a longer skull, but Size doesn't determine the animal's skull length. Take Giganotosaurus. It probable had a head of 6 feet while 46 feet long, but Spinosaurus only had a head of 7 feet at 60 feet long. 1 foot difference head, 15 foot difference body. There isn't that big of a jump with T. rex. Its skull is about 5-6 feet long, at 42 feet. Only one foot difference with three feet difference.

I wasn't talking about proportions; I was talking about an animal having a larger skull due to larger size. Giganotosaurus and carcharodontosaurus had paritcularly longer skulls proportionally than tyrannosaurus and spinosaurus, but that does not mean a bigger spinoaurid or tyrannosaurid will have a smaller skull. That is what I meant. Size does not determine proportions

Right, but you where sadeter body size deteremains skull length, and that's not exactly true either. Partially true, but not 100% spot on.

Proportions and size both determine skull length. Size as a whole does not do so, but that in conjunction with head-body proportions does. An example would be a similarly-sized carcharodontosaurus and tyrannosaurus; the allosaur would have a much larger skull.

I'm with Delta on this one, and we all know each others opinions. I personally think that Spino maxed out at 60 feet, but averaged around 50 feet. I think Rex averaged 40 feet and maxed out at around 45 feet. Let's not get into overall size, we all have DIFFERENT opinions on this topic, and it was a bloody stalemate, which is why we decided to kill the topic.

 

So Rex vs Spino is dead, it's nice that you have your opinions, but let's not get into which is bigger, that's what pisses people off (not to mention getting the regulars to swarm the topic).

 

So please, no more Rex vs Spino. Sound good?

Did what I say there just go in one side of your brain and out the other? Its literally the comment before yours. We all know this stuff, and we have all stated it at one point what we think would happen. The only Rex vs Spino discussions that were posted recently are by people who signed up recently, but as I've said countless times, Rex Vs Spino is dead, it's a stalemate between members, so we stopped.

Quote: I just dont understand why some scientists say that trex is likely stronger in comparison. -That is because it was much more heavily-built than spinosaurus. I say again, spinosaurus, despite having very robust and strong jaws, was designed to eat fish primarily. Its jaws and teeth alike were not designed for crushing but rather gripping. Tyrannosaurus, on the other hand, had both wider and deeper jaws in relation to length, telling us that it was designed for crushing. Spinosaurus was very strong in rostral, mandibular, and dental build. But it was designed for piscivory and gripping, not crushing.

While I agree with what has been said, Rex vs Spino is dead. There's no other way of saying it. Team Rex and Spino would not give up on their theories (no matter how crazy), so we stopped discussing it.

Okay, im almost to my breaking point, Godzillasaurus. And after what you just said about my comment just brought it much closer. That is NOT a fact by any means, that is your opinion. I state the obvious things a LOT on here but almost nobody believes them because they really cant let go of trex being thier childhood hero. Its a bit like how somebody can have a status they didnt deserve in the first place. People had already made a reputation about trex before spinosaurus ever came into the picture, which wasnt too smart in my eyes. As far as wieght and strength goes, look at some of my previous comments on this discussion and discussions before this one.

I'm sorry S-Rex, but you just brought ME to MY breaking point. Let's get this straight first, EVERYTHING IS OUR GOD DAMNED OPINIONS!!!!!!!!!!!!!!! I can not say this enough, REX VS SPINO IS DEAD, DEAD I TELL YOU! YOU get pissed off at us when we say s*** isn't our opinion, and when people say something negative against Spino! and then YOU turn around and say you are "Stating the obvious," and that we can not "Let go of T-Rex being our childhood hero." "People had already made a reputation about T-Rex before Spinosaurus ever came into the picture, which was not too smart in my eyes." Well guess what? How the F*** were people supposed to know that a 60 foot long predator was going to be discovered years later? When you find a bipedal creature that is forty feet long and upwards of 7 tons, who the F*** expects to find something BIGGER!? You can have your opinions, and we respect that as long as you respect ours. Now then, I know that you HATE Rex, so I'm going to end on this: Just deal with it. More people like Rex, and that may never change, so deal with the fact that people have different opinions than you.

@Spinosaurus Rex. Dude, really? Tyrannosaurus, based on its very wide and heavily-structured rostrum and robust spike-like dentition implies that it was designed for crushing and causing massive vertebral damage on impact. Spinosaurus was not designed for this killing strategy but rather precise biting and/or head shaking. Spinosaurus was not designed to crush thick skeletal structures, as its snout was thin by comparison and was clearly designed to snatch large fish from the water, and its teeth (although very robust and spike-like themselves) were conical and clearly designed to puncture deeply into the hides of other animals. I am a spinosaurus fan myself (it is my favorite dinosaur), but I am by no means a fanboy. I still respect the power of other dinosaurs and in some cases the superior weaponry possessed by them. Spinosaurus was so much larger than tyrannosaurus, but it was certainly nowhere near as heavily built… Come on now; that is not an opinion at all.

Don't bother Godzillasaurus, he won't listen. It's stating that Rex was stronger than Spino, he will see it as biased and BS.

At trexes time, there were not many kinds of dinosaurs discovered yet! Of coure people should have expected something to be even bigger than it, its just that many people are too stupid to look at it that way! Im sorry for snappin at ya, but it was the way you had your wording. Just look back at your wording. I dont think ive ever seen you on this forum, but either way if i have or not, you have to make it sound as if its your opinion. I know i did the same you did and im sorry, ok? Today i just snapped for some reason. Now back to the subject, the reason i think the way i do of spino is because there has only been one skeleton found, partial at that, but it was enough to say it was at least 60 ft. in length. So that led me to believe that there were even bigger ones than that due to only being one skeleton found. Now you are not going to tell me that there werent possibly bigger ones than that for there only being one found right? And you have no idea that trex was more heavily built because again with the partial evidence of spino. Ill explain more of my reasoning in a profile text

I have an opinion of my own regarding the one fossil that was discovered. What I think is that the fossil found was the only one that was heavy enough to survive the Sahara for millions of years, and I believe that Spino averaged at 50-52 feet.

Sands change dude, wind blows at it and someone was fortunate enough to find a skeleton where the wind hand unearthed it, wieght would have little to do with it. Im sorry, it was you that made that comment, i didnt look at who posted it, i just assumed it was godzillasaurus. But im sorry about getting snappy, today has been a little pushy for me for getting ready for Christmas

The first(and only skeleton) of Spinosaurus implied a length of 46-50 ft. Only recently were estimates of 60 ft given!

 

Spino Rex, I've tried being the nice guy. Obviously that ain't gonna work. You wanna play that game? Fine by me! Pretty soon, all hell will break loose!

I will then. Not sure what else to say, notice the sudden comment explosion. I think that my Utahraptor/Spino fight was pretty good.
