T-Rex/Spinosaurus comparison

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.

MrHappy is right. And also, why are so many people coming back to these older posts?

No idea. Probably because these are the first ones that appear.

Perhaps that's it.

I like this! I'm a Spino fan but I find this list very accurate.

Thank you, for both agreeing with this list, and not stating any opinion on which would win.
