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.

Like your comparison. It's pretty accurate.

Thanks. The true test is to see if S-Rex likes this. Nothing against him or anything, just the way he is.

I hate to say it like this, but I think it may be a little dangerous to put one is bigger than the other. Just sayin. Other than that, not bad. I would have mentioned pack behavior for Tyrannosaurus. I'm not sure if either were necessarily slow. Both could probably hit 15-25 miles per hour. It was a good idea not to put specific sizes. Not bad.

The Spino being bigger than Rex is for height and length (confirmed). Weight and strength is unconfirmed, but it is believed Rex is stronger, while Spino is heavier. That sound better?

I suppose. I'm not trying to sound picky or biased, but Spino seems relatively light weight for it's overall size, kind of like Diplodocus. Rex seems very heavily muscled and heavily built, therefore, maybe, I do stress maybe, heavier. Just my thoughts. Nothing new, just pointing it out. Spino was certainly longer, it's head height may have been the same as Tyrannosaurus, but with the sail, it would have added another 2 ft or so.

I almost forgot, the fact that Tyrannosaurus had an infectious bite. May seem minor, but in my opinion, is pretty important and should be pointed out.

I know this stuff (not major, just didn't include because then more people are happy). I do see what you mean though.

Let's see if a Rex fan can make the Spino fans happy. Spino was also pretty unique with it's long jaws. Sure other spinosaurs had similar jaws, but that's one of the first things I think of when I think of Spinosaurus, it's jaws! Right behind the sail of course.

When I think Spinosaurus, I think long jaws, big sail, big arms, and swimming. When I think T-Rex, I think king of the dinosaurs, tiny arms, big head, big teeth. They are both unique in their own way, but Spino is more unique.

I just dont understand why some scientists say that trex is likely stronger in comparison, i truly dont. And its sail, if it falls on it and only breaks a higher part of it, i dont think it would likely affect it, but if it were really close to the bottom of it, it would either be critically injured or die. Why arent you listing that it dosent have good sense of smell or intelligence? It had to find food too you know and not just by sight. It also had to be preety smart to find where the fish are in the water and also how to outsmart thier larger prey. But other than that, it seems preety legit and accurate.

Alright Spino Rex, you made your point.

I guess what I was doing was comparing them only listing what one had over the other. Not saying Spino is stupid (for a dinosaur), but Rex, with the millions of years of evolution, was likely smarter. Because Rex was likely an active hunter (and the evolution), it probably had a better sense of smell, so didn't mention for Spino. This is what the comment section is for, isn't it?

you know, Spinosaurus could have been an active hunter too, not being rude or anything.

Lord Vader

MemberTyrannosaurus RexJun-20-2013 9:21 PM
As for stronger, I guess it is because they have found holes in bones from a Rex bite that are bigger than a Spino tooth is (deeper and wider). This seem legit to you? Am I exaggerating?

I know it could have been an active hunter too. Not trying to sound rude in my last post. I think Spino has a fisher's build to it though. I think the nostrils are high up on the skull so it could remain almost completely submerged. As far as it being an active hunter, I think it would be much like any other carnivore, the old, the sick, the young, and probably anything significantly smaller.

Thats just the bite, im talking about its body build.

Lord Vader

MemberTyrannosaurus RexJun-20-2013 9:29 PM
The body build huh? I'm pretty sure that Rex had extra ribs that go to the hip area for extra protection, not sure about Spino. The claws could inflict one heck a scratch. It just looks a little slimmer than Rex in pictures too though. I personally think that Rex was a bit more heavily muscled than Spino.

MemberCompsognathusJun-21-2013 3:31 PM
I agree with ya MrHappy. I am pretty sure that Tyrannosaurus did have extra ribs for one thing. Spino was almost certainly slimmer overall. That's one reason why I think it was relativity light weight. Did not have the overall muscle mass of other large theropods.

Thing is though, Spino didn't need to be as muscled as other large theropods. Spino may have hunted sometimes, but it would go for anything small or weak (like any other theropod given the choice), but had the extra ability to catch fish if land animals were scarce.

MemberCompsognathusJun-24-2013 12:10 PM
Why do you say that ? To me, Spinosaurus probably had to be more muscled than other theropods, my reason being, it swam a lot, which had to give it a lot of exercise, it had to drag huge fish out of the water, had to be able to stand up against other predators, like the ones i mentioned in my last discussion ( Sarchosuchus, Charcarodontosaurus, and Rugops ) And in my opinion, it must have hunted larger dinosaurs too. So, to me, it must have had just as much or more muscle than other Theropods.

Lord Vader

MemberTyrannosaurus RexJun-24-2013 2:51 PM
We may never know how heavily muscled any dinosaur is. For all we know, Spino might not have even eaten fish. Scientists believe Spino was a fish eater because of fish scales found in a Baryonyx fossil. Swimming would be great exercise, but it likely would not have gone past knee deep most of the time. Dragging huge fish out is where Spino would have to work at it. If Spino did hunt large prey, it would likely do what any other predator would do and go for the stragglers. I think Spino would have intimidated it's opponents more often than not. If it did get into a fight, it would slash it's opponent (this is where dragging large fish out of the water would help). Spino was probably heavy muscled, but maybe not as muscled compared to other theropods pound for pound. I hope you agree with this answer. Great question, I really had to think about my answer.

Also, as far as how strong Tyrannosaurus was, it was not just strong when it comes to it's bite force and neck muscles. It's leg design suggests that it could walk long distances in search of prey, territory, etc. Great exercise right there. It would have very strong leg muscles along with it's jaws and neck.

As far as competition for T-rex goes, sure it did not have much. The only thing a Tyrannosaurus would fear, would be a larger Tyrannosaurus. Now, the reason why T-rex had no competition may be because nothing could compete with it. No other predator of similar size, could survive. It seems when the tyrannosaurs moved into a new location, they drove everything else out. They migrated to N. America from Asia at about the same time predators like Acrocanthosaurus died out. Coincidence? I don't think so. Once the big tyrannosaurs, Daspletosaurus, Albertosaurus, etc, showed up and then later Tyrannosaurus, nothing could compete with them.

Spinosaurus and T. Rex are two very different animals. Spinosaurus Aegypticus had a very frightening and intimidating appearance by dinosaur standards, but Tyrannosaurs had more complex brains, because they are later than Spinosaurus Aegypticus. In many circumstances the two would avoid each other. I find it unlikely that they would fight each other.

MemberCompsognathusJun-24-2013 8:11 PM
I have that same thought. In the end, it often comes down to intimidation. Or they would not be sure if the other was prey or a rival. Because their diets were probably different, they would probably ignore one another.

They all would get exercise somehow. All dinosaurs walked around, they didn't go to a prehistoric fast-food restaurant and sit on couches all day. Spino would swim, Rex would walk for hours on end. They would likely ignore each other due do differences in diet, but in desparate times, they would likely fight for anything and everything. For the most part though, they would likely leave each other alone.

T-Rex would have trouble getting up if it fell because of it's small arms but I don't think it would die from it unless another T-Rex or carnivore was involved. Other than that, it's a reasonable comparison between the two.
