Spino vs T-rex, who would ACTUALLY win?

[GojiraGuy1954]

Not literally holding. No in a fictionalized death battle Tyrannosaurus would almost certainly win by charging through, tanking any attacks severe or otherwise and finishing Spinosaurus off up close fairly easily.

But more realistically, assuming they were to encounter one another in the wild and have long term stakes to making bad engagements, Spinosaurus would have a tactical advantage due to its superior reach. Picture a goose and an eagle fighting on the ground, doesn't matter how much stronger the eagle is if it can't get in close enough for a solid attack without being subjected to a flurry of counters.

Both of those are lightweights

Nonsense. Damage is damage. There is a fossil of an Acrocanthosaurus that died due to complications from injuries from a crocodile, like, a modern sized crocodile.

Ehm...

The tooth had been overgrown by a thin layer of bone, suggesting that the event that embedded the tooth took place long before the death of this animal

I dunno, Spinosaurus would certainly have the advantage in a realistic encounter, but Tyrannosaurus would win in a goofy fabricated deathmatch scenario.

Realistically, Spinosaurus has that long neck, it could just hunker down and prod at any attacking large theropods to keep them at bay. Tyrannosaurus isn't going to finish that off without pushing through those attacks and taking the brunt unless it catches Spinosaurus completely off guard or the two are forcibly pushed together.

Spino has a weak jaw and teeth unsuited for doing any damage to megatheropods

Nonsense. Damage is damage. There is a fossil of an Acrocanthosaurus that died due to complications from injuries from a crocodile, like, a modern sized crocodile. If it breaks skin an animal is going to try to stay clear. Those long jaws would place an awful lot of holes across a large area. Plus Spinosaurus doesn't need its bite to kill an attacker, only to keep it at bay or to hold it within range of the forelimbs.

also that's cap

As far as I recall, there is some discussion if the mutilation happened pre- or postmortem.

An animal is not going to deliberately move into range of the incoming attacks of another animal in order to finish it off unless it's in a movie. It would circle and try to find a safe point to advance where it's out of reach, which is something hard to do when the target has longer reach than you do.

Doesn't matter if Tyrannosaurus could kill Spinosaurus, a real animal is not going to push headlong into a fight that it will definitely be hurt from. Spinosaurus is in a position to stall the fight indefinitely until Tyrannosaurus moves on.

Fox, then. Or raccoon, or badger.

And dogs can be plenty vicious, even more vicious than equivalent wild animals due to having been bred for heightened territorial aggression.

[Bread]

I think we are forgetting that bipedal and quadrupedal Spinosaurus is debatable still, although I do favor the bipedal, I can't deny that it is still an ongoing discussion. So if it really is quadrupedal, Spinosaurus is going to have a tough time with Tyrannosaurus' height.

Anyways, I think the comparison of a flying animal vs. land animal is kind of incomparable to two land animals (or semi-aquatic as a matter of fact). Of course a Swan, capable of flying is going to have the upper hand on a dog. The closest comparison I can think of is a Hippo against an Elephant (Asian or African), but still I don't really think that comparison works.

[stargatedalek]

Again, I'm talking about a realistic encounter, not a fictionalized death battle.

Swans don't fly and swoop in like Rodan when fighting off aggressors, they generally just attack them on foot. If the swan is going to fly it might as well just leave. My point was that the argument weight would be a serious tell of strength is laughable when swans regularly body dogs and other terrestrial predators far heavier than they are.

Spinosaurus versus Tyrannosaurus is more like a jaguar versus a large caiman, if that caiman had a neck half the length of its body that could turn back to cover its own shoulders. No where safe to grab for near the front, long tail in the back, forelimb claws in the middle. So, perhaps more a jaguar and an anteater...

All smaller than an average swan i believe

You're seriously overestimating the length and flexibility of Spinosaurus' neck.

[stargatedalek]

Smaller =/= lighter. All of those animals are heavier, some far heavier, than a swan. Which is what you said made Tyrannosaurus inherently stronger than Spinosaurus. Spinosaurus is larger but not as heavy, Tyrannosaurus is heavier but smaller. Ergo weight =/= stronger animal.

And again, you're refusing to acknowledge the claws. Why would a predator do something so stupid as to rush headlong into that? If Tyrannosaurus didn't catch Spinosaurus completely off guard and somehow get close enough to bite the neck without being noticed (which would not even be a fight) it wouldn't be able to get in close enough to do serious damage without getting gutted.

Tyrannosaurus moves in, Spinosaurus pulls neck up and out of reach unless Tyrannosaurus gets close enough for Spinosaurus to use claws. Tyrannosaurus paces around, Spinosaurus only needs to swivel to keep its jaws between Tyrannosaurus and its own neck.

If you really demand a "heavyweight terrestrial animal" analogy. Jaguars and anteaters. Look up who wins and spoilers it's not the one with the higher weight or stronger bite.

[Bread]

Is it possible for a Spinosaurus to move its arms in a flexible and quick maneuver to cover all angles of its body?

I have to agree with @GojiraGuy1954 on the overestimated flexibility of the neck. Sure a Tyrannosaurus is probably the lesser of the two to have any flexibility in the neck, but I doubt a Spinosaurus could pull off quick turning maneuvers of its own.

I also think we are forgetting the spine of Spinosaurus, as well as the ability of both of these animals to easily fall over and possibly fatally injure themselves.

Size is mass and mass is weight. Length does not mean an animal is bigger.
I.e. a dog is bigger than most snakes

>you're refusing to acknowledge the claws
Spino would have to rear up to use its claws to fight a megatheropod in any real capacity. Which would open up the underbelly and neck to the Tyrannosaurus.
Spinosaurus claws were also not designed to cleave up megatheropods. To me it seems like you've been watching too much "Monsters Resurrected."
Anteaters are very nimble, much more than they seem, and can jump quickly to defend against jaguars. Spinosaurus is an aquatic animal. It would not turn fast on land.

[Lynx]

Anteaters can jump? Wow, the more you know.
