Orcinus orca vs. Tyrannosaurus rex (both in their element)

[Infinity Blade]

^Which is rather why I didn't allow it to go above the tyrannosaur. I honestly thought allowing it to go above as high as it pleased to essentially go all eagle on the T.rex would be quite unfair.

[Spider Horse]

Then the reptile would be victorious.

I wonder if the orca could outflank the T. rex and bite its legs, crippling it from behind...

Orca whales can swim 29 miles per hour, even if the Orca can't go above the tyrannosaur, it could just swim to the other side of the terrain and ram into the tyrannosaur, at this point, the Orca is just a giant, 5-ton living missile that can move 29 miles per hour.

I vote for the Orca. This doesn't even need to get down to jaw power. If you were a 7-ton bipedal terrestrial animal, and a 5 ton projectile rams into you at 29mph, what do you think is going to happen?

I'd have to agree with this especially since ramming is a normal behavior for an orca.
Seriously wouldn't it be all to easy for the orca to knock the dinosaur over?

The impact would probably kill both animals. The trex would have a crushed ribcage and the orca would have a fractured skull.

[theropod]

Orcas use ramming to kill other whales of equal or larger size, their skulls seem up to the task of resisting the impacts.

That would be a legit point if this were an animal not adapted for ramming, e.g. in one of the cases where people came up with the idea that T. rex would ram an opponent.

[Deleted]

Except that the Tyrannosaurus may probably be multiple times stronger than the orca.

[theropod]

Doubtful at best. Being larger it will be somewhat stronger of course, but that as a terrestrial animal it can produce more thrust (I’m sure the reverse situation would result if you estimated the thrust it could produce in water) doesn’t translate to overall body strength.
In any case, that has nothing to do with whether the orca’s skull would fracture. It doesn’t do that when ramming a minke whale, I don’t see why ramming a (more gracile!) theropod should make it break its skull.

At full speed like he suggested? Besides, I haven't actually seen any evidence of dolphins or orcas killing similar sized animals with blunt trauma.

Tyrannosaurus might have been more gracile but it's still larger. Charging into a larger solid object at full speed does not bode well for your health.

The Orca doesn't even have to it at full speed, it only has to do it with enough force to knock the dinosaur over and the fight is essentially won.

[Cross]

Even if the Orca doesn't cruise at full speed like I suggested, say it only went 16-20mph, a 5-ton animal ramming into you at that speed would knock you over, fracture your ribcage, and you're as good as dead.

[Infinity Blade]

We should remember that the orca's ramming attempts are really, for all intents and purposes, just another charge. I don't think it's unreasonable to say a T.rex could simply side step the orca's charge (and btw, I've shown countless times that theropods were not stiff rods). And after that's been done, the orca's momentum from its charge would make it hard to abruptly stop after it misses, leaving it vulnerable to get attacked by the tyrannosaur.

[creature386]

^Depending on how fast the orca rushes, counterattacking is easier said than done. Though it probably won't be able to accelerate that fast if we assume close combat. On the other hand, slower movement would make counterattacking easier. T. rex surely was no stiff rod, but still a bit disadvantaged compared to a marine animal as they can simply far easier turn at such great sizes.

[Infinity Blade]

^It's not counterattacking first. It's simply side-stepping the orca that's trying to ram it from a distance. It only attacks the orca after the latter misses and is struggling against the momentum of its own charge (oh and correct me if I'm wrong, but wouldn't the orca's enormous size also make its momentum after missing even harder to recover from?).

Close combat? That wouldn't really leave much room for the orca to gain the speed for ramming now would it? It would turn into a biting and strength contest, and it appears that the tyrannosaurid would prevail given its larger size (on average at least) and its more impressive skull/jaws.

I also brought up the fact that theropods weren't anywhere near as unagile as often believed in order to point out that Tyrannosaurus wouldn't be too unagile to evade a ramming attempt (kind of an inb4 sort of thing), not to make a debate in regards to who has the agility advantage.

[creature386]

You're right about the close combat part, I was trying to compare the different possibilities since starting positions are never given in such battles.

And thanks for the clarification, I now understand your point a lot better. Though dodging can also be quite hard if the attack is fast.
