This is a mismatch in favor of Giganotosaurus. Except if you believe Andesaurus to be 30 m long.

paralatitan vs 3 spinosaurus


Is there any evidence of cooperative hunting by Spinosaurus?

If 4 is amismatch, what would be a fair number?

1 vs 1 would be fair, because:
http://paleoking.blogspot.de/2012/06/forgotten-giants-3-andesaurus.html

That's right, you heard me. DEAD wrong. Andesaurus isn't 100 feet long. Not even close. That length has been repeated in many places, Wikipedia among them (at least a few months ago). I don't know how many people have actually read the scientific literature on Andesaurus (which now includes the description paper, Calvo & Bonaparte 1991; the titanosaur comparative anatomy paper Salgado et. al. 1997; and an extensive redescription, Mannion & Calvo, 2011). And the number of people who have actually seen and measured the fossils, I could probably count on my hand. The dorsal vertebrae (what's known of them anyway) are absolutely dwarfed by those of Argentinosaurus - a bit odd for two creatures that were supposedly around the same size. Even plain old Brachiosaurus has bigger dorsals. Andesaurus is a lot smaller than we've been led to believe.

Another quote:
Even the length of the torso is uncertain, since the anterior dorsals are missing. Indeed, it may have been only 50-60 feet long. 65 is a stretch.

He thinks 15-18 m is a good range. Therefore, 1 vs 1 should be O.K., as this Sauropod is not that much larger (15-18 m vs 12-13 m).

^C. saharicus was probably in the same weight range as T. rex specimen Sue, i.e. 7-9 tonnes, versus Nima Sassani's ~63 tonne estimate for Paralititan.
Having said that, C. saharicus was probably tall enough to reach vital areas (comparative image in progress).

No, but his relative Mapusaurus seems to have hunted in groups. So it is possible that Carcharodontosaurus did.

There is none against it, and indication in some related taxa. If we exclude this, that would be like saying it wasn't feathered.

Most of our fight scenarios are merely hypothetical, why is it a problem to speculate a bit on cooperative hunting? A fight like T. rex vs Giganotosaurus could have never happened, while there is a very good chance that C. saharicus and other theropods were a cooperative hunters.

Yes, thats a could of. But relatives often dont replicate behaviours. Panthera leo is a cooperative hunter, Panthera tigris was not.
Would you like to paralititan v 5 Mapusaurus instead?

Well, its a lot safer to assume that both T.rex and Giganotosaurus were able to fight, than it is to assume they cooperatively fought.
If you wish to grant species of animals capabilities that there is no evidence of, please do so HERE.

what about time-traveling, isn't that a rather unlikely capability for a theropod? At least it is not seen in extant ones, jsut like extant ones are mostly social animals and we are for some reason automatically assuming extinct ones weren't.

For all animals actually. We however should focus on animals known physical characteristics and behaviours, before inventing them, or assuming they might of had them.

No sorry, we rely on evidence before conferring characteristics to animals in matchups. If you are not happy with that, you are free to use the Fantasy Face-off part of the forum, and grant animals what ever characteristics you wish. Have fun!
