So how do you want SOME DINOSAURS!
XD and not just any dinosaur.
G.carolini here to pwn all you T.rex fanboys ^^
Ok, this are my arguments. Because people is very into this T.rex vs C.carolini thing.. but I'm too lazy, so I'm just copy pasting what I written on a forum:
-A meter or two in lenght makes a whole lot of additional body mass when projected into three dimensions.
-Giganoto's skull is 1.92 cm, Rex's is 1.45. Giganoto's is significantly larger.
-Even when T.rex's head seems more hevily built for it's size, remember than strong jaws and blunter teeth are often a trait of scavengers to intimidate and crush bones. (Such as bear and hyenas) Giganoto's more aerodinamic, gracefull and... sharper design lines are the trait of the predator. For much the same reason ninjas don't tend to wield maces, the longer, sharper and seemightly weaker weapons of G.carolini seem more apropiate to strike fast and deep into the bulnerable areas of prey to kill it as fast and efficiently as possible. The crushing and chewing prowess T.rex supporters mention so often are more useful once the target is dead than to actually kill it.
Other than that, I think all the T.rex supporters are far too influenced by the awesome name, all the movies featuring the animal over so many more years, patriotism, you name it, over cold logic and the simple idea that Giganotosaurus just really seems to have been a larger, more dangerous animal
Yea that's right to fricking sauropods (replting to someone who said G.carolini was only dangerous to sauropods :/). Because everybody knows only pussified dinosaurs would hunt the largest animals to ever walk the fricking universe as we know it, way softer than an elephant sized ostrich with bad teeth.
Which gets me to my next point.
Think about their abailable prey.
Were at the time and place tyrannosaurus lived herbivores larger than itself or even of his own size? the ornitischians herbivores that roamed Laurasia back then were hardly near as big as Rex himself, whereas Gondwana's landscape was dominated at the time by the largest herbivores to ever live, the Titanosauroidea, some of them 10 times larger than Giganotosurus.
A regular T.rex might have never seen anything even slightly larger than itself (a female maybe, which would be a chance to make love, not war) and would proabably run shitless if it did.
So all in all, this are not very anatomically different animals any slight advantage is rather subjective, but if they'd meet they would probably think of each other as belonging to their own kind, which is after all the only similar thing they have seen. So, what fallows would be what usually heppens when 2 animals of the same type meet if one is one is larger than the other (Don't even twice as larger, just noticeably larger or bulkier)
T woul say to himself "That is one large and ugly guy, better do not mess with.. not worth it"
And G would say: "Gimme your lunch money, twerp"
