it was at those point declined that dinosaurs above 20 tons or something like this could be warm-blooded, because amount of heat that ehy would need to generate at their size would sort of burn them from inside,
Paulwhale, I present to you Balaenoptera musculus....the largest known animal to ever inhabit the earth. Male specimens weigh approximately 100 tonnes. Females closer to 150. They are somewhere in the region of 90-100 feet long.
I shall conclude our fun, fact finding mission by stating that it is, in fact, warmblooded. As all mammals are. When next you argue, I suggest you think first.

About my age, I may be older than you, but mistakes you saw are due the fact that I'm not native english speaker, I'm from Russia, that's why you spotted some mistakes.
I still do have concerns about anyone over the age of thirteen starting a topic such as this, but we shall see...however, that didn't answer the question.

I personally saw a vide of crocodile that weighed around 500 kg killed by a FEMALE tiger of about 140-150 kg
There are a number of reasons why this is irrelevant....
The first being that crocodiles are not only cold blooded, but there has never been any dispute as to whether or not it is. They spend hours at a time sunning themselves in order to simply get on with their way...the debate, however, remains when concerning dinosaurs.
Second of all, a tiger is a predator, and is armed and evolved to the specific end of killing animals far larger than itself. A mammoth is not. A mammoth is a large herbivore, armed only with its (normally) superior size...an advantage it would lose in the encounter you propose.

the main disadvantage of a dinosaur would be his cold-bloodeness if they would fight in a cold tempereture area, I don't know how to state it easier for you, man, honestly, you don't understand something? or what? it WAS cold blooded, it therefore would not be able to move even at very slow speed, I know what are you gonna say: you don't need to run in the fight, but in this fight you do, because look:
they meet each other face to face, dinosaur tried to stomp mammoth, but mammoth easily runs a bit around dinosaur and gets to it's side (dude to cold weather dinosaur will not be able to even turn around quick enough to still stand face to face with mammoth) and when it is near dino's side, dinosaur allready can't do anything about this, it is all done, mammoth is at dinosaur's side, dinosaur tries to stomp it by moving his legs to the side and trying to sidewalk? it collapses, dinosaur tries to turn around? he can't, because mammoth is faster, and dino is not mobile at cold weather, and mammoth keeps staying at dino's side and goring him with tusks, though I think one hit with tusks coming through all inner organs and nearly coming out from other side wil be enough for dinosaur to die later simply of blood loss, do you think all these maneovers are impossible? I don't think so, I know it looks kind of too difficult for mammoth to perform, but mammoth was smartest mammal to ever walk the earth (except man), it had largest brain of all land mammals (though hornless rhino was bigger overall but had smaller head), elephants have been seen doing really smart things in a fights with rhinos, things like coming a bit far from rhino to force it to charge, then dodge the charge and come ti rhino's side ang gore him with tusks, this involves some maneovurs, I heard of it from zookeeper, he said that when elephants want to mate, they walk around and look for female, but from afar he saw rhino, elephant, having bad vision, does not recognize that it is rhino, thinks it is female elephant, and comes closer, then it sees it is rhino and gets angry and attacks, they start to fight, elephant tries to gore rhino's side, as you probably know rhino's style of attack is a bit different, he charges at anything and then tries to deliver blows with front legs, teeth and horn, but elephant manipulated with horns so good, that rhino never even made contact with elephant body, while elephant was trying to make rhino charge, to apply this strategy: dodge the charge and gore the side of rhino with tusks, and he finally did it, same thing here, with the exception that here mammoth would have to dodge animal that moves very very slowly, due to it's size and tempereture, I think mammoth would win, but you are right, it is very unlikely that either of animals would even attack each other, but if they would, I think mamoth would do it because he was more maneouverable(sorry for spelling) and smarter (look at the pic I gave, mammoth's head was larger, and his overall brain to body proportion was prety big, which meant his brain was pretty big for his body), and of course MUCH quicker, a lot quicker, and finally he had a weapon with which he could do deadly damage to even such a creature like 100 tons dinosaur (it's body was about 5-6 meters thick, while let's say, ok mammoth had undeveloped tusks of 4 meters, they would be not bended then, hehehe, and still imagine that something gores your body to nearly a half of it's thikness,, you would die of course due to blood loss) think about it, man, just think about it, dinosaur is very slow, it's body is positioned not very high (unlike on those laughable picture), it would be gored pretty easily, just think about it, it is not as if you fought a guy who is 5 times smaller than you, because you are not that big to experience any difficulties moving, but argentinosaurus was on the edge of size (it was as large as a terrastrial creature can ever get), it had difficulties moving in warm tempereture, it would be almost immobile in cold tempereture.
I willexplain you even simpler, THERE IS NO DEBATE WHETHER ARGENTINOSAURUS OR OTHER BIG DINOS WERE WARM-BLOODED, THEY WERE COLD-BLOODED, THOERY INVOLVED ONLY SMALL ONES LIKE T-REX, is it simple enough now? ask scientists if you don't belive me.
You just lack some really obvious facts, that's why you are so sure argentinosaurus would win, but it depends where they would fight.
LOL, it lives in water(Balaenoptra musculus), I suggest YOU think first before you argue.
