I was thinking about one thing. We now know that T-Rex was the biggest carnivore in terms of mass and height that ever lived. Spinosaurus was slightly longer but not as tall and much more lightly built than T-Rex. We have found around 50 T-Rex skeletons. If all humans died out. and another species came along and dug us up what would the odds be that they would discover one of the biggest human skeletons to ever walked the earth? The chances are slim, zero to none. Sue is the biggest skeleton we have from a T-Rex but the thing is, she is probably an average T-Rex that just had the opportunity to reach full adult. Many of the other T-Rex skeletons out there were considerably younger than Sue when they died. And those who were not younger, like Trix and Scotty amongst a few others, are almost identical to Sue in size. Just imagine how many Rexes there have been walking the earth during a span of 3-5 million years. Based on that evidence there is nothing that suggests Sue is anything exceptional for a T-Rex. She just reached her full size. she was 12.3m/41ft long. about 4m/13ft tall at the head and is believed to have weight around 9 tons. Taking this into consideration there is no question that in some cases there would have been T-Rexes walking this earth being over 13m/43ft long. 4,5/15-16ft tall and hovering at around 10 tons. Can you imagine what kind of animal this was? It also had the smell of 100 bloodhound's combined. Its eyesight was so good that it could see preys 6 kilometers away. And it's binocular range was greater than that of a Hawk. And then it's always the bite force. Estimated to be around 4-5 tons in sheer force. This is the most Apex predator to ever exist on our planet. For us a big dog is a very strong and dangerous animal, not to talk about a Tiger, for example, they are one of the most dangerous animals today and will tear us to pieces without even trying. Weighing in at 300kg. 3m/9ft long and has a bite force of around 1000 PSI. That's 70kg... That put things into perspective when you compare the two. I really don't think people realize what kind of
an animal T-Rex truly was.

While I agree that we currently don't know how big the largest T.rex was, I doubt it would have gotten much longer or heavier than Sue.
Sue and Trix were mature adults at the time of their deaths. If they lived longer, they probably didn't put on much more mass, and didn't get much longer. Their days of rapid growth were over. Birds don't grow much more once they become fully-grown, and the growth rates of crocodilians slow down exponentially the older they get (ex. no 14 foot, 1000 lb 40 year old saltwater crocodile is going to grow to 16 feet in another 20 years, and gain another half-ton during the same time interval).
I admire your fascination with T.rex, but it's important to temper expectations when making educated guesses.
Do you believe that we essentially have found the biggest T-Rex that ever walked the earth in a span of maybe 5 million years despite the fact that we only have around 50 skeletons? The odds on that are astronomical and the fact that we have found specimens like Trix and Scotty that are almost the same size indicates that even if they were indeed fully grown, they were not extremely large for their sort. Probably average fully grown. How many that reached that age and size is another question however. But we have found parts from some specimens that suggests they were even bigger than Sue but they are way to incomplete to know for sure. And i mean i'm only talking about a specimen that would in this case be 0.7m longer, 0.5m taller and 1 ton heavier than Sue. I don't think that's impossible at all.
