@ Spinodont: Tyrannosaurus was fast? Maybe, when compared to other large Theropods, but not when compared when other predators eg. the modern large predators of Africa.

I meant compared to other large predators, ie near its weight.

Tyrannosaurus Rex is a large theropod and the 3rd largest land carnivore ever(smaller than Giganotosaurus and Spinosaurus)T-Rex is the top predator of it's time and the most famous Dinosaur in the world,it had the strongest bite force of any land animals and It's teeth is a biological weapon(T-Rex is the only Dinosaur that used this) it contains bacteria that makes the victim infected,T-Rex is 12.8 m (42 ft) in length, up to 4 metres (13 ft) tall and up to 6.8 metric tons (7.5 short tons).

I'm not really that much of a dino expert, but here's some facts I know.

T-Rex, being top predator of its time and area, would have a very robust body suited for ambushing hadrosaurs (e.g. Edmonotsaurus) or taking the better of fierce herbivores (Triceratops and the like). The Tyrannosaurus is, undoubtedly,(at least I think) the largest carnivore of its type.

I won't deny that T-Rex would be able to run to 40 mph - but for an incredibly short time (perhaps a spilt second) wherein it lunged suddenly at its hapless prey. After that, it would be quite tired, and dinosaurs like that wouldn't like taking long chases at their prey. Also I don't think it's a pack animal, is it?

And, I've read somewhere that females are usually fiercer, larger, and more agressive than males, as with many reptiles.

Even the most stretched out to beyond reality estimates say only 34mph. The most probable estimate would be about 25mph tops. Unless we are talking about young animals. In which case, 40mph isnt that far fetched.

Likely not.

How do i know what? That 40mph is illogical for adults?
Lets see now. Based on slightly old research, Tyrannosaurus would have needed 80% of its muscle mass (40% per leg iirc) to run in excess of 25mph.
There are multiple estimates all around the 18mph mark, and one that goes as low as 11mph. Based on some new research into theropod tails, Tyrannosaurus (and probaly all theropods) were faster than previously thought.
However, Tyrannosaurus didnt have the nervous system that could respond quick enough at speeds over i think it was 18mph (ie, at speeds in excess of that, it could step into a hole and not actually realise straight away).
But as i said, the juveniles had the legs to run with ornithomimids...

Please see my thread about it. I don't think you can really judge that anyway, and you also have to take account that in birds the male often seems to be larger and more aggressive. That part about the female being more aggressive came from BBC. In my opinion, t. rex was kinda like boa constrictors in size+gender dimorphism, with the female being slightly larger but not any more aggressive.

Wait, if I'm correct, first it was 18 mph. Then there was some new research that showed it was lighteer and faster. Lastly, there was the tail placement thingy. And the nervous system part doesn't make any sense to me.

I dont know which ones came first, but i know that the nervous system one and the 'tail placement thingy' are both recent (the latter more so).

Ill try and find the link to the nerve one.
