Was T-Rex the fastest predator of all time ?

although just thinking of it the sheer size of the muscles of the legs and overall height and the energy it needs to support energy on those muscles the t-rex must eat what 10 x a day??? it can't be stealthy because its big and it can't run that long fatigue.....and i agree with el too he's not to good with basketball...

These assessments change every day... paleontology in general is very flimsy mainly because we can only work from a few bones here and there That's why I say, imagine viz. The world was a lot different in those days No one really KNOWS what it LOOKED like, only what was there, through scientific analysis and years of research in the field. Think about how life would be now, if that meteor(If that's what really happened to killl off those pesky dinos) didn't strike the earth!! We'd be competely different wouldn't we? Wow, I think my imagination is running away with me.

I have never been able to work out, in my mind, how this thing was efficient at life in general. It's seemingly poorly balanced, 7 TONS (how can a 7 ton animal be THAT fast?), and if it fell over, how the heck could it right itself with those silly little arms? I'd like scientists to work that out.

this couldn't make more perfect sense

I'd like scientists to work that out. The whole idea with the tail has always been that it's a counter weight for balance. Perhaps Rex was actually balanced well enough that getting up is merely a matter of rolling to its feet and dead lifting its body weight with those massive legs? i would think a slight rotation at the hips making it...

Last article I remember reading about the T-Rex was that they thought it was a scavenger, so why would it need to run fast to scavenge? Apparently it wasn't running down prey as previously thought. Also I thought they said the T-Rex wasn't the biggest either? Don't know what to believe anymore

Isnt Spinosaurus the largest carnivorous theropod? As far as we know. And Giganotosaurus and Carcharodontosaurus, among others, were bigger than T. rex too. Pedants 1, Telegraph 0.

Why won't they just let the big guy rest in peace! Ok, think about this for a second, would T-rex have been able to Swim with its tail, like a crocodile? The reason why I say is, in my mind, I'm picturing its suroundings and I'm seeing water and swamps, thick jungle and open planes, mountains and lava activity. Imagine the sheer size of the trees, natural lakes unspoilt and thriving with life fighting to survive. So maybe we could find old Rex stalking a gigantic brontiosaurus catching A drink at the watering hole. ;-) I'm picturing Godzilla (the modern one) while reading that.

They may have been fast, but they certainly lacked in other areas.
