Tyrannosaurus rex may have been much larger than previously thought

We may have yet to discover the fossil remains of some of the largest examples of the species.
Tyrannosaurus rex - arguably the poster child of the dinosaur world - certainly needs no introduction.

Sporting rows of razor sharp teeth, this enormous land-dwelling carnivore was one of the most fearsome predators ever to walk the face of the Earth.

According to some scientists, however, the Tyrannosaurus rex specimens we have found to date do not fully reflect the maximum size that these huge reptiles might have actually reached.

The largest individuals may have been 70% heavier and 25% longer than anything we've seen so far.
"[We] really have no idea from the fossil record about the absolute sizes they might have reached," said Dr Jordan Mallon of the Canadian Museum of Nature in Ottawa.

"It's fun to think about a 15 tonne T. rex, but the implications are also interesting from a biomechanical or ecological perspective."

Actually finding an example of such a gargantuan Tyrannosaurus rex, however, would be challenging.

Due to how rare these fossils are and how infrequently they are found, it could take another 1,000 years of digging up bones to actually find a specimen within the 99th percentile of size.

What it would have been like to meet such an animal face to face, we can only imagine.

Alligators are a strange choice in model for a therapod.

I suppose planetary conditions on earth were a bit different which allowed for such a massive creature; one article I read said that some T-Rex were up to 33,000 lbs which is roughly 32-33 tonnes. Also, though maybe I am niggling here, but many animals I think were actually larger that what the skeletons in museums depict as you had to make accommodations for things like cartilage, bursa sacs (that fluid filled sac in between joints). Makes me wonder how such a massive creature could even walk let alone run or dash after prey or rivals. Was the gravitational fields a little less intense? Maybe... [More]

All these large animals were "conveniently exterminated" for humanity to strat its journey. Conveniently by God, alien, previous inhabitants remains a mystery.  I can't believe however how pristine and healthy our planet was back then, obviously larger quantities of oxygen and plainly or carbon were mainly the reason everything was huge .

Ummm....what? I honestly can't tell if you are being facetious or not.

Neither do I ?

Let me ask this, are you implying that large prehistoric animals may have been killed off by outside forces i.e non-natural forces? (aliens, Staypufft Marshmallow Man, Elmer Fudd, etc) Because I still cannot figure out if you were joking or not but I am sure you know if you were or were not.

It's a theory out there yes , one I don't necessarily believe to be true but can't dismiss it either as it can be plausible.
