Tyrannosaurus Rex 30% bigger than thought

The massive prehistoric meat-eater would have gained weight twice as fast as previously estimated.
The result was a predator substantially bigger and heavier than ever thought possible. "We knew she was big but the 30 percent increase in her weight was unexpected," said museum exhibit curator Peter Makovicky.
Modeling the teenage growth spurts of an ancient mega-predator was made possible by comparing computer models of smaller, younger Tyrannosaurs with those of full grown adults, including the tyrant lizard queen, SUE, the largest T. rex skeleton yet discovered.

Hmm...Good news.. A 10 tonne T.Rex would be perfect. In that case,Spinosaurus will be twice the size of T.rex. Before it was 3 times bigger than T.Rex.

It is interesting that millions of years ago there were many examples of giant growth in animals and plants. The scientific community never really explained why this growth was possible although there are different theories causing it such as changes in the earth's gravity, the atmosphere or even the rays of the sun. And what about humans? Look up giant skeleton Saudi Arabia on google. We are told by the so called experts on this site that these are phoney made by photoshots but I wonder. Giant animals and giant humans? Their growth could have been affected by the same conditions on the earth.
