What are the two front legs for?
If the ratios in the popular diagrams of a T-rex are correct, they cannot make a T-Rex eat anything. And if the creature walks the way they are drawn, they effectively cannot be used to hunt and grab things either.
It must be a crawler, instead of a creature that stands up and walks upright. The head on the T-Rex is too heavy and large in proportion to the body for it to be walking upright for too long. It must be weighed down. The front two legs are for lifting the body in the center off the ground. And the back/bottom legs make it good walking forward rapidly.
Unpopular opinion: It is an oversized iguana-like reptile. A heavy head, with small front legs and oversized large back legs.
- kadoban 3y agoThe front apendages are far too small for that to make any sense. Just compare iguana front legs with T-rex arms, proportional to their body size. And that's ignoring square-cube law scaling difficulties that would make it even worse. Those things would snap like twigs trying to hold up that body.

- HarHarVeryFunny 3y agoEvolution - T.Rex with it's upright stance evolved out of earlier animals that walked on four legs. The small size of the arms of most (but not all) species in this family of animals tells you that the arms were not normally used. Some snakes (also having evolved from animals with legs) still have vestigial legs - all but disappeared since they too serve no purpose.
- projektfu 3y agoThere has got to be some comparison to ostriches, giant moas and Phorusracids, where the pectoral appendages are absent or vestigial. They're all theropods as well.
