It was a six-ton meat-eater with a head the size of a steam shovel and a
mouthful of teeth six inches long, a truly fearsome beast. But the legend
of Tyrannosaurus rex rampaging along like a prehistoric SUV appears to be
incorrect. New research suggests that T. rex just didn't have the legs.
"Their anatomy says they can run," said Baltimore-based paleontologist and
artist Greg Paul. "They look like giant birds, and birds can run fast.
Elephants can't run" because "they have immobile ankles. T. rex of all
types have bird-like feet."
Paul said he is not convinced by the "incredible values" in the
Hutchinson-Garcia calculations, suggesting that anatomy is a speed
determinant, not simply body size. "This area is still very controversial
and will take a lot more work," he said.
