T-Rex Bigger and Hungrier Than Previously Thought

gpronger writes "Researchers John Hutchinson (Royal Veterinary College in London) and Peter Makovicky (Field Museum of Natural History, Chicago) built digital models of a T-Rex and then added flesh using the structure of soft tissues in birds and crocodiles as a guide. This allowed them to project body mass. By doing this for a number of specimens of different age and size, they could also evaluate growth. At maximum, the adolescents could add 11 pounds in weight in a single day. The adult was found to be 30% heavier than earlier estimates, at more than 9 tons. With this size and appetite, they would need a large range, and therefore also be relatively rare in the ecosystem of the time."

What? Read the paper. They used the real skeletons (5 of them), not birds or crocodiles, as models.
