Fossil scans reopen debate over T. rex
[News] "ST. LOUIS -- New methods of analyzing fossils have scientists arguing more than ever about whether (T. Rex) Tyrannosaurus rex was a lumbering scavenger or a swift and agile predator.
A CAT scan study of Tyrannosaurus rex skulls shows it had the inner ear of a much smaller, swifter predator. But a close look inside its thigh bone shows it had the ungainly body of a heavier creature.
'I think what we have to do now is re-model dinosaurs,' said Jack Horner of the Museum of the Rockies in Bozeman, Mont."
