主な相違点
- Giganotosaurus (12.5 m, ~6,800 kg) was slightly longer than T. rex (12.3 m, ~8,400 kg) but likely lighter.
- T. rex had a deeper, more robust skull with a stronger bite; Giganotosaurus had a narrower, more elongated skull that could open wider.
- Giganotosaurus lived 30 million years earlier in South America (Late Cretaceous); T. rex lived in North America.
- T. rex had forward-facing eyes giving it excellent binocular vision; Giganotosaurus had more laterally placed eyes.
- Giganotosaurus may have hunted giant sauropods like Argentinosaurus; T. rex preyed on hadrosaurs and ceratopsians.
