主要差异
- Gallimimus (6 m, ~440 kg) was roughly twice the size of Ornithomimus (3.8 m, ~170 kg), but both were ornithomimosaurs.
- Both had toothless beaks, long necks, and ostrich-like body plans adapted for speed and omnivory.
- Ornithomimus adults had feathered wing-like arm structures for display or brooding; Gallimimus feathering details are less certain.
- Gallimimus lived in the Gobi Desert of Mongolia; Ornithomimus lived in Late Cretaceous North America.
- Gallimimus is featured in the iconic herd-running scene in Jurassic Park, which accurately depicts its speed.
