Archaeornithomimus is one of the largest known ornithomimosaurian theropod dinosaurs. It was discovered from dig sites in China. Its name means 'ancient bird mimic'. They were likely to have been omnivorous, but also prey animals for larger carnivores.
The first Archaeornithomimus fossils were excavated from the Iren Dabasu Formation in Inner Mongolia in 1923. In 1920, some earlier fossil finds were reclassified to a new Archaeornithomimus species. These fossils originated from the Arundel Formation in Maryland.
The Iren Dabasu Formation was believed to have been a humid environment.
