Aepyornithomimus was a fast, ostrich-like dinosaur that lived in the desert. It had long legs and a toothless beak, and it used its strong feet to run from predators. This dinosaur is one of the rarest finds from the Djadokhta Formation in Mongolia.1 2

Aepyornithomimus is known from only a single left foot and ankle bones, but it is the best preserved ornithomimid specimen from the Djadokhta Formation.1 2

Its name means 'ostrich mimic from Tögrögiin Shiree' because its foot looks like that of a giant ostrich.1 2

This dinosaur lived about 83 to 72 million years ago during the Late Cretaceous period.3

Aepyornithomimus had a special foot condition called arctometatarsalian, where the middle foot bones are pinched together for speed.1 2

It was one of the few ornithomimosaurs that lived in a dry, sandy desert environment.1 2

The fossil was found in the Central Sayr area of Tögrögiin Shiree, about 50 kilometres northwest of the famous fossil site Bayn Dzak.1 2

?How big was Aepyornithomimus?

Scientists have not found enough bones to know its full size, but it was a medium-sized ornithomimid dinosaur, probably about 3 to 4 metres long, based on related dinosaurs like Gallimimus.4 1

?What did Aepyornithomimus eat?

It had a toothless beak like an ostrich, so it probably ate plants, small animals, and maybe eggs. Scientists think it was an omnivore.4

?Could Aepyornithomimus run fast?

Yes, it had long legs and a special foot structure called arctometatarsalian that pinched the middle foot bones together for speed, so it was probably a fast runner.4 1

?Where did Aepyornithomimus live?

It lived in the Gobi Desert of Mongolia about 75 million years ago, in a dry, sandy desert environment called the Djadokhta Formation.4 1
