Scientists have found the remains of ornithomimosaurs, or “bird-mimicking dinosaurs.” Outwardly they resembled ostriches.

The authors of the new study found thatthe fossils likely represent two separate species of ornithomimosaurs. One individual is very small, and the other is quite large, especially when comparing the proportions of the fossils and the pattern of growth inside the bones.
Scientists estimate that the larger species weighed more than800 kg, and the second individual was most likely still developing when it died. This makes it one of the largest ornithomimosaurs ever discovered.
