Ornithomimosaur

Ornithomimosaurs, or ostrich dinosaurs, are coelurosaur theropods with a very great resemblance to Ostriches, and Moas. They are coelurosaurs like birds, Tyrannosaurus, and Velociraptor. They have been found in North America, Europe, and Africa. Tracks from South America  may be from Ornithomimosaurs. And possible fossils are known in Australia. Members of the family include Gallimimus, and Ornithomimus.

In New Zealand
Ornithomimosaurs may have roamed New Zealand based on phalanx bones in the Chatham Islands. The theropod was possibly around meters 4 long which is as long as a Struthiomimus. It lived alongside a large basal allosauroid with a skinnier phalanx than Carnotaurus from Argentina, Bolivia, and Antarctica.
