Deinocheirus was the largest ornithomimosaurian (ostrich dinosaur) and a weird looking dinosaur. Unlike its cousin fast and lightweight, Deinocheirus is heavy and massive with large spines and a duck-like skull designed for an omnivorous diet, which seems to be confirmed by the presence of fish remains and marine plant and a thousand gastroliths. In the documentary in nat geo "Weird dinosaurs", in 2007, it is run as a giant ornithomimidae that clings to trees thanks to its claws, the same way that the Megatherium. It is noted that ,in 2006, the only fossil evidence is its arms and hands. It was in 2014 that discovered the rest of his body.
