Deinocheirus is an ornithomimosaurian theropod dinosaur from the Late Cretaceous of Mongolia.
Little skeletal material of Deinocheirus has been formally described. Its most completely known elements are its forelimbs, which each measure two and a half meters in length. Its hands bore claws that were nearly 20 centimeters long. Ribs and vertebrae are also known.
New specimens of Deinocheirus have recently been discovered. While they are yet to be formally described, the new fossil material confirms their ornithomimosaurian identity and indicates that the dinosaur had a sail or hump on its back much like Spinosaurus or Ouranosaurus. The skull was stolen by looters, but was later recovered and returned to Mongolia. Descriptions and photographs reveal that the skull looks superficially similar to that of a hadrosaur.
