Originally known from a pair of massive, nearly 8 ft long arms, found by a joint Polish-Mongolian team in the 60s, back when both nations were cooler, in the Gobi desert, further remains were found in the early 2010s.

"An adult stood 5 meters (16 feet) tall, and measured more than 10 meters (33 feet) in length. The skull was very long, narrow, and tall, with a wide bill at the end. Viewed in profile, it might resemble a toucan with an ice scraper on the tip of the bill. The jaws had no teeth, but instead bore a beak. The enormous head and long neck led to a sail-back pot-bellied torso atop stout legs that did little running. The sail-back was formed by long spines on its vertebrae and form a point over the middle of the back making it look like a hump-back. Round stones discovered in the rib cage have been interpreted as gastroliths – stones that are swallowed and held in the gizzard to to grind tough food. Other ornithomimosaurs and their closest relatives are known to be feathered, so it's likely that Deinocheirus was feathered too." https://eartharchives.org/articles/deinocheirus-the-giant-hunchbacked-dinosaur-with-terrifying-hands/index.html

It will also be featured in the game Prehistoric Kingdom, a game I hope actually gets made and that I can actually play if and when that happens, because I wanna make a dino zoo this would make me very very happy and I want to see this weirdo in it
