Overview
Name meaning: Horrible Hands
Time Period: Late Campanian-Early Maastrichtian ( Late Cretaceous)
Locations: Mongolia Nemegt Formation
Taxonomy: Theropoda - Ornithomimosauria - Deinocheiridae
Subspecies: D.mirificus
Characteristics
Deinocheirus was magnificent; the subspecies D.mirificus means unusual and wonderous. It was massive being 11 meters in length, a giant having a size similar to a Tyrannosaurus. It had a giant beak like a duck and its fossils contained fish scales meaning it was a piscivore while also being a herbivore eating the river plants of its environment and fishing. Its back vertebrae formed a hump to make it look bigger and possibly store fat and the tail vertebrae formed a pygostyle which is an attachment point for feathers meaning Deinocheirus had a tail fan. As for those feathers, Deinocheirus was most likely a heavily feathered dinosaur with a thick shaggy coat to protect its skin. Its large horrible hands served various purposes with hunting and defense and foraging difficult-to-reach plants, pretty typical uses, nothing horrible about them I’d say. Deinocherius lived in the very now fossil-rich Nemegt formation, species known to have coexisted with Deinocheirus are hadrosaurus like Barsboldia and Saurolophus, Titanosaurs Nemegtosaurus and Opisthocoelicaudia dome heads such as Homalocephale and Prenocephale. As well as other species like Gallimimus Protoceratops Velociraptor Therizinosaurus Tarcia and Tarbosaurus.
History
Deinocheirus was originally discovered in 1965 in the Gobi desert of Mongolia. The skeleton was extremely fragmentary except for its forelimbs, which gave the creature its name. It was believed for a while that it was a carnivorous theropod with disproportionately large arms. Further analysis found Deinocheirus was closest to an herbivorous ornithomimosaur or ostrich mimic having very similar hands but that's mostly where the similarities end. Deinocherius was elusive; nobody knew what this mysterious therapod may have looked like. It wasn't until 2011 that a paleontologist met up with a French fossil dealer who had acquired several bones of a Deinocheirus, including a skull, spine, feet, and most importantly a hand. It was this that revealed most of the mystery of what Deinocheirus was
Media Deptictions
Prehistoric Planet: season _ only has one scene featuring the Deinocheirus. In it, the Single Deinocheirus is being onslaughted by blood-sucking flies before finding a suitable tree to scratch its back upon. Then they had to show off the importance of taking a crap (weird)
