Description
editDzharaonyx is known from a series of disassociated but well-preserved postcranial material. The form of the humerus is intermediate between that of Patagonykus and Mononykus.[1]
Classification
editPhylogenetic analysis places Dzharaonyx in a polytomy including other Asian members of Parvicursorinae. This makes it the oldest parvicursorine known to date.[1]

Paleoenvironment
editDzharaonyx lived in the Bissekty Formation, which has been intensively studied in recent years. It represents a brackish environment.[3] It coexisted with larger theropods including the dromaeosaurid Itemirus, the tyrannosauroid Timurlengia, and the troodontid Urbacodon. The hadrosaur Levnesovia, ankylosaurs, and the sauropod Dzharatitanis represented the herbivores in this ecosystem.
