Changzhousaurus (lit. 'Changzhou lizard') is an extinct genus of paravian theropod dinosaur known from the Early Cretaceous (Aptian age) Jiufotang Formation of China. The genus contains a single species, Changzhousaurus sinensis, known from a nearly complete, articulated skeleton with extensive associated feather traces, preserved as a part and counterpart.
Changzhousaurus is a very small dinosaur, with a body length of 34 centimetres (13 in). It has large wings on its forelimbs, paired with shorter hindlimb wings. It also has a fan of long, plume-like feathers at the end of its tail. The exact relationships of Changzhousaurus with other pennaraptoran theropods are unclear, given the conflicting anatomical characters of different groups, including troodontids, dromaeosaurids, anchiornithids, and avialans.
