Known locations: China, Sichuan Province - Dashanpu Formation - Lower Shaximiao Formation.
Time period: Bathonian/Callovian of the Jurassic.

A little known theropod dinosaur from China, a 2010 study by Benson et al found Chuandongocoelurus to probably be related to the more complete Monolophosaurus. The partial remains of Chuandongocoelurus are thought to be from a juvenile/subadult individual, and coupled with the overall incomplete nature of them, it is impossible to establish an accurate size estimate for this dinosaur.
