Phaedrolosaurus is a problematic genus of dinosaur because at the time of writing the only fossil specimen for this genus is a single tooth. Partial post cranial remains that were once attributed to the genus upon the basis that they were found near the tooth have since been removed and used to establish a whole new genus called Xinjiangovenator. The tooth of Phaedrolosaurus has no real distinctive features other than resembling the teeth of other dromaeosaurid dinosaurs, and for this reason Phaedrolosaurus is usually treated as a Nomen dubium.
