Camptodontornis is an extinct genus of enantiornithine bird which existed in what is now Chaoyang in Liaoning Province, China during the early Cretaceous period (Aptian age). It is known from a well-preserved skeleton including a skull found in the Jiufotang Formation of Liaoning Province. Its original generic name was "Camptodontus" (meaning "bent tooth"); it was named by Li Li, En-pu Gong, Li-dong Zhang, Ya-jun Yang and Lian-hai Hou in 2010. However, the name had previously been used for a genus of beetle (Dejean, 1826).[1] The type species is "Camptodontus" yangi.[2] Demirjian (2019) coined a replacement generic name Camptodontornis.[3] The status of C. yangi as a distinct species is disputed, with Wang et al. (2015) considering it to be a probable synonym of Longipteryx chaoyangensis.[4]
