Longusunguis is an extinct genus of bohaiornithid enantiornithine dinosaur known from the Early Cretaceous of Liaoning Province, northeastern China. It contains a single species, Longusunguis kurochkini.
Longusunguis was first described and named by Min Wang, Zhong-He Zhou, Jingmai K. O'Connor and Nikita V. Zelenkov in 2014 and the type species is Longusunguis kurochkini. The generic name is derived from the Latin words longus, meaning "long", and unguis, meaning "claw", in reference to the distinctly elongated pedal unguals that this taxon shares with other bohaiornithids. The specific name, kurochkini, honors the late Prof. Evgeny Kurochkin, a prominent paleontologist, for his contributions to the study of fossil birds.
Longusunguis is known solely from the holotype IVPP V 17964, a complete and articulated skeleton and skull. It is preserved in a single slab and currently housed at the Institute of Vertebrate Paleontology and Paleoanthropology, Beijing. IVPP V 17964 was collected at deposits near the Lamadong Town, Jianchang County of the Liaoning Province, from the Jiufotang Formation, dating to the Aptian stage of the Early Cretaceous, approximately 120.3 million years ago.
