Longipteryx: Research Database
Enantiornithes (Aves) · Early Cretaceous (~120 MYA) · Asia — China (Yixian Formation)
Research Note: Longipteryx was an enantiornithine bird from the Early Cretaceous of Liaoning, China — a toothed early bird and an important taxon for understanding avian evolution in the Early Cretaceous.

Active Debate: Early Avian Evolution in the Cretaceous
Whether enantiornithines like Longipteryx were ancestral to modern birds is debated. The evolution of birds in the Cretaceous — and their survival through the K-Pg extinction — is key to understanding avian history.
What We Still Do Not Know About Longipteryx
- Complete skeletal morphology: Known from well-preserved specimens.
- Flight capability: Debated.
- Diet: Likely fish.
- Social behavior: No direct evidence.
In Depth
Longipteryx is a genus of enantiornithine bird that lived in China during the later stages of the early Cretaceous, and when compared to other enantiornithine birds living at the time, Longipteryx had exceptionally good adaptations for flying and perching.
