Pengornis: Research Database
Enantiornithes (Aves) · Early Cretaceous (~125-120 MYA) · Asia — China (Liaoning, Jiufotang Formation)
Research Note: Pengornis was an enantiornithine bird from the Early Cretaceous of Liaoning, China — one of the largest known enantiornithines and an important taxon for understanding early avian evolution in the Jehol Biota.

Active Debate: Enantiornithine Diversity and the Early Evolution of Birds
Whether enantiornithines like Pengornis were diverse and widespread in the Early Cretaceous is debated. The evolution of enantiornithines — and their relationships to modern birds — is key to understanding avian origins.
What We Still Do Not Know About Pengornis
- Complete skeletal morphology: Known from relatively complete specimens.
- Flight capability: Debate ongoing.
- Diet: Likely carnivorous/insectivorous.
- Social behavior: No direct evidence.
In Depth
Pengornis is a genus of enantiornithine bird that lived in China during the early Cretaceous.
