Hongshanornis: Research Database
Ornithothoraces (Aves) · Early Cretaceous (~125 MYA) · Asia — China (Jehol Biota, Yixian Formation)
Research Note: Hongshanornis was a small ornithothoracine bird from the Early Cretaceous Yixian Formation of Liaoning, China. Known from exquisitely preserved specimens showing feather impressions and soft tissue, it provides critical data on the diversity and ecology of early birds in the Jehol Biota. Its name references the Hongshan culture of northeastern China.

Active Debate: Ornithothoracine Phylogeny and Early Bird Diversity in the Jehol Biota
The precise phylogenetic placement of Hongshanornis within Ornithothoraces and its ecological diversity relative to other Jehol birds remain active areas of research.
What We Still Do Not Know About Hongshanornis

- Flight capability: Inferred from wing morphology.
- Social behavior: No direct evidence.
In Depth
Hongshanornis was an early bird that lived in China during the early Cretaceous period. Most interpretations of Hongshanornis depict it as being a wading bird but one that was still capable of flight. The wings were fairly broad and tapered out to triangular points at the end. If Hongshanornis was a wader then it was most likely also an insectivore plucking up small invertebrates from the mud and aquatic plants.
In the type specimen of Hongshanornis it was considered that there might have been a crest present on the head. This was because an impression was left around the skull on the slab that the specimen was preserved on, though it was also noted that this impression might have been artificially created during the fossilisation process. A second specimen of Hongshanornis was later found without any hint of feather impressions, meaning that this specimen at least had no crest at the time of death, and possibly no members of the genus had a crest.
