Bannykus: Research Database
Alvarezsauria (Theropoda) · Late Cretaceous (~95 MYA) · Asia — China (Inner Mongolia, Xinjiang)
Research Note: Bannykus was an alvarezsaur from the Late Cretaceous of China — an important taxon for understanding the evolution of alvarezsaur theropods and their unusual morphological adaptations.

Active Debate: Alvarezsaur Evolution
Whether Bannykus represents a transitional form between early and derived alvarezsaurids is debated. The evolution of alvarezsaur theropods — and their unusual morphological adaptations — is key to understanding theropod diversity in the Cretaceous.
What We Still Do Not Know About Bannykus
- Complete skeletal morphology: Partial specimen known.
- Diet: Insectivore.
- Social behavior: No direct evidence.
- Relationships: Partially understood.
In Depth
Bannykus is a genus of alvarezsaurid dinosaur that lived in Asia during the early Cretaceous. The overall lack of fossil remains at the time of its description makes it hard to ascertain details about Bannykus, though the size of the leg bones alone suggest that Bannykus was among the larger known alvarezsaurs.
