Bird tracks from Liaoning Province, China: New insights into avian evolution during the Jurassic-Cretaceous transition

The most distinctive tracks are here named Pullornipes aureus ichnosp. nov. and are tentatively assigned to the ichnofamily Koreanornipodidae. Other tracks from the same site appear to represent different ichnotaxa and therefore indicate the potential to find diverse avian ichnofaunas at this time. This record supports the evidence that East Asian avian ichnofaunas are the most diverse known during the Early Cretaceous.
