Description
The holotype specimen is remarkably complete for a Late Cretaceous enantiornithine, possessing an extremely well-preserved skull and wing bones. Unlike most enantiornithines, the skull of Yuornis was convergently similar to that of modern birds, being completely toothless.[1]
Classification
Xu et al. found Yuornis to be sister to Gobipteryx, which would by definition place it in the family Gobipterygidae, but they refrained from assigning to the family.[1]
