Qianshanornis rapax is an extinctpredatorybird from the Middle Paleocene of China. Q. rapax is the first (chronologically and otherwise) cariamiform bird to have been found in Asia. It is very similar to the EoceneStrigogyps, but it differs in being smaller, and in having a hypertrophied, hyperextensible second toe, forming a claw analogous to that of dromeosaurdinosaurs. This toe is thought to allowed the bird to better pin down captured prey. Although very little wing-material is known, the condylar processes suggest it was capable of flight, and probably was a flier superior to either Strigogyps or modern seriemas.[1]
