Struthio anderssoni, also known as the East Asian ostrich, is an extinct species of ostrich that lived in the Pleistocene and Holocene in China and Mongolia. The youngest dates obtained by mass spectrometry analysis of eggshell fragments reveal that the species survived until at least 8.9 ka BP.{{cite journal |last1=Janz |first1=Lisa |last2=Elston |first2=Robert G. |last3=Burr|first3=George S.|date=18 May 2009 |title=Dating North Asian surface assemblages with ostrich eggshell: implications for palaeoecology and extirpation |journal=Journal of Archaeological Science |volume=36 |issue= 9|pages=1982–1989 |doi=10.1016/j.jas.2009.05.012 |bibcode=2009JArSc..36.1982J |access-date=}}
