Jiuquanornis anndaa e fosil gooto tan mo siforaa e hitaande 2013. Fosil oo ina waɗi feccere sternum, furcula, e forelimb.1

Sternum mum ina jogii projekti juutɗi, ɓeydiɗi, wiyeteeɗi trabeculae, ɗe kadi nji’aa e colli leydi hannde hono chicken e tinamous.1

Jiuquanornis ina jogii furcula (wishbone) U-shaped e angal toowngal ko ina tolnoo e 36 degre, e o alaa hypocleidium, projekti tokooso tawaa e colli goɗɗi.1
