 The front limbs of "Austroraptor" were short for a dromaeosaur, with its humerus less than half the length of its femur.Among the Dromaeodauridae, only this genus, "Tianyuraptor", "Zhenyuanlong" and "Mahakala" have similarly reduced forelimbs.The relative length of its arms has caused "Austroraptor" to be compared to another, more famous short-armed dinosaur, "Tyrannosaurus," though there is no close relationship between the two taxa.
