Tianyuraptor had very short forelimbs, unlike many other dromaeosaurids that had long arms.1
Its tail was extremely long, measuring about 960 millimetres (38 inches), which is nearly 4.8 times the length of its thigh bone.1
Tianyuraptor had a small and slender wishbone (furcula), which is different from the larger wishbones of its flying relatives.1
Its hindlimbs were about three times as long as its backbone, making it a fast runner.1
The only known fossil of Tianyuraptor is a nearly complete skeleton, missing only the tip of the tail.1
Tianyuraptor lived during the Early Cretaceous period, about 122 million years ago, in the Yixian Formation of China.1
