       Although not very well known,‭ ‬Tianyuraptor is important to many palaeontologists because it is often regarded as a transitional form that links northern and southern genera of dromaeosaurids.‭ ‬Tianyuraptor is noted for having a smaller than usual furcula and arms that are proportionately much smaller than those of other dromaeosaurid genera.‭ ‬Overall,‭ ‬Tianyuraptor is actually quite a bit larger than most other known microraptorian dromaeosaurs,‭ ‬though it still has the long hind leg proportions,‭ ‬meaning that it was likely a very fast runner for its size.‭ ‬The‭ ‬proportionately much smaller arms however mean that there was practically no chance that it could glide for short distances,‭ ‬as has been proposed for some other smaller microraptorian genera like Microraptor.
