       Daliansaurus is a genus of small troodontid dinosaur that lived in China during the early Cretaceous.‭ ‬Many trrodontid dinosaurs are known to‭ ‬have been living in the same approximate time and location as Daliansaurus,‭ ‬but the describing paleontologists identified several features that differentiate this genus from others.‭ ‬Some of the clearer differences are that the humerus‭ (‬upper arm bone‭) ‬is longer than most other troodontid genera in the regions,‭ ‬and the teeth have a‭ ‘‬D‭’ ‬shape to them instead of being recurved‭ (‬curving so the tips point back slightly towards‭ ‬the back of the mouth‭)‬.‭ ‬Most telling of all perhaps is the presence of an enlarged claw on the fourth toe of the foot,‭ ‬in addition to the large sickle shaped claw on the second toe.
       Daliansaurus is among several troodontid dinosaurs known from the Yixian Fomration.‭ ‬These include Sinovenator,‭ ‬Mei and Sinusonasus,‭ ‬which may have been closely related to Daliansaurus,‭ ‬as well as Jianianhualong and Liaoningvenator.
