English: Harenadraco is a small troodontid dinosaur from the Late Cretaceous of what is now Mongolia. It was small and lightly built, typical for troodontids, but Harenadraco had uniquely slender legs. This adaptation, which allowed for skilled running abilities, implies that it could have hunted highly agile prey. Harenadraco was about 1 m in length, and most likely covered in feathers, which further aided in its agility while running and hunting.
