English: Hypnovenator is a small troodontid dinosaur that lived about 110 million years ago in the Early Cretaceous of what is now Japan. Troodontids were closely related to birds, and had many superficial similarities, including their lightly built frame, and feathered integument. Hypnovenator was about 1 m in length, and stood on two long legs, allowing for swift running capability. These highly adapted limbs also allowed for the larger sickle-like toe claw on each foot to be held above the ground, keeping them sharp, even as it navigated its terrain.
