With the largest brain of any dinosaur in proportion to its size, this was perhaps one of the smartest dinosaurs. And with excellent vision and long, serrated teeth, this scaly-skinned, fast, light theropod must have been a deadly night hunter. Standing as tall as an adult human and reaching weights of roughly 110 pounds, it had very dexterous hands and probably fed on relatively small prey, including mammals, lizards, insects and perhaps newborn dinosaurs.
