Ornitholestes

Ornitholestes is a genus of theropod dinosaur which lived during the late Jurassic period in what is now North America. (150-139 MYA).

Facts
Ornitholestes was a relatively small dinosaur, measuring 2.5 meters in length and weighing around 15 kg. This dinosaur lived in the same place and the same time as many of the giant Jurassic dinosaurs like Apatosaurus, Stegosaurus and Allosaurus. However, Ornitholestes most likely stayed away from these animals and focused on hunting small animals and baby dinosaurs, as seen in Time of the Titans.

When Ornitholestes was discovered, scientists believed that it had a nasal crest but that theory is now disproven. However, now scientists believe that Ornitholestes had at least some sort of feathers, maybe even true feathers if it was indeed a real maniraptoran.
