'Troodon' (also known as Stenonychosaurus) is a genus of small theropod dinosaur. Its name ("TROE-odon") is Greek for "wounding tooth", referring to the dinosaur's teeth, which are different from those of most other theropods. The teeth bear prominent, apically oriented serrations.
Troodon is a small dinosaur, around 2 meters (6.5 ft) in length, 1 meter (3 ft) tall, and weighed 60 kilograms (130 lb). It has very long, slender limbs. It has long 'arms' that fold against the wall of the thorax like a bird's. It has large, retractable sickle-shaped claws on its second toes, which are raised off the ground when running. Because of these features scientists regard Troodon as a member of the Maniraptora. Its eyes are large and slightly forward facing, giving Troodon some depth perception. Troodon has one of the largest known brains of any dinosaur, relative to its body mass. Hence it is believed to be one of the most intelligent dinosaurs (Zippo for instance is a perfect example).
Because of the size of their brain and the example of Malik and Zippo, the Troodons are most likely some of the more scholarly dinosaurs of Dinotopia.
