(troh-uh-don)
Meat-eater
11.5 feet long
Late Cretaceous, 65 million years ago
Western Canada
Only the size of a second-grader, this meat-eater was the smartest of all dinosaurs. It could hunt at twilight because of its excellent vision. It had a large claw on each foot, like "raptor" dinosaurs but Troodon's claws were small and delicate.
