Troodon is a genus of dinosaur belonging to the family Troodontidae. It lived approximately 76 to 66 million years ago during the Late Cretaceous period in what is now North America and Asia. The first fossils of Troodon were discovered in the late 1800s, and subsequent finds have provided paleontologists with insights into this fascinating dinosaur.

Troodon was a medium-sized dinosaur, measuring about 2 to 3 meters in length and weighing around 50 to 100 kilograms. It had a slender body, long hind limbs, and grasping hands with three-fingered claws. One of its most distinctive features was its large brain relative to its body size, suggesting high intelligence among dinosaurs. Troodon had forward-facing eyes, indicating binocular vision and depth perception.

Troodon is believed to have been a highly active and agile predator, employing its speed, agility, and intelligence in hunting and foraging. Its binocular vision and large brain likely facilitated complex behaviors and problem-solving abilities. Troodon may have been nocturnal or crepuscular, taking advantage of low-light conditions to maximize hunting success.
