Troodon was a small, bird-like dinosaur that lived during the late Cretaceous period, around 75 million years ago. It was about the size of a modern-day turkey, measuring around 2 to 3 feet long. Troodon is known for its large eyes, which suggest it was likely nocturnal, and its sharp teeth, indicating it was an omnivore that ate both plants and small animals. This dinosaur is often recognized for its unique features, including a large brain relative to its body size, suggesting it may have been one of the most intelligent dinosaurs. Fossils of Troodon have been found in North America, providing valuable insights into the diversity of dinosaur species during its time.
