Troodontidae is a family of small, bird-like dinosaurs that lived during the Late Cretaceous period. They are known for their unique features, including large eyes, a keen sense of vision, and a highly developed brain relative to their body size. Troodontids are often considered to be among the most intelligent dinosaurs. These dinosaurs had long, slender limbs and were likely agile and fast runners. Their teeth were adapted for an omnivorous diet, suggesting they could eat both plants and small animals. Fossils of Troodontidae have been found in various locations, providing insights into their diverse habitats and behaviors.
