Troodontidae is a family of bird-like theropod dinosaurs. During most of the 20th Century, troodontid fossils were few and scrappy and they have therefore been allied, at various times, with nearly every major coelurosaurian lineage. More recent fossil discoveries of complete and articulated specimens, (including specimens which preserve feathers, eggs and embryos, and complete juveniles) have helped to increase understanding about this group. Anatomical studies, particularly studies of the most primitive troodontids, like Sinovenator, demonstrate striking anatomical similarities with Archaeopteryx and primitive dromaeosaurids, and demonstrate that they are relatives comprising a clade called Paraves.

- Troodontids are a subgroup of bird-like dinosaurs that are closely related to their more robust and better-known dromaeosaur brethren. The troodontid family were thought to be the smartest of dinosaurs, because of studies of the brain cavities of the family group. Troodontids were relatively small, measuring only around 3-6 feet in length, and while most had sickle-claws on their feet, theirs appeared far less lethal than dromaeosaurs' claws. The diets of troodontids strangely varies within the family, with some clear carnivores, some likely omnivores, and some even potential herbivores.

abstract
| - Troodontids are a subgroup of bird-like dinosaurs that are closely related to their more robust and better-known dromaeosaur brethren. The troodontid family were thought to be the smartest of dinosaurs, because of studies of the brain cavities of the family group. Troodontids were relatively small, measuring only around 3-6 feet in length, and while most had sickle-claws on their feet, theirs appeared far less lethal than dromaeosaurs' claws. The diets of troodontids strangely varies within the family, with some clear carnivores, some likely omnivores, and some even potential herbivores. As small theropods, Troodontids are Wind Dinosaurs, though they have appeared in Normal Moves.
