All troodontids have many unique features of the skull, such as closely spaced teeth in the lower jaw, and large numbers of teeth. Troodontids have sickle-claws and raptorial hands, and some of the highest non-avian encephalization quotients, meaning they were behaviourally advanced and had keen senses.[1]

| - Philovenator is a troodontid, a group of small, bird-like, gracile maniraptorans. All troodontids have many unique features of the skull, such as closely spaced teeth in the lower jaw, and large numbers of teeth. Troodontids have sickle-claws and raptorial hands, and some of the highest non-avian encephalization quotients, meaning they were behaviourally advanced and had keen senses.[1] Several distinguishing traits were established in the initial description. The thighbone possesses a distinctive process at the inner side of the lower end. The shinbone has on the upper front side a plate-like cnemial crest, protruding far to the front. The condyles of the astragalus and calcaneum are wide, measured from the front to the rear, and are separated by a deep and narrow groove. The metatarsus has fused with the lower ankle bones into a very elongated and narrow tarsometatarsus, being 25% longer than the thighbone and twenty-five times longer than wide. Of this tarsometatarsus the thickness of the middle section of the shaft, measured from the front to the rear in a vertical position, is larger than its transverse width. The fourth metatarsal at its underside, if the bone is held in a horizontal position, has a flange along most of the shaft length, being almost as wide as the remainder of the shaft.
