Incisivosaurus was a small feathered dinosaur from early Cretaceous China. Nigel encountered a male Incisivosaurus around the beginning of episode three and then again around the end when two males destroy the Microraptor trap (probably because they seemed to be territorial or competitive during the mating season).
Incisivosaurus was named for its rodent-like front teeth. These dinosaurs did have feathers and probably used them for display, like a peacock's tail. Their protruding front teeth were about 5 inches (12.5 cm) long.
Like modern song-birds, Incisivosaurus used their feathery-wing like arms for mating displays, especially competing with other Incisivosaurus for food and space.
- Incisivosaurus should not have pronated hands, which dinosaurs are often portrayed with in media. Their wrist bones were physically incapable of pronating.
- Their wings should be larger and probably covered their third fingers.
- Their tail fans could have been larger in real life, though it is a speculation.
