Incisivosaurus was a small feathered dinosaur. 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 other Incisivosaurus for food and space.
