We intend to describe the skeletal anatomy and phylogeny of one of the earliest maniraptoran dinosaurs of North America. Maniraptoran theropods (including the famous Velociraptor) were the group of dinosaurs that includes the ancestors of birds. The new specimen lived in Wyoming during the Late Jurassic Period (~150 mya). Only three feet long, this new species is one of the smallest dinosaurs from the Morrison; it's considered a missing link between small, meat–eating dinosaurs and modern birds.
