A sister group to Arctometatarsalia containing the subgroups Deinonychosauria, Oviraptorosauria, Therizinosauria, and Aves.

Maniraptors are characterized by elongated arms and hands, as well as a semi-lunate carpal in the wrist. Other basal maniraptor traits include the presence of a furcula, a distally shortened and stiffened tail, feathers and an elongated, backwards-pointing pubis. The "killer claw" which characterizes dromaeosaurs may also be a basal trait.

Modern pennaceous feathers, remiges and powered flight is present in species from several maniraptorian subgroups including aves and dromaeosauridae.
