Maniraptora is a clade of coelurosaurian dinosaurs which includes the birds and the non-avian dinosaurs that were more closely related to them than to Ornithomimus velox. It contains the major subgroups Avialae , Dromaeosauridae , Troodontidae , Oviraptorosauria , and Therizinosauria .

Coelurosauria is a subgroup of theropod dinosaurs that includes compsognathids, tyrannosaurs, ornithomimosaurs, and maniraptorans; Maniraptora includes birds, the only known dinosaur group alive today. [5] Most feathered dinosaurs discovered so far have been coelurosaurs.
Size comparison of several parvicursorines: Parvicursor remotus (green), Ceratonykus oculatus (red), Shuvuuia deserti (blue), and Mononykus olecranus (violet). Alvarezsaurids ranged from 50 centimetres (20 in) to 2 metres (6.6 ft) in length, although some possible members may have been larger, including the European Heptasteornis that may have reached 2.5 metres (8.2 ft) long.
The phylogenetic placement of Alvarezsauroidea is still unclear. At first, they were interpreted as a sister group of Avialae (birds) or nested within the group Avialae [1] and considered to be flightless birds, [3] because they share many morphological characteristics with them, such as a loosely sutured skull, a keeled sternum, fused wrist elements, and a posteriorly directed pubis.

Oviraptoridae is a group of bird-like, herbivorous and omnivorous maniraptoran dinosaurs.Oviraptorids are characterized by their toothless, parrot-like beaks and, in some cases, elaborate crests.

Coelurus (/ s ɪ ˈ lj ʊər ə s / si-LURE-əs) is a genus of coelurosaurian dinosaur from the Late Jurassic period (mid-late Kimmeridgian faunal stage, 155–152 million years ago).). The name means "hollow tail", referring to its hollow tail vertebrae (Greek κοῖλος, koilos = hollow + οὐρά, oura = t
