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 .

Alvarezsauridae is a family of small, long-legged dinosaurs.Although originally thought to represent the earliest known flightless birds, they are now thought to be an early diverging branch of maniraptoran theropods.
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.
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 [2] and considered to be flightless birds, [4] 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.

Therizinosaurids were quite advanced and robustly-built animals that reached multi-ton dimensions which make them among the largest maniraptorans. The smallest known therizinosaurids are Erliansaurus , Erlikosaurus and Neimongosaurus which were around 3–4 m (9.8–13.1 ft) long, furthermore the holotype skull of Erlikosaurus is about 25 cm ...
Scansoriopterygidae (meaning "climbing wings") is an extinct family of climbing and gliding maniraptoran dinosaurs.Scansoriopterygids are known from five well-preserved fossils, representing four species, unearthed in the Tiaojishan Formation fossil beds (dating to the mid-late Jurassic Period) of Liaoning and Hebei, China.
Recent studies have shown that the animal was actually on top of its own nest. [ 14 ] A 2022 study of the bite forces of oviraptorosaurs such as Incisivosaurus , Khaan , Citipati , and Conchoraptor suggests that most if not all oviraptorosaurs had a very strong bite force.
