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 .
Migmanychion is a maniraptoran theropod, but its precise placement within the clade is unclear. Wang et al. (2023) noted several similarities between Migmanychion and Fukuivenator, a premise supported by their phylogenetic analyses.
In the modern fauna, theropods are represented by over 11,000 species of birds, which are a group of maniraptoran theropods within the clade Avialae.. Theropoda (/ θ ɪəˈr ɒ p ə d ə /; [2] from ancient Greek θηρίο-ποδός [θηρίον, (therion) "wild beast"; πούς, ποδός (pous, podos) "foot"]), whose members are known as theropods, is an extant dinosaur clade that is ...
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 synonymy of Segnosauridae with Therizinosauridae was accepted by Perle himself and co-authors of a redescription of the holotype skull of Erlikosaurus in 1994, and they considered therizinosaurs maniraptoran theropods, the group that also includes modern birds (since they did find Maniraptora to be valid through their analysis).
This list of non-avian theropod type specimens is a list of fossils that are the official standard-bearers for inclusion in the Mesozoic species and genera of the dinosaur clade Theropoda, which includes the carnivorous dinosaurs like Tyrannosaurus and Velociraptor, their herbivorous relatives like the therizinosaurs, and birds.
Russell and Dong concluded that they were theropods with unusual features. [27] In 1994, Clark and colleagues redescribed the very complete skull of Erlikosaurus and even more theropod traits were found this time. They also validated the synonymy of the Segnosauridae with Therizinosauridae and considered therizinosauroids as maniraptoran ...
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.
