Maniraptora is the only dinosaur group known to include flying members, though how far back in this lineage flight extends is controversial. Powered and/or gliding flight is believed to have been present in some types of non-avialan paravians, including dromaeosaurids, such as Rahonavis and Microraptor . [ 7 ]
Articles related to the Maniraptora, 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 .
The private sale of fossils has attracted criticism from paleontologists, as it presents an obstacle to fossils being publicly accessible to research. [2] Most countries where relatively complete dinosaur specimens are commonly found have laws against the export of fossils. The United States allows the sale of specimens collected on private ...
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.
The type specimen of Scansoriopteryx heilmanni (specimen number CAGS02-IG-gausa-1/DM 607) represents the fossilized remains of a hatchling maniraptoran dinosaur, similar in some ways to Archaeopteryx. A second specimen, the holotype of Epidendrosaurus ninchengensis (IVPP V12653), also shows features indicating it was a juvenile.
[26] [27] [28] The placement of Therizinosauria within Maniraptora continued to be unclear; in 2007, paleontologist Alan H. Turner and colleagues found them to group with oviraptorosaurs, while Zanno and colleagues found them to be the most basal clade within Maniraptora in 2009, bracketed by Ornithomimosauria and Alvarezsauridae.
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 .
