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. Ornitholestes and the Alvarezsauroidea are also often included.

Maniraptors ("hand snatchers") is a clade of coelurosaurian dinosaurs starting in the Jurassic period. Many paleontologists believe birds evolved from them some 150 or so million years ago. Hence, according to phylogenetic taxonomy, birds are by definition maniraptors, and the other maniraptors are their closest relatives.

Jul 17, 2024 · Maniraptorans are the most diverse clade of dinosaurs. None retain a basal theropod form: indeed, very few retain the ancestral carnivorous condition. Major groups include the Therizinosauria, Alvarezsauria, Oviraptorosauria, and Eumaniraptora (which get …

Coelurosauria is a subgroup of theropod dinosaurs that includes compsognathids, tyrannosauroids, ornithomimosaurs, maniraptorans, and possibly megaraptorans. Maniraptora includes birds, the only known dinosaur group alive today. [5] Most feathered dinosaurs discovered so far have been coelurosaurs.

The maniraptorans comprise birds, dromaeosaurs, and troodontids. Dromaeosaurs were medium-size predators with long, grasping arms and hands, moderately long legs, and a specialized stiffened tail that could be used for active balance control. Their feet bore large talons on one toe that were evidently used for…

Maniraptora is a clade used in phylogenetic taxonomy which covers the birds and the dinosaurs that were most closely related to them. It is a sister group to Ornithomimiformes and contains the major subgroups Deinonychosauria, Oviraptorosauria and Therizinosauria, and Aves.

At 7 feet long, Deinonychus belonged to a group of dinosaurs called maniraptors, or "hand-robbers." Its hands and feet were equipped with sharp claws for catching and grasping prey. The dinosaur's hollow bones and long legs indicate swift and agile movement.

Jun 13, 2011 · Several maniraptor taxa have been found in such deposits, many of them preserving feathers. In some cases it is also possible to infer the presence of feathers through skeletal features. To date, at least fifteen non-avialian maniraptors have been preserved with direct evidence of feathers.

Jul 21, 2023 · Within the realm of prehistoric wonders, the maniraptorans stand out as one of the most intriguing groups. One of the most striking aspects of maniraptorans is their incredible range in size...

Maniraptorans are characterized by long arms and three-fingered hands (though reduced or fused in some lineages), as well as a "half-moon shaped" (semi-lunate) bone in the wrist (carpus). Maniraptorans are the only dinosaurs known to have breast bones (ossified sternal plates).
