Exempel på hur man kan använda MANIRAPTORAN i en mening

• The slightly older Koparion of Utah is only represented by a single tooth, and small maniraptoran teeth from the Middle Jurassic of England were identified as those of indeterminate troodontids in 2023.
• Across the monographs in the Dinosaur Museum Journal, Stephen Czerkas built a case for his controversial view that maniraptoran dinosaurs are secondarily flightless birds.
• The region that is preserved in the Barun Goyot Formation was home to the maniraptoran Hulsanpes perlei, the oviraptorids Conchoraptor gracilis and Ajancingenia yanshini, the alvarezsaurids Ceratonykus oculatus, Mononykus and Parvicursor remotus, the pachycephalosaur Tylocephale gilmorei, the ankylosaurs Saichania chulsanensis and Tarchia gigantea, and the ceratopsians Bagaceratops rozhdestvenskyi, Breviceratops kozlowskii, Lamaceratops tereschenkoi and Platyceratops tatarinovi.
• Pedopenna was originally classified as a paravian, the group of maniraptoran dinosaurs that includes both deinonychosaurs and avialans (the lineage including modern birds), but some scientists have classified it as a true avialan more closely related to modern birds than to deinonychosaurs.
• 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.
• Specifically, the semilunate carpal bone of the wrist is found only in maniraptoran theropods, which also include oviraptorosaurs, dromaeosaurs, troodontids, and birds.
• However, based on differences between the two femora that were likely unrelated to conspecific allometry or ontogeny, later researchers have suggested that the paratype femur may instead represent an indeterminate maniraptoran.
• it was described as the earliest known member of the pachycephalosaurid family, but research by Darren Naish shows it to have actually been a theropod, seemingly a maniraptoran.
• Dyke did not follow the synonymy and found Heptasteornis to be an alvarezsaurid, while classifying Bradycneme as an indeterminate maniraptoran.
• In 2004, Darren Naish and Gareth Dyke considered Elopteryx as a Eumaniraptora incertae sedis, possibly either a non-ornithuromorphan pygostylian bird or a troodontid, while Bradycneme would be a maniraptoran, and the dubious Heptasteornis (at least its holotype BMNH A4359) a member of the Alvarezsauridae.
• Though it has been since been typically identified as an indeterminate "coelurian" theropod, Thecocoelurus was reidentified by Darren Naish and colleagues in 2001 as a member of the Oviraptorosauria, a group of omnivorous maniraptoran theropods, which would make it the only oviraptorosaur fossil that has ever been found in Europe.
• Novas and colleagues suggested that the plates may be homologous to uncinate processes, strip-like bony projections found on the ribs of a variety of animals including the tuatara, crocodiles, birds, and some maniraptoran theropod dinosaurs.
• The authors who initially described the fossil, classified Eshanosaurus as a member of the Therizinosauroidea on the basis of six distinct characteristics of the jaw and teeth, making it the earliest known coelurosaur, a maniraptoran living long before Archaeopteryx, 60 million years before certain basal therizinosaurs such as Falcarius and Beipiaosaurus.
• As a troodontid maniraptoran, it would have been bird-like, lightly built, with raptorial (grasping) hands and an enlarged sickle-shaped claw on the hyper-extendible second toe.
• In 2005, along with paleontologist Darla Zelenitsky, she described the oogenus Reticuloolithus: fossilized eggshells found in Alberta and Montana, believed to have been laid by maniraptoran dinosaurs such as oviraptorosaurs or dromaeosaurids.
• Paleontologist Jack Horner describes evolutionary developmental biology (evo-devo) and outlines his theory for being able to resurrect a maniraptoran dinosaur from a chicken embryo, by activating and deactivating certain genes to restore dormant dinosaur characteristics such as a tail, claws, teeth, and a snout.
• The hadrosauroid Jinzhousaurus is known from Baicai Gou, the same locality as that of Jianianhualong, as is the maniraptoran Yixianosaurus as well as hundreds of specimens from the choristodere Hyphalosaurus.
• Dinosaurs contemporaneous with Xiyunykus in the Tugulu Group of Xinjiang include the stegosaur Wuerhosaurus, the coeval alvarezsaur Tugulusaurus, the carcharodontosaurid Kelmayisaurus, the dubious maniraptoran Phaedrolosaurus, the problematic coelurosaur Xinjiangovenator, and the ceratopsian Psittacosaurus xinjiangensis.
• Their analyses recovered Overoraptor in a variety of positions including as a basal maniraptoran, a basal pennaraptoran, and a basal paravian, but they found the tree with the highest support values in their analysis recovered Overoraptor as the sister taxon of Rahonavis in a clade that is the sister-taxon of avialae and to which unenlagiidae is basal.
