Exempel på hur man kan använda ORNITHOMIMOSAURS i en mening

• The trait appears to be highly homoplastic, common in certain sorts of dinosaurs accustomed to running (among them the tyrannosauroids, ornithomimosaurs, and troodontids), to evenly transmit force to the metatarsals.
• The moderate jaw gape seen in oviraptorosaurs is indicative of herbivory in the majority of the group, but it is clear they were likely feeding on much tougher or more types of vegetation than other herbivorous theropods in their environment, such as ornithomimosaurs and therizinosaurs were able to.
• Coelurosauria is a subgroup of theropod dinosaurs that includes compsognathids, tyrannosaurs, ornithomimosaurs, and maniraptorans; Maniraptora includes birds, the only known dinosaur group alive today.
• Tetanurae (/ˌtɛtəˈnjuːriː/ or "stiff tails") is a clade that includes most theropod dinosaurs, including megalosauroids, allosauroids, and coelurosaurs (which includes tyrannosauroids, ornithomimosaurs, compsognathids and maniraptorans, the latter including living birds).
• Some paleontologists, like Paul Sereno, consider the enigmatic alvarezsaurids to be close relatives of the ornithomimosaurs and place them together in the superfamily Ornithomimoidea (see classification below).
• It was an ornithomimosaur with a mix of basal and derived features; unlike primitive ornithomimosaurs, both upper and lower jaws were toothless, a trait that is often reported in more derived ornithomimids.
• The moderate jaw gape seen in oviraptorosaurs is indicative of herbivory in the majority of the group, but it is clear they were likely feeding on much tougher or more various types of vegetation than other herbivorous theropods in their environment, such as ornithomimosaurs and therizinosaurs were able to.
• This genus is paleontologically significant for being the first ornithomimosaur specimen known from England and represents the earliest record of ornithomimosaurs.
• It may be distinguished from the latter by its "straight ischial shaft and acuminateposterior end of the ilium" and from all other ornithomimosaurs excepting Harpymimus by the relative length of metacarpal I (only half that of metacarpal II) and in that its reduced dentition is restricted to the symphyseal portion of the dentary.
• The moderate jaw gape seen in oviraptorosaurs is indicative of herbivory, but it is clear they were feeding on much tougher vegetation than other herbivorous theropods in their environment, such as ornithomimosaurs and therizinosaurs.
• All the bones referable to ornithomimosaurs found at Phu Wiang 5 were disarticulated, and it is therefore impossible to know exactly how many individual animals were fossilized at the site.
• The first is the clade Arctometatarsalia, made up of tyrannosauroids, ornithomimosaurs, and troodontids, because all of these coelurosaurs had pinched middle metatarsal bones in their feet.
• There are also basal hadrosauroids, titanosauriform sauropods, and large herbivorous ornithomimosaurs and therizinosaurs.
• s 2008 paper described the KTR, it had been widely accepted in paleontology that new families of dinosaurs evolved during the Middle to Late Cretaceous, including the euhadrosaurs, neoceratopsians, ankylosaurids, pachycephalosaurs, carcharodontosaurines, troodontids, dromaeosaurs and ornithomimosaurs.
• However, Kol shows an extreme arctometatarsalian condition of the foot bones, in which the middle metatarsal is severely pinched between the outer bones (usually considered an adaptation for fast running, also seen in ornithomimosaurs and tyrannosaurs).
• They found that the support for the placement of Haplocheirus within alvarezsaurs and within compsognathids was roughly equivalent to the support values of the trees which placed it in ornithomimosaurs.
• A coelurosaur theropod, more closely related to ornithomimosaurs and maniraptorans than to tyrannosauroids.
• Paleontologists found that within the theropod family tree, ornithomimosaurs were primitive coelurosaurs closely related to, but outside of, the maniraptorans.
• Additionally, he argued that the characters cited are not unique to compsognathids, with fan-shaped neural spines being also seen in ornithomimosaurs and the troodontid Sinovenator, and the robust I-1 phalanx also being seen in alvarezsaurids.
• Some of these also exhibit evolutionary convergence upon archosaurs living after the Triassic–Jurassic extinction event - the phytosaurs resemble the thalattosuchians, gavialoids, and spinosaurids, the aetosaurs resemble the ankylosaurs, and the shuvosaurids resemble the ornithomimosaurs.
