In reality, however, Velociraptor was roughly the size of a turkey, considerably smaller than the approximately 2 m (6.6 ft) tall and 90 kg (200 lb) reptiles seen in the novels and films (which were based on members of the related genus Deinonychus). [2] Today, Velociraptor is well known to paleontologists, with over a dozen described fossil ...
If Deinonychus had feathered fingers and wings, the feathers would have limited the range of motion of the forelimbs to some degree. For example, when Deinonychus extended its arm forward, the 'palm' of the hand automatically rotated to an upward-facing position. This would have caused one wing to block the other if both forelimbs were extended ...
Coelurosauria (/ s ɪ ˌ lj ʊər ə ˈ s ɔːr i. ə /; [3] [4] from Greek, meaning "hollow-tailed lizards") is the clade containing all theropod dinosaurs more closely related to birds than to carnosaurs.
The original definition of Eudromaeosauria was a node-based definition. It was defined as the least-inclusive clade containing Utahraptor ostrommaysi, Velociraptor mongoliensis, Deinonychus antirrhopus, and Saurornitholestes langstoni. The apomorphic features of the group were left unresolved at the time of its naming. [6]
A collection of dromaeosaurid fossil skeletons. Clockwise from upper left: Deinonychus antirrhopus (a heavily built eudromaeosaur), Buitreraptor gonzalezorum (a long-snouted unenlagiine), Velociraptor mongoliensis (a small velociraptorine), Microraptor gui (a winged microraptorian), Halszkaraptor escuilliei (a semiaquatic halszkaraptorine), Zhenyuanlong suni (a long-winged dromaeosaurid)
Archaeopteryx (/ ˌ ɑːr k iː ˈ ɒ p t ər ɪ k s /; lit. ' old-wing '), sometimes referred to by its German name, "Urvogel" (lit. Primeval Bird) is a genus of bird-like dinosaurs.The name derives from the ancient Greek ἀρχαῖος (archaīos), meaning "ancient", and πτέρυξ (ptéryx), meaning "feather" or "wing".
Kirkland et al. noted that given the huge size of Utahraptor, it was not as fast as Deinonychus and Velociraptor; instead, it would have had a similar speed to the contemporary iguanodonts, and was faster than sauropods. Additionally, the thickness of the tibia indicates that the animal possessed a significant leg force in order to kill prey.
Artistic restoration of Deinonychus preying on Zephyrosaurus. This timeline of dromaeosaurid research is a chronological listing of events in the history of paleontology focused on the dromaeosaurids, a group of sickle-clawed, bird-like theropod dinosaurs including animals like Velociraptor.
