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 ...
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".

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)
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.
Life restoration of Kuru based on related taxa. Kuru is a small-bodied eudromaeosaur, similar in size to Velociraptor.The holotype specimen is known from an incomplete skeleton that is overall similar to other known eudromaeosaurs, indicating that in life it would have resembled its better-understood relatives like Velociraptor and Tsaagan.
A size comparison diagram between a real-life Velociraptor (green) and a Velociraptor from Jurassic Park (orange) alongside a human (blue) Real Velociraptors measured approximately 2 feet (0.61 m) in height and 6 feet (1.8 m) in length. [9] The franchise, however, depicts the animal as being larger than its real-life counterpart.
