According to paleontologist Alan Turner,. A lack of quill knobs does not necessarily mean that a dinosaur did not have feathers.

Finding quill knobs on Velociraptor , though, means that it definitely had feathers. This is something we'd long suspected, but no one had been able to prove.

Co-author Mark Norell, Curator-in-Charge of fossil reptiles, amphibians and birds at the American Museum of Natural History , also weighed in on the discovery, saying:.

The more that we learn about these animals the more we find that there is basically no difference between birds and their closely related dinosaur ancestors like velociraptor.

Both have wishbones, brooded their nests, possess hollow bones, and were covered in feathers. If animals like velociraptor were alive today our first impression would be that they were just very unusual looking birds.

According to Turner and co-authors Norell and Peter Makovicky, quill knobs are not found in all prehistoric birds, and their absence does not mean that an animal was not feathered — flamingos , for example, have no quill knobs.

However, their presence confirms that Velociraptor bore modern-style wing feathers, with a rachis and vane formed by barbs.

Based on the spacing of the six preserved knobs in this specimen, the authors suggested that Velociraptor bore 14 secondaries wing feathers stemming from the forearm , compared with 12 or more in Archaeopteryx , 18 in Microraptor , and 10 in Rahonavis.

This type of variation in the number of wing feathers between closely related species, the authors asserted, is to be expected, given similar variation among modern birds.

Turner and colleagues interpreted the presence of feathers on Velociraptor as evidence against the idea that the larger, flightless maniraptorans lost their feathers secondarily due to larger body size.

Furthermore, they noted that quill knobs are almost never found in flightless bird species today, and that their presence in Velociraptor presumed to have been flightless due to its relatively large size and short forelimbs is evidence that the ancestors of dromaeosaurids could fly, making Velociraptor and other large members of this family secondarily flightless, though it is possible the large wing feathers inferred in the ancestors of Velociraptor had a purpose other than flight.

The feathers of the flightless Velociraptor may have been used for display, for covering their nests while brooding, or for added speed and thrust when running up inclined slopes.

Velociraptor is a member of the group Eudromaeosauria , a derived sub-group of the larger family Dromaeosauridae. It is often placed within its own subfamily, Velociraptorinae.

In phylogenetic taxonomy , Velociraptorinae is usually defined as "all dromaeosaurs more closely related to Velociraptor than to Dromaeosaurus.

Originally, the subfamily Velociraptorinae was erected solely to contain Velociraptor. In the past, other dromaeosaurid species, including Deinonychus antirrhopus and Saurornitholestes langstoni , have sometimes been classified in the genus Velociraptor.

Since Velociraptor was the first to be named, these species were renamed Velociraptor antirrhopus and V. When first described in , Velociraptor was placed in the family Megalosauridae , as was the case with most carnivorous dinosaurs at the time Megalosauridae, like Megalosaurus , functioned as a sort of 'wastebin' taxon, where many unrelated species were grouped together.

All dromaeosaurids have also been referred to the family Archaeopterygidae by at least one author which would, in effect, make Velociraptor a flightless bird.

Below are the results for the Eudromaeosauria phylogeny based on the phylogenetic analysis conducted by Currie and Evans in Surprisingly enough, heavy built animals such as Achillobator and Utahraptor were recovered in the Velociraptorinae: [25].

The "Fighting Dinosaurs" specimen, found in , preserves a Velociraptor mongoliensis and Protoceratops andrewsi in combat and provides direct evidence of predatory behavior.

When originally reported, it was hypothesized that the two animals drowned. Burial must have been extremely fast, judging from the lifelike poses in which the animals were preserved.

Parts of the Protoceratops are missing, which has been seen as evidence of scavenging by other animals. The distinctive claw, on the second digit of dromaeosaurids, has traditionally been depicted as a slashing weapon; its assumed use being to cut and disembowel prey.

This suggests Velociraptor may have used its sickle claw to pierce vital organs of the throat, such as the jugular vein , carotid artery , or trachea windpipe , rather than slashing the abdomen.

The inside edge of the claw was rounded and not unusually sharp, which may have precluded any sort of cutting or slashing action, although only the bony core of the claw is preserved.

The thick abdominal wall of skin and muscle of large prey species would have been difficult to slash without a specialized cutting surface.

The producers of the program created an artificial Velociraptor leg with a sickle claw and used a pork belly to simulate the dinosaur's prey.

Though the sickle claw did penetrate the abdominal wall, it was unable to tear it open, indicating that the claw was not used to disembowel prey.

Remains of Deinonychus , a closely related dromaeosaurid, have commonly been found in aggregations of several individuals.

Deinonychus has also been found in association with the large ornithopod Tenontosaurus , which has been cited as evidence of cooperative pack hunting.

Dromeosaur footprints in China suggest that a few other raptor genera may have hunted in packs, but there have been no conclusive examples of pack behavior found.

In , Denver Fowler and colleagues suggested a new method by which dromaeosaurs like Velociraptor and similar dromaeosaurs may have captured and restrained prey.

This model, known as the "raptor prey restraint" RPR model of predation, proposes that dromaeosaurs killed their prey in a manner very similar to extant accipitrid birds of prey : by leaping onto their quarry, pinning it under their body weight, and gripping it tightly with the large, sickle-shaped claws.

These researchers proposed that, like accipitrids, the dromaeosaur would then begin to feed on the animal while it was still alive and prey death eventually resulted from blood loss and organ failure.

This proposal is based primarily on comparisons between the morphology and proportions of the feet and legs of dromaeosaurs to several groups of extant birds of prey with known predatory behaviors.

Fowler found that the feet and legs of dromaeosaurs most closely resemble those of eagles and hawks , especially in terms of having an enlarged second claw and a similar range of grasping motion.

The short metatarsus and foot strength, however, would have been more similar to that of owls. The RPR method of predation would be consistent with other aspects of Velociraptor ' s anatomy, such as their unusual jaw and arm morphology.

The arms, which could exert a lot of force but were likely covered in long feathers, may have been used as flapping stabilizers for balance while atop a struggling prey animal, along with the stiff counterbalancing tail.

The jaws, thought by Fowler and colleagues to be comparatively weak, would have been useful for row saw motion bites like the modern day Komodo dragon , which also has a weak bite, to finish off its prey if the kicks weren't powerful enough.

These predatory adaptations working together may also have implications for the origin of flapping in paravians.

The endocranium examinations also further cemented the theory that the dromaeosaur was an agile, swift predator. Fossil evidence suggesting Velociraptor scavenged also indicates that it was an opportunistic and actively predatory animal, feeding on carrion during times of drought or famine, if in poor health, or depending on the animal's age.

In , Hone and colleagues published a paper on their discovery of shed teeth of what they believed to be a Velociraptor near a tooth-marked jaw bone of what they believed to be a Protoceratops in the Bayan Mandahu Formation.

This was interpreted as showing scavenging behaviour. Velociraptor was warm-blooded to some degree, as it required a significant amount of energy to hunt.

Modern animals that possess feathery or furry coats, like Velociraptor did, tend to be warm-blooded, since these coverings function as insulation.

However, bone growth rates in dromaeosaurids and some early birds suggest a more moderate metabolism , compared with most modern warm-blooded mammals and birds.

The kiwi is similar to dromaeosaurids in anatomy, feather type, bone structure and even the narrow anatomy of the nasal passages usually a key indicator of metabolism.

The kiwi is a highly active, if specialized, flightless bird, with a stable body temperature and a fairly low resting metabolic rate, making it a good model for the metabolism of primitive birds and dromaeosaurids.

One Velociraptor mongoliensis skull bears two parallel rows of small punctures that match the spacing and size of Velociraptor teeth.

Scientists believe that the wound was likely inflicted by another Velociraptor during a fight. Further, because the fossil bone shows no sign of healing near the bite wounds, the injury probably killed it.

From evidence on the pterosaur bones, which were devoid of pitting or deformations from digestion, the Velociraptor died shortly after, possibly from the earlier injury.

All known specimens of Velociraptor mongoliensis were discovered in the Djadochta Formation also spelled Djadokhta , in the Mongolian province of Ömnögovi.

Species of Velociraptor have also been reported from the slightly younger Barun Goyot Formation of Mongolia, [41] though these are indeterminate and may belong to a related genus instead.

The type specimen was discovered at the Flaming Cliffs site also known as Bayn Dzak and Shabarakh Usu , [1] while the "Fighting Dinosaurs" were found at the Tugrig locality also known as Tugrugeen Shireh.

All of the fossil sites that have yielded Velociraptor remains preserve an arid environment with fields of sand dunes and only intermittent streams , although the younger Barun Goyot environment seems to have been slightly wetter than the older Djadochta.

Many of the same genera were present across these formations, though they varied at the species level. For example, the Djadochta was inhabited by Velociraptor mongoliensis , Protoceratops andrewsi , and Pinacosaurus grangeri , while the Bayan Mandahu was home to Velociraptor osmolskae , Protoceratops hellenikorhinus , and Pinacosaurus mephistocephalus.

These differences in species composition may be due a natural barrier separating the two formations, which are relatively close to each other geographically.

Other dinosaurs known from the same locality as V. Velociraptor are well known for their role as vicious and cunning killers thanks to their portrayal in the novel Jurassic Park by Michael Crichton and its film adaptation , directed by Steven Spielberg.

The "raptors" portrayed in Jurassic Park were actually modeled after the closely related dromaeosaurid Deinonychus. Paleontologists in both the novel and film excavate a skeleton in Montana , far from the central Asian range of Velociraptor but characteristic of the Deinonychus range.

Crichton used the controversial taxonomy proposed by Gregory S. Momentan werden zwei Arten anerkannt: Die Typusart Velociraptor mongoliensis , deren fossile Knochen in der Mongolei und der Inneren Mongolei China gefunden wurden, sowie die beschriebene, bisher nur durch Schädelmaterial aus der Inneren Mongolei bekannte Art Velociraptor osmolskae.

Mit über einem Dutzend entdeckten fossilen Skeletten ist Velociraptor einer der am besten untersuchten Dromaeosauriden. Ein besonders populäres Fossil zeigt Velociraptor mit einem Protoceratops ; beide Tiere starben augenscheinlich während eines Kampfes.

Ein Unterscheidungsmerkmal zu anderen Dromaeosauriden ist die lange, flache und leicht nach oben gebogene Schnauze.

Der breiten Öffentlichkeit bekannt geworden ist Velociraptor insbesondere wegen seiner von künstlerischer Freiheit geprägten Rolle als intelligentes menschenfressendes Raubtier in der Jurassic-Park -Filmserie.

Der vordere Abschnitt der Schnauze war leicht nach oben gebogen, was zu einer konkaven Schnauzenoberseite und einer konvexen Unterseite führte.

Die Augen waren nach vorne gerichtet, was ein gutes räumliches Sehen ermöglichte. Das Handskelett ähnelte in seiner Struktur und Flexibilität dem der Vögel und zeigte drei stark gekrümmte Krallen.

Der zweite Finger war der längste Finger, der erste Finger der kürzeste. Aufgrund der Struktur der Handwurzelknochen war die Pronation Einwärtsdrehung des Handgelenks unmöglich.

Dies zwang Velociraptor dazu, seine Hände stets mit der Handflächenseite nach innen zu tragen. Sie wurde vermutlich als Waffe bei der Jagd eingesetzt.

Extrem verlängerte Knochenfortsätze zur Verbindung der Wirbel Präzygapophysen an den Wirbelbögen, verlängerte Chevron-Knochen an der Unterseite der Wirbel sowie verknöcherte Sehnen versteiften den Schwanz des Velociraptor.

Die Präzygapophysen waren ab dem zehnten Schwanzwirbel ausgebildet und erstreckten sich in rutenartigen Bündeln, in Abhängigkeit von ihrer Position vier bis zehn Wirbel überspringend, nach vorn.

Die Anpassungen des Schwanzes waren vermutlich vorteilhaft, um in Kurven mit hoher Geschwindigkeit Balance und Stabilität zu wahren.

Im Jahre wurden an einem gut erhaltenen Vorderarmknochen von Velociraptor Ansätze für Federkiele gefunden, womit eine Befiederung bei Velociraptor bestätigt ist.

Während nordamerikanischen Forschern im Kalten Krieg keine Einreise in die kommunistische Mongolei gestattet war, entdeckten sowjetische, polnische und mongolische Forscher weitere Skelette.

Zwischen und entdeckte ein chinesisch-kanadisches Team Überreste von Velociraptor in Nordchina. Die meisten Fossilien von Velociraptor mongoliensis wurden in der Djadochta-Formation gefunden, sowohl im mongolischen Aimag Ömnö-Gobi als auch in der chinesischen Inneren Mongolei.

Bislang noch nicht einer der beiden Arten zugeordnete Fundstücke von Velociraptor stammen auch aus der etwas jüngeren Barun-Goyot-Formation der Mongolei.

Die Landschaft war durch saisonal austrocknende Gewässer und Sanddünen geprägt, und das Klima glich dem der heutigen wechselfeuchten Tropen.
