Velociraptor (/vI’lasIraept@ror “swift seizer” in Latin) is a genus belonging to dromaeosaurid theropod dinosaurs that was present from 75 to 71 million years ago in the final portion of the Cretaceous Period. Two species are recognized currently however other species were assigned previously. The most well-known species can be described as V. mongoliensis. Fossils of this species have been found in Mongolia. Another type, V. osmolskae, was identified in 2008 due to skull bones found in Inner Mongolia, China.
The smaller size of other dromaeosaurids, such as Deinonychus as well as Achillobator, Velociraptor nevertheless shared many of the same anatomical characteristics. Velociraptor was bipedal feathered carnivore, with long tails and an extended sickle-shaped claw on the hindfoot of each foot, which is believed to have been utilized to slash and tear up prey. Velociraptor is distinct from other dromaeosaurids due to its long and low skull, as well as an elongated the snout.
Velociraptor (commonly called “raptor”) is one of the genera of dinosaurs that are most well-known to people in general due to its part within The Jurassic Park motion photo series. In reality however, Velociraptor was about one-third the weight of an adult turkey, and significantly smaller than the 2 meters (6+1/2 feet) tall and weighing around 80 kilograms (180 pounds) reptiles featured on the screen (which were inspired by members of the Genus Deinonychus). In the present, Velociraptor is well known to paleontologists. It has more than twelve fossil skeletons described which is the highest number of any dinosaur. One particular specimen is famous for its preservation of the remains of a Velociraptor engaged in battle with an Protoceratops.
In the course of the American Museum of Natural History excursion in the Outer Mongolian Gobi Desert, on the 11th August of 1923, Peter Kaisen recovered the first Velociraptor fossil that was discovered by scientists that was a mangled but complete skull, which was found in one of the raptorial’s two toe claws (AMNH 6515). In 1924, the museum’s director Henry Fairfield Osborn designated the skull and claw (which was believed to have come out of the palm) as the prototype from his brand new genus Velociraptor. The name derives by the Latin words Velox (‘swift’) and raptor (‘robber or plunderer’) and refers to the animal’s cursorial character and its carnivore diet. Osborn identified the species as V. mongoliensis after its country of its origin. The year before, Osborn had mentioned the animal in a popular newspaper articleunder the title “Ovoraptor djadochtari” (not to be mistaken for the similarly named Oviraptor). However, since the term “Ovoraptor” was not published in a scientific journal nor not accompanied by an official description, it’s considered an unsubstantiated name that is Nudum (‘naked names’), and the name Velociraptor is still the most prominent.
As North American teams were shut out of communist Mongolia during the Cold War, expeditions by Soviet and Polish scientists, working together with Mongolian colleagues, found additional samples of Velociraptor. The most famous of them is part of the well-known “Fighting Dinosaurs” specimen (GIN 100/25) which was discovered by a Polish-Mongolian group in the year 1971. The fossil contains the remains of a Velociraptor in battle with an Protoceratops. This fossil is considered to be to be a national treasure in Mongolia and, in 2000, it was donated by the American Museum of Natural History in New York City for a temporary exhibit.
Between 1988 between 1988 and 1990, a joint Chinese-Canadian team uncovered Velociraptor remains in the northern region of China. American researchers went back to Mongolia in the year 1990, and an expedition of Mongolian-Americans to the Gobi which was under the direction of Norell’s team from the American Museum of Natural History as well as Mongolian Academy of Sciences Mongolian Academy of Sciences, found a variety of well-preserved bones. One such specimen, IGM 100/980, was nicknamed “Ichabodcraniosaurus” by Norell’s team because the fairly complete specimen was found without its skull (an allusion to the Washington Irving character Ichabod Crane). Although Norell and Makovicky had initially thought the specimen to be a member of Velociraptor mongoliensis however, it was designated as an entirely new species, Shri devi in 2021.
Maxillae and lacrimal (the principal tooth-bearing bone in the upper jaw and the bone that creates the anterior edge of the socket for eyes respectively) discovered from the Chinese-Belgian Dinosaur Expeditions were found to be related to Velociraptor but not to the species of type V. mongoliensis. Pascal Godefroit and colleagues named the bone fragments V. osmolskae (for Polish paleontologist Halszka Osmolska) in 2008.
