velociraptor coloring page The name Velociraptor was given by Henry Fairfield Osborn who was president of the American Museum of Natural History in 1924.
Velociraptor comes from “Velox” (fast) and “raptor” (robber or looter), which describe his tactics for survival.
Previously, Osborn referred to this dinosaur as Ovoraptor djadochtari before moving on to the current name.
There are two types of Velociraptor. First, the fossil of the V. mongoliensis species was found in Mongolia.
The second species, V. osmolskae, was named in 2008 for the skulls found deep in Mongolia.
Included in the dromaeosaurid family, Velociraptor was the size of a turkey and was the smallest of the members of the same family as Deinonychus and Achillobator.
An adult Velocariptor can grow up to 2 meters long and 0.5 meters high and weigh 15 kilograms.
Like the Tyrannosaurus rex, Velociraptor played an important role in the film “Jurassic Park”, although scientists did not believe its portrayal in the film in terms of both size and appearance.
While in the hairless Velociraptor film, paleontologists discovered a well-preserved limb growth site in Mongolia in 2007.
These feathers are thought to merely serve to attract mates, regulate body temperature, and help females protect eggs because Velociraptor does not fly.
Although many of their related ancestors to the Velociraptor were able to fly, they are thought to have remained above the ground due to their disproportionate weight to their short forelimbs.
Although they shared many of the same physical characteristics with other dromaeosaurs, the distinctive features that distinguished the Velociraptor included a long skull shape that was concave on the top surface and convex on the bottom.
The jaws have 26 to 28 teeth on each side, with the back more serrated, making them ideal for grasping and gripping moving prey.
The tail of the Velociraptor consisted of fused, inflexible hard bones, much more so as a counterweight to running or jumping.
Scientists estimate the Velociraptor can jump as high as 3 meters in the air.
Velociraptor, like other dromaeosaurids, had two hand-like features that had three curved claws.
Claws are used in the same way as birds use claws, which are to grip the prey so it does not escape.
The sickle-shaped retractable (inserted) claws on each hind leg may be used to kill the prey by piercing its throat.
The nickname “fast thief” can be a bit misleading. The Velociraptor might be able to run up to a speed of 60 km / h on its two hind legs, but it could only last a short time.
Velociraptor food As carnivores, it is believed that Velociraptor preyed on small animals such as reptiles, amphibians, and other small dinosaurs.
The herbivorous horned dinosaur, Protoceratops, is thought to have been the Velociraptor’s favorite food.
Fossil Discovery The first Velociraptor fossils were discovered by Peter Kaisen on the first expedition of the American Museum of Natural History on the edge of the Gobi Desert, Mongolia, in August 1923.
The skull found was crushed but complete and contained foot claws.
In all, about a dozen Velociraptor fossils of the V. mongoliensis species have been found in the Djadochta formation, in the Mongolian province of Omnogovi.
While the North American team was not allowed to enter communist Mongolia during the Cold War, Soviet and Polish scientists in collaboration with Mongolian scientists went on an expedition and found several more Velociraptor specimens.
On one expedition in 1971, the Polish-Mongolian team found Velociraptor and Protoceratops fossils while fighting. This fight was preserved by a dune that collapsed on them.
Between 1988 and 1990, a Chinese-Canadian team managed to find Velociraptor fossils in northern China.
In 1990, a joint Mongolian-American expedition to the Gobi, led by the American Museum of Natural History and the Mongolian Academy of Science again recovered several well-preserved Velociraptor skeletons.
