Like all theropods velociraptor walked on 2 legs.
There are over a dozen described skeletons of Velociraptor. There are more described skeletons of Velociraptor than there are of any other dromaeosaur.
The Greek name for velociraptor is "velociraptor" (βελοκιράπτορας).
Velociraptor was 6 feet, or almost 2 meters, in length. They were only about 2 feet tall.
The scientific name for a velociraptor is velociraptor monogoliensis.
The cervical spine is made up of seven cervical vertebrae. These are numbered(C1-C7) and are the smallest of the true vertebrae. The third through sixth cervical vertebrae have characteristics in common. The first, second, and seventh are considered special cervical vertebrae, and have different characteristics.
Overall, sacral vertebrae problems are not common in horses. However, it is possible for the sacral vertebrae to become fractured, dislocated or infected, all of which can compress the pelvic limb spinal nerves that run through the sacral vertebrae.
Protoceratops had many predators, such as Oviraptor and Velociraptor.

First, you should note that it's actually spelled "velociraptor". Anyway, velociraptor is commony reffered to as just "raptor" because of the fame that name gained in Jurassic Park. As far as I know, there is no official common name.
Velociraptor belonged to the family Dromaeosauridae. There were many species in this family that were larger than Velociraptor, but the largest was Utahraptor. Utahraptor grew to be 23 feet long and weighed between 1,100 and 2,200 lb.
