Figure 11: In this picture the bipedal stance of Velociraptor
|Velociraptor was a fairly small theropod (about 1.5m in length).
It had a bipedal stance which means it stood upright on two legs. Their
bodies were balanced directly over the pelvis with vertebral column held
nearly horizontally, and the hind legs were held close to the body. Their
ability to function effectively may have come down to the design of their
tail. They had a flexible tail proximally which was stiff distally. This
functioned as a counterbalancing device against the motions of the long
arms and grasping hands. Velociraptor was capable of moving at high
speeds, probably from 40-60 km/hr at top speed. Velociraptor had
fairly hollow bones which lightened the skeleton and increased the strength
of the bones to resist bending.
