Jurassic Park Wiki

Utahraptor is the oldest known, and largest, of the dromaeosaurids. At two meters height and seven meters long, they are the size of polar bears. One of the most unique aspects that Utahraptor shares with its more famous cousin Velociraptor is that both had a lethal killing claw on each foot. Each inside toe had a large hooked claw (about 10 inches long) that was controlled by a strong tendon. This claw was held upward when the animal was walking or running. When it attacked, however, the tendon snapped tight and the claw clamped down with great speed and force, slicing deeply into its victim. Not a very pretty picture, but an effective way to inflict a serious wound. Its hand claws were proportionally larger, than other family members and Dr. Kirkland speculates that its hand claws were probably as important a weapon as the killing claws on its feet.[1]

Wikipedia has a more detailed and comprehensive article on Utahraptor

When the movie Jurassic Park was released, dinosaur fans everywhere complained that director Steven Spielberg had made his movie Velociraptors much larger than they were in real life. In the midst of this controversy, Dr. James Kirkland and paleontology student Rob Gaston unearthed the real-life giant raptor that was shown in the movie, only bigger. Utahraptor was huge, and with its big killing claws, strong arms and hands, and sharp teeth, it was one of the most ferocious killers on the planet.[1]

Jody Duncan wrote about this discovery: "Later, after we had designed and built the Raptor, there was a discovery of a Raptor skeleton in Utah, which they labeled 'super-slasher'. They had uncovered the largest Velociraptor to date - and it measured five-and-a-half-feet tall, just like ours. So we designed it, we built it, and then they discovered it. That still boggles my mind."[2]

Jurassic Park (SEGA CD Game)

In Jurassic Park for Sega CD, Utahraptor was mentioned by Dr. Robert T. Bakker for the information on Velociraptor. Since the Raptors are called Utahraptors by Dr. Robert T. Bakker, this must mean that the raptors in the game are Utahraptors.
