Utahraptor ostrommaysi is a species of dromaeosaurs that lived in the early part of the Cretaceous. It was discovered by John Ostrom around the Cedar Mountains in Grand County, Utah. The term "raptor" is from the Latin word rapere, to seize.To have an idea of how this animal looked like, think of the velociraptors of Jurassic Park. Actual velociraptors were smaller, but the Utahraptor is about the size of those shown in the movie, standing about six to seven feet in height.As with other dromaeosaurs, paleontologists assume that it was covered in some form of primitive feathers, but no imprints of it have been discovered to validate this. It is thought to have been the largest of the raptors, but lacking the speed its smaller cousins possessed. It's also likely that it was a loner since there is no evidence of it hunting in packs. Regardless, it would have been the apex predator in its area since it had a lethal combination of wits, size and eyesight.
