Utahraptor (meaning "Utah's predator") is a genus of large dromaeosaurid (a group of feathered carnivorous theropods) dinosaur that lived during the Early Cretaceous period from around 135 to 130 million years ago in what is now the United States.
James Ian Kirkland (born August 24, 1954) is an American paleontologist and geologist.He has worked with dinosaur remains from the southwest United States of America and Mexico [1] [2] [3] and has been responsible for discovering new and important genera.
[11] [12] Large size appears to have evolved at least twice among dromaeosaurids; once among the dromaeosaurines Utahraptor and Achillobator, and again among the unenlagiines (Austroraptor, which measured 5–6 m (16–20 ft) long). A possible third lineage of giant dromaeosaurids is represented by isolated teeth found on the Isle of Wight ...

Dromaeosaurus (/ ˌ d r oʊ m i ə ˈ s ɔːr ə s,-m i. oʊ-/; [3] lit. ' running lizard ') is a genus of dromaeosaurid theropod dinosaur that lived during the Late Cretaceous period (middle late Campanian and Maastrichtian), sometime between 80 and 69 million years ago, in Alberta, Canada and the western United States.
Fossils of Tawa-like dinosaurs have also been found in South America, which has important indications about paleogeography. During the Early Jurassic Period, dinosaurs such as Dilophosaurus, Anchisaurus, Coelophysis (formerly known as Megapnosaurus), and the early thyreophoran Scutellosaurus lived in North America.
The Utahraptor, however, was a more accurate dinosaur in size comparison to the franchise's Velociraptors; it was discovered shortly before the 1993 release of Jurassic Park ' s film adaptation. [12] [13] Special-effects artist Stan Winston, who worked on the raptors, joked: "After we created it, they discovered it". [12]
