Utahraptor (meaning “thief from Utah) was a dromeosaurid dinosaur of the theropod family, though at 5–8 meters in length, 2–3 meters in height, and 1000 kilograms in weight, it is the biggest member of its family found so far, much bigger than its later kin, such as the more famous Velociraptor. However, just like the later raptor species, Utahraptor was armed with sickle-like claws on its hind legs and it had self-replenishing teeth in its jaws and also talons on its fingers. Thus, these killers were well armed.
