|“||Utahraptor. With lethal claws, this five-metered killer is well armed, and long fingers help them to latch on to swift moving larger prey.||”|
– Kenneth Branagh (Narrator)
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.
- A re-description paper is being written that will drastically change what we know about Utahraptor. Therefore this section is currently removed.
- The Utahraptors of Walking With Dinosaurs have several anatomical inaccuracies. They lack feathers, the head is far too blocky and stout, and the animals have pronated hands. To add, whilst the episode depicts the animals as living in Europe, no fossil evidence has been found of such, with the Utahraptor likely being native to namesake Utah, as that is where fossils have been found.
In Walking with... Series
Utahraptor lived in the Early Cretaceous time period (127-121 MYA), when it hunted in packs, as featured in Walking with Dinosaurs ep. 4. Its' prey included various plant-eating dinosaurs such as European Iguanodon and Polacanthus, also featured in that episode. It was shown to be capable of hunting in packs (or at least family groups) and launching ambushes similar to those of modern lions or similar carnivores. It is possible that the Utahraptor can be considered to be a minor villain or antagonist of Giant of the Skies. In The Making Of episode of the series, after the end credits, a smoking, talking Utahraptor complains about how hard it was for him to work with the animators.
