Utahraptor (pronounced YOU-tah-RAP-tor) is the largest Dromeaosaur found to date. The only skeletal remains
|Name meaning: Utah's Thief|
|Area: USA (Utah)|
|Period: Late Cretaceous|
|Diet: meat and corpses|
|Lenght: 7m (24ft)|
|Height: 2m (6ft)|
|Weight: 770kg (1700 pounds)|
found are one complete skeleton and several bone fragments and fossils. Nonetheless, these findings suggest that Utahraptor was a real giant. Utahraptor only has one species name, Ostrommaysorum (pronounced Aust-row-may-sor-um)
Utahraptor lived around 112 million years ago in the Early Cretaceous. It was found in Utah, hence the name, Utahraptor, which means Thief of Utah.
Utahraptor was the thickest Dromeaosaur as well as the longest. It weighed up to 1700 pounds (772 kilograms) and 24 feet long (7 meters). Its height varies on what you use as a baseline. It is 6 (somewhere around 2 meters) feet tall at the hips and if it held its neck in a recurved position, was probably around 8 feet tall (about 2.8 meters).
Utahraptor has the normal Dromeaosaur characteristics. Large, 1.8 foot (around .5 of a meter) head with a very advanced brain. Utahraptor had large optic lobes and forwards pointing eyes much like that of an Hawk or Falcon, and its eyes suggest that it was a "chase you down and hunt you" kind of predator. It had short, stocky legs great for jumping, and deadliest of all, a 1 foot (30 centimeters) long killing claw on each toe. That is its main weapon, but it would be happy to use its 5 inch hand claws or sharp teeth. Utahraptor also had a long tail to act as a counterbalance while it runs and helped it to turn faster. Which made the Utahraptor a very efficient swift large agile predator capable of amazing feat.
The top speed of a Utahraptor is debatable, but going off of other dinosaurs of similar sizes who we have a more complete fossil record of, we can say that Utahraptor could run between 25 and 30 mph.
While there is no direct evidence that Utahraptor had feathers, phylogenetic bracketing suggests that it, like all Dromeosaurs, were completely covered in feathers. This is widely accepted among the scientific community.
Stand in the Food Chain Edit
Utahraptor was the top predator of its ecosystem. The only thing bigger than it was Acrocanthosaurus, and it wasn't very common where Utahraptor lived. Utahraptor was bigger than most of its prey too.
Packs and Social Groups Edit
Utahraptor is thought to be a solitary hunter, or at least one that hunts and lives in a family group, but because we've only found one skeleton of it, we can't say for sure until scientists have discovered more about this dinosaus and it's behavior and appearance.
