Raptors came in all different shapes and sizes. The ones in the video above were probably comparable to Utahraptor, about 20 feet long and 6ft tall. From this you can see where the Jurassic Park's Velociraptors came from.
To be honest Velociraptor was a pussy. It was the size of a turkey for goodness sake. Deinonychus and especially Utahraptor were the true predators. Utahraptor had a killing claw 24cm long!
Utahraptor was one of the earliest of the Raptors, living 120 million years ago in the early Cretaceous period of North America.Unlike other Raptors Utahraptor had much thicker legs that were more robust. This suggests that Utahraptor was very powerfully built, unable to run fast, but well adapted take down large slow moving prey. The leg bones were even twice as thick as those of Allosaurus, an animal twice the size of Utahraptor.
Utahraptor was probably a predator of the large long necked Brachiosaurs , using its massively powerful legs to leap at its prey, clinging onto its back and inflicting deep wounds with its killing claws as it used them to grip onto the animals flanks.
So why is Utahraptor the Jurassic Albatross mascott? Well for starters it had feathers. Raptors from China have been found with feathers preserved on their bodies, suggesting Utahraptor had them too. Therefore it fits in with the albatross/ bird catergory. Also because it is prehistoric, as the word Jurassic suggests. Finally because Raptors are cool and Utahraptor is the biggest. I will prepare a suitable image right away.
