Utahraptor

Naam beteken: “Utah plunderer”1

Utahraptor was a huge, feathered hunter that lived in what is now Utah, USA. It was the biggest member of the raptor family, much larger than the Velociraptor you see in movies. With a giant sickle claw on each foot, it was a fierce predator that could take down big plant-eaters.1 2

Prettige feite

Utahraptor's sickle claw was 24 centimeters (9.5 inches) long, perfect for slashing at prey.2

It lived during the Early Cretaceous period, about 139 to 135 million years ago, making it one of the oldest known dromaeosaurs.1 2

Utahraptor was the inspiration for the Velociraptors in the movie Jurassic Park, even though real Velociraptor was much smaller.2

In 2018, Utahraptor became the official state dinosaur of Utah after a 10-year-old student asked the state senate.1

Scientists think Utahraptor was not very fast and may have ambushed its prey, using its bulk and claws.1

Although no direct fossils of feathers have been found, scientists believe Utahraptor almost certainly had feathers, like other dromaeosaurs.1

Mite-breker

Mite: Utahraptor was a fast runner like smaller raptors.

Waarheid: Utahraptor was heavy and bulky, and scientists think it was not very fast. It probably used ambush hunting instead of chasing prey.1
