Сонирхолтой баримтууд

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
