Utahraptor ostrommaysorum (dromaeosaur), foot Grand County, Utah 1990 Cast

This foot and deadly sickle claw once belonged to Utahraptor, cousin to Velociraptor of Jurassic Park fame. Scientists believe Utahraptors used this hooked claw to slice open prey, causing death or serious injury. In the 1990’s, several bones from this ferocious predator were discovered near Arches National Park about the time the first Jurassic Park hit movie theaters.
