Both were made from molds made from originals now at the Museum of Geology in South Dakota. The Utah-raptor and Deinonychus claws are from the lethal arsenals of the most deadly dinosaurs to ever stalk the Earth. These vicious sickle claws were truly amazing weapons. Each raptor utilized long arms to subdue a victim, while slashing the abdomen with a ripping claw located on its foot. The original Deinonychus and Utahraptor, from which these replicas were molded, are housed at the Pebody Museum of Natural History, Yale University and the College of Eastern Utah Prehistoric Museum, respectively.
Measurements are of the outside curved side of the claw.
