This is the ~75-million year old Velociraptor claw for sale by the Astro Gallery Of Gems in New York. It measures about six-inches long in total length (including attached bone) and would look amazing hanging from my neck. But like, out the side of my neck with blood gushing everywhere. It's how I want to go.
Thanks to Ben J, who reminds us Velociraptors were only two feet tall and weighed 35 pounds, although there were related species that look similar but grew to over 9-feet tall and weighed 1,000 pounds (i.e. Utahraptor). Why not just use those in the movies? Is it because their name wasn't as cool?
