For those who have everything: A bona fide velociraptor claw

The hit to your bank account would cover the cost of a used car, but it "seems like a small price to beat every other piece of Jurassic Park memorabilia ever," said Chris Mills at Gizmodo. This genuine velociraptor claw ($12,500) is at least 71 million years old. In an office setting, it tells a visitor one thing: "You might just have a trained dinosaur waiting under your desk." Only one such claw is available at New York City's Astro Gallery of Gems, but should someone else scoop up the 6-inch-tall Cretaceous memento, you will have alternatives — like the tooth of a megalodon shark or the foot of a juvenile Edmontosaurus.
