Allosaurus Finger Claw

Allosaurus fragilis was a species of theropod dinosaur known from the Jurassic of modern-day North America. All species of Allosaurus were large carnivores at 2.5 meters tall and nearly 9 meters long. Allosaurus fragilis is one of the most represented dinosaurs in the Morrison Formation, leading paleontologists to hypothesize that Allosaurus may have hunted in groups. One of the most popular Allosaurus specimens is Big Al, a sub-adult with numerous pathologies, which is on display in the University of Wyoming Geological Museum. This specimen shows a finger claw.
