Velociraptor mongoliensis had a large, curved claw on the second toe of each hind foot. The claw was distinctive, but its outline is not a record of one particular strike. Palaeontologists infer its role from how the toe was built, how the claw was positioned and what rare fossil associations preserve.
A claw held off the ground
The enlarged claw sat on the second toe, while the animal's weight was carried mainly on the other toes. Its raised position would have reduced ordinary contact with the ground and helped keep the sharp tip from wearing down. The foot could still support walking and running without the specialised claw acting like a normal toenail.
The curved shape resembles a hook more than a knife edge. That difference matters: a hook can catch or hold, while a blade is suited to slicing. The skeleton establishes the claw's size and position; it does not preserve the exact movement of the living foot.
What it may have done
Researchers have proposed that the claw helped a dromaeosaurid grip, restrain or injure prey. Some comparisons have been made with modern birds of prey, which use their feet to hold animals. Such comparisons help generate mechanical hypotheses, but a living bird is not a direct behavioural recording of Velociraptor.
For a long time, popular accounts described the claw as a blade that repeatedly cut open prey. A more cautious interpretation treats the foot as a complex gripping and attacking system. The claw may have helped maintain contact with a struggling animal while the jaws and hands also played roles. The fossil record does not show one universal technique.
The Fighting Dinosaurs fossil
A famous Mongolian fossil preserves a Velociraptor and a Protoceratops together in an apparent struggle. The enlarged claw lies close to the other animal. This association is unusually informative because it places the specialised foot beside a potential opponent, and it supports the idea that the claw could be used during close contact.
The fossil does not show every movement that preceded burial. It cannot establish that all Velociraptor individuals hunted in the same way, or that the claw alone caused the encounter's outcome. The position of the two animals, the preserved bones and the circumstances of burial all matter when interpreting the scene.
Why the famous movie version is misleading
Real Velociraptor was smaller than the animals shown in many films and is understood to have had feathers. Its forelimbs were also feathered and mobile, but the enlarged second-toe claw remained one of its most conspicuous features. A compact predator could use specialised feet without being a giant slashing monster.
The claw is therefore best understood as one part of a dromaeosaurid's anatomy. Its shape suggests a role in gripping or attack; the Fighting Dinosaurs fossil supports close interaction with prey or an opponent; neither line alone reconstructs a complete hunt. The language of an “ultimate weapon” goes beyond what the bones can establish.
Frequently asked questions
Which toe carried Velociraptor's sickle claw?
It was the enlarged claw on the second toe of each hind foot. The other toes carried most of the ordinary support while the specialised claw was held clear of the ground.
Did Velociraptor use the claw to slash prey?
A slicing strike is one historical proposal, but the curved claw may also have helped catch, grip or restrain. Fossils do not preserve a full hunting sequence.
What does the Fighting Dinosaurs fossil show?
It preserves a Velociraptor and Protoceratops together, with the sickle claw close to the other animal. Their association supports close contact but cannot reveal every movement or the outcome.
Was Velociraptor as large and bare-skinned as in films?
No. The real animal was much smaller than many movie versions and is understood to have been feathered. Its distinctive claw was real, but its screen portrayal is not a literal reconstruction.
