When did velociraptor live?

Velociraptor probably lived less than twenty years maximum, maybe as little as 15. Velociraptor was warm blooded, and it was a small carnivore. Small, warm blooded carnivores don't usually live very long today, and theropod dinosaurs, which were related to Velociraptor, such as Tyrannosaurus and Allosaurus, lived less than 30 years.

If you are asking how long the species existed, their fossils date to between 75 and 71 million years ago, meaning that they existed for about 4 million years.
