  Possessing a unique foot weapon – a 13 centimetre (5inch) sickle shaped claw; the relatively small Deinonychus was a fearsome killer. Coupled with the fact that it was agile and intelligent for a dinosaur (as shown by the high ratio between brain size and body weight), prey would have had to fight back or run from a hunting pack of Deinonychus. The disembowelling feature of the terrible claw and the ability to rip of large chunks of flesh with the serrated teeth, while the hands held the victim, meant that once caught, escape would have been very difficult.
