I always find it funny how they say a real Velociraptor was the size of a turkey, while at the beginning of the first film that kid calls the Raptor a 6ft turkey. Considering how big turkeys can get, and how aggressive they can be, they're already fairly scary, and a carnivorous dinosaur that size would still be pretty scary. Contrariwise, a 6ft turkey would be as bad as any cassowary or theropod dinosaur.
