Peter and his wife Lois treat a hooker in "North by North Quahog" the same way the main characters in Jurassic Park treat a Tyrannosaurus Rex. Peter orders not to make sudden movements or else they'll be spotted.
Peter's line in "German Guy" about "Life always finds a way" is a reference to a line Jeff Goldblum's character said in the film.
Chris acts like the dilophosaurus from Jurassic Park when he spits on Lois in "Tom Tucker: The Man and His Dream".
Stewie's time machine admonishment for Brian in "Yug Ylimaf" parodies Dennis Nedry's in Jurassic Park.
Jack's waving of sparklers and creating a distraction to escape the giant in "Grimm Job" is a parody of a scene in in which a tyrannosaurus is distracted with road flares.
