The reason I asked was this in the scene of Jurassic Park III when the group attempts to reach a barge docked in a nearby river. They are forced to pass through a massive aviary and are attacked by Pteranodons. Using the para glider he salvaged, Billy tries to rescue Eric from a nest of Pteranodon chicks and is attacked by several adults. He plunges into the river as they continue to attack him, seemingly killing him. It would be the same situation, but instead of Eric it would be both Littlefoot and Chomper and the Flying Dinosaurs can't be Pteranodons (because Petrie is a Pteranodon), get what I'm saying?
