So, as we all know, carnivores will often kill humans after escaping. The thing is that they kind of just, kill for no reason? They don’t eat the dead bodies, they’re left there. My idea is that if a carnivore does not swallow a person whole and are hungry after the kill, they should be able to eat said person in the same way they can consume the carcass of a dead goat. It would be a nice touch that would make the dinosaurs seem more like actual breathing animals and less like straight up killing machines.
While I haven't played JWE2 yet, in JWE1, carnivores (always smaller / medium size ones) that killed guests but didn't eat them still had their hunger (and health, if applicable) meters increase. I presumed that this was due to Frontier deciding that having the carcass eating animation (where the carnivore pulls out meat chunks) playing over a human corpse would be too distasteful (particularly since they know that a lot of kids will play this game) or might risk increasing the game's content rating from Teen to Mature (or whatever the equivalent is in other countries).
You'll notice that while the large carnivores are shown in the films to eat people onscreen plenty of times, this is never shown for the smaller carnivores, presumable because again, it'd be too graphic / distasteful and might bump the films' content ratings from PG-13 to R (or whatever the equivalent is in other countries).
I don't know if the pterosaurs' hunger (and health, if applicable) meters increase after killing guests in JWE2, but in the Jurassic World films and Camp Cretaceous at least, it can be considered ambiguous as to whether they attack people for food or for territorial reasons. In Jurassic Park III, it's clearly for food since the parent Pteranodon tries to feed Eric to the babies. However, in the Jurassic World films and Camp Cretaceous, the Pteranodons are merely seeing picking people up and dropping them or attacking aircraft. The Dimorphodons aren't really seen attacking single people in numbers that would allow for predation.
