If I recall correctly, the novel's aviary was under some kind of construction, and if I remember there was workers working WITH the whatever Pterosaur was in there.

In a commentary I saw for JPIII, the boat attack in the beginning was supposed to be done by the Pteranodon, but they cut the Pteranodon on screen appearance in the scene. This clearly means they went back for their young, maybe the skull in the Aviary belonged to the Dino-Soar guys, I don't know. Them leaving the Aviary can be explained by them trying to get more food, because living off fish probably wasn't working out for them. Seeing how desperately they attacked the group.

The map was only seen the collector's edition and TellTale's own site, where it was interactive. It doesn't matter where the dinosaurs where, it there purely to show them off as they either appeared in the film or game. Also, look at the Isla Nublar Prop Map and TellTale's map. If you look at the Heliport on the original, it's location isn't the same as TellTale's, but does that make a difference? No. Do you see a big lake where the Brachiosaurs are supposed to be at on the original map? No, it's only TellTale's map. Since JPLegacy's map isn't offical and is fan-made we have no one map of Isla Nublar, so therefore maps contradicting each other is a not a big deal, particularly for TellTale's, as the only locations on that that matter are InGen icons, and visitor's center, which don't contradict anything.
