Oh, and how can Isla Sorna not be mentioned in the Sayles script, the island from the past two movies?
The Pteranodons are presumably the ones from the end of JP3, and when the magical Compies on coconut rafts, along with the other stories, are about to be explained, it's said they're strictly from Isla Nublar.
Not even a quick status update? Grendel was able to secure Nublar for themselves, but what about the bigger production floor with the entire dinosaur ecosystem? Come on.
