And it's pretty dumb.…

Being a nerd, this part stood out to me:

"No indication of what kind, but there's concept art showing one of the aquatic dino's, as part of a show, jumping out of the lagoon and eating a strung up great white shark like it was a fish for a dolphin at sea world. "

And the nerd in me goes: So... uh, what, this theme park just like, farms great white shark's for this show? Ignoring that'd be illegal at worst and at best something that would subject the park to unnecessary controversy, that... doesn't make a lot of sense. Do they clone the sharks? (That's gotta be expensive.) How do they sustain ably farm a species that's so widespread and notoriously difficult to find? What's even the point? Great white Sharks are scary, sure, but they're not scary suspended in the air helplessly. Why not just use a big commercial fish—like a tuna? Or just a huge chunk of meat?

Other then that, typical retread, although a small part of me does think you could ask some interesting questions and play with some interesting ideas if you let the fictional park become part of the public eye for a while. Just... too bad I doubt we'll be exploring that.
