There is a very ominous scene in the Jurassic World trailer that shows a very busy part, filled with tourists, all of whom are fleeing from an unseen threat. Given that the camera angle is from above, this would lead viewers to believe that the threat in question is in the air - a flying dinosaur. But what could it be? Will the pterandons from Jurassic Park III be making a reappearance? Will something new and ever more terrifying - perhaps something bigger like a quetzalcoatlus - be causing havoc on Isla Nublar? Fans will have to wait to find out, but it's very intriguing.
