The Lost World Round-Up scene....what it would have been. From the concept art of Jules Kmetzko, the three hadrosaurs: Corythosaurus, Hadrosaurus, and Maiasaura were planned to make an appearance during the round-up scene. It's unfortunate that these dinosaurs were removed from the film's final production, however; the Corythosaurus would later appear in the following sequel (Jurassic Park III), but that Corythosaurus is not the same species. I'll be sure further discuss later in my next project involving the Jurassic franchise.
But it's best to give a least two out of the three hadrosaurs the credit they deserved. Many speculate, Steven Spielberg already had enough dinosaurs for this scene and would distract the audience of the main round-up star Parasaurolophus. However I don't see this problem. So here are both Corythosaurus and Hadrosaurus in the round-up scene.
The Lost World Arcade, is the only role appearance the Anatotitan was featured in.
