The Dinosaurs of Jurassic Park
After filming had ended for Jurassic Park, Lessem asked director Steven Spielberg what was to be done with the leftover props used in the film, to which Steven replied "I don't know. You want it?" Lessem then came up with the idea of creating the exhibit as a charitable trust with profits going to the Dinosaur Society to fund dinosaur fossil hunting expeditions from around the world.
The exhibit first opened in conjunction with the movie at the American Museum of Natural History.
The traveling exhibit featured dinosaurs such as Tyrannosaurus rex, Velociraptor, Brachiosaurus, and Struthiomimus, who filled in the role of Gallimimus from the film.
