During the expedition to Isla Sorna, Richard Levine expressed an interest in locating the nest of the Parasaurolophus. He mentioned that he hadn’t been able to locate the nest, and it was never encountered during the course of either expedition to the Island. Part of the reason could’ve been because the animals were secretive, and extraordinarily wary, never straying far from the Apatosaurs.
