Jurassic Park: Operation Genesis/Dinosaurs

Operation Genesis features twenty-five species of dinosaurs, including thirteen of sixteen that appeared in at least one of the Jurassic Park films. Most of the dinosaurs, however, are based on their look and appearance in Jurassic Park III, even if they were in the previous films. Compsognathus, a major feature in the franchise is notably absent presumably due to its very small size which would have created tremendous logistical problems. Other species missing include two that were shown as embryo species in cold storage in the first film; Metriacanthosaurus and Proceratosaurus, and two others from the Jurassic Park films; Mamenchisaurus and Pteranodon (which was absent alongside any flying reptiles and aviary structures). Each species has its own behavior. Each species is ranked using a star rating (1-5) based on their popularity with the virtual visitors, as well as grouped into one of four major categories based on size and diet:

Revision of the files in the PC version showed that more dinosaur species were planned to be in the game, but got scrapped for unknown reasons. Those species are Alioramus, Deinonychus, Baryonyx, Ornithomimus, Yangchuanosaurus, Diplodocus, Apatosaurus, Iguanodon, Maiasaura, Panoplosaurus, Thescelosaurus, Tenontosaurus and Wuerhosaurus.
