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. 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:

Scrapped and missing dinosaurs
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).

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
 * Wuerhosaurus

SPOILERS POSSIBLE!Modding/ Bringing back Scrapped Dinosaurs
In Jurassic Park:Operation Genesis one can make new dinos or get back the scrapped ones. The Deinonychus skin was recycled for Velocioraptor Baryonyx can be made if one renames Spinosaur and removes the sail. Similar is removing Stegosaur's plates to make other herbivores. Iguanodon and Baryonyx still have files in the game. Also one can download skins and change dinosaurs colors. One cheat on it (Named Isla Muerte) skins dinos to look like their dead after rotting for some time. Tyranosaurus has two skins in game. Spoiler warning! Read on at you're own risk! Tyrannosaurus is a 5 star atraction ulockable at anytime. But "TyrranosaurusREX" is a dino that is ulocked at the digsites ulocked after you reach 5 Stars but you must have at least one digsite still locked. 🇨🇴
