still possible to find fossils and amber at sites that have been exhausted, although they are often of low quality with little DNA to provide. Valuable items such as silver, gold, or opal are also discovered infrequently by the dig team(s), and can be sold for profit. Attractions help make the park popular, and increase its rating power and income when correctly configured. Attractions must be researched before they can be constructed, and include the Balloon Tour, Safari Adventure and Viewing Dome. Viewing Vents and Viewing Platforms do not need to be researched. The Safari Tour and Balloon Tour attractions allow for the player to "take over" the ride for the purpose of park exploration and photography, but only when a visitor in the game is using it. The player may also observe the dinosaurs from the Viewing Dome, Viewing Vent, and Viewing Platform by selecting the "View" option after clicking on the building. Amenities such as restrooms and restaurants are needed for visitors. Additional buildings such as a gift shop and a resting area must be researched before the player can add them into the park. Vaccines for diseasessuch as tick infestation, gastric poisoning, rabies (though only mammals are significantly affected by rabies in real life), and the fictional Dino Flu (possibly a nod to bird flu)must be researched before a sick dinosaur can be treated for a particular illness. Dinosaurs There are a total of 25 species of dinosaurs featured in the game, some of which were featured in the films. The dinosaurs are divided into four main sub-groups. Small herbivores such as Gallimimus and Pachycephalosaurus are easy to care for and do not take up much space, but are not as popular with guests. Large Herbivores such as Brachiosaurus and Triceratops are very popular with visitors and do not require expensive fences, but need large spacious exhibits. Small carnivores such as Dilophosaurus and Velociraptor do not generally need tight security like their larger counterparts, but can still harm guests if they escape. Large carnivores such as Spinosaurus and Tyrannosaurus rex are the most popular dinosaurs in the game, but require large exhibits with high security fences and are prone to rampaging when stressed. Missions The game has 10 missions the player can complete. There are about three or four general types of missions, including taking photographs of dinosaurs to try to rack up a certain number of
