“Life. It begins. The most precious moment. The result of incalculable actions and reactions, trials and errors, genetic mutations and unknowable combinations, chaos... all leading to a living, breathing thing. An entity. Distinct and unique. And now we... you... just manufacture them. So, well done, I guess.”
Dinosaurs are a group of reptiles which were dominant for 160 million years during the Mesozoic era, from the mid Triassic period to the late Cretaceous period. Dinosaurs are an incredibly diverse group, ranging from modern birds, to the fearsome Tyrannosaurus, to the massive sauropods such as Brachiosaurus and Dreadnoughtus.
In Jurassic World Evolution, the first step in creating a dinosaur is building an Expedition Center, which sends dig teams to dozens of fossil sites across the world to discover dinosaur DNA samples. Once fifty percent viability is reached, dinosaurs can be released into the park via the Hammond Creation Lab, which also allows for the manipulation of dinosaur traits, allowing players to customise the appearance and behaviours of their dinosaurs.
Dinosaurs have several fundamental needs which must be satisfied in order to ensure their health and happiness. In addition to basic food and water needs, different types of dinosaurs can variate greatly in terms of preferred habitat, enclosure size and whether they tolerate other dinosaurs co-existing alongside them. For example, Triceratops enjoy living in medium-sized social groups that consist of five individuals, and can happily live alongside up to fifteen other dinosaurs.
Although non-avian dinosaurs went extinct at the end of the Cretaceous period, 66 million years ago, InGen successfully began cloning dinosaurs in the late 1980s for eventual display in Jurassic Park on Isla Nublar. After the park failed in 1993, the dinosaurs on both Isla Nublar and Isla Sorna were abandoned to the wild, before Masrani Global acquired InGen in 1998, and began development of Jurassic World. After the ecosystem on Isla Sorna collapsed, its surviving dinosaurs were relocated to Nublar, where they were displayed in Jurassic World once it opened to the public in 2005.
After the abandonment of Jurassic World in the wake of the Indominus rex's rampage in 2015, the surviving dinosaurs on Isla Nublar were once again abandoned, and became threatened with extinction once more with the imminent eruption of the island's now-active volcano. Many dinosaurs were eventually rescued from the destruction of Isla Nublar, and were taken to the mainland to be sold off at an auction in Lockwood Manor. Some were successfully bought by the highest bidders, while others were freed from their cages by Maisie Lockwood, to find their way in an unfamiliar world. Simultaneously, cloning technology spread across the globe, no longer limited to InGen and the creation of dinosaur theme parks.
