Okay, this dinosaur is something special. Seriously, look at the size of this thing. Called the Mamenchisaurus, this is one of the largest animals to ever walk the earth. And now, thanks to the wonders of genetic engineering, it's doing just that again.

Mamenchisaurus is a genus of sauropod dinosaur that originated from Late Jurassic Asia.

Known for their remarkably long necks, which takes up half of their entire body, it is the largest species of dinosaur available to the Hammond Foundation. Mamenchisaurus is first unlocked for operations on the Muertes Archipelago upon completion of the Science Division mission on Isla Sorna.


Originating in China during the Late Jurassic period, Mamenchisaurus was first cloned on Isla Sorna, the factory floor of dinosaur cloning for Jurassic Park on Isla Nublar. A population of four animals was maintained on the island prior to its abandonment in the wake of Hurricane Clarissa in the mid-1990s.[1] Two Mamenchisaurus were briefly encountered in a large herd of herbivorous dinosaurs, by an InGen team sent to the island to round up the animals for a new iteration of Jurassic Park on the mainland.[2]

It is unknown if any Mamenchisaurus were transported to Isla Nublar for Jurassic World upon the collapse of Isla Sorna's ecosystem. As of 2018, it has been revealed that the Mamenchisaurus population was the victim of an unconfirmed form of cruelty.[3]


Mamenchisaurus is an unusual sauropod with a massive swan-like neck and comparatively short tail. The base genome colour is a blotchy greyish brown colour.


Mamenchisaurus is among the largest species of dinosaur available to the Hammond Foundation, and is typical in behaviour to similarly sized sauropods such as Brachiosaurus and Dreadnoughtus. Mamenchisaurus has a relatively low comfort threshold of fifty percent, and can live in social groups of between two and four individuals, and tolerate an enclosure population of up to twenty five different dinosaurs.

With the Claire's Sanctuary expansion pack, Mamenchisaurus can eat from Tall Paleofeeders, showing a preference for Tree Ferns and a secondary preference for Conifers and Ginkgo plants.


Mamenchisaurus is a member of the Mamenchisauridae, a family of sauropods unique to Jurassic Asia and also include Omeisaurus. Members of this family are characterised by their longer neck to tail ratio, giving them a strange yet graceful appearance. It is still unsure why these necks grew so long, though the most likely explanation is to reach higher growth and this avoid competition with other herbivores.


Mamenchisaurus was the largest sauropod in China at this time and was relatively widespread, with fossil evidence suggesting it may have lived in Thailand and the Dashanpu Formation. The Mamenchisaurus lived alongside many other dinosaurs such as the stegosauridae Chungkingosaurus, Gigantspinosaurus, Chialingosaurus, and Tuojiangosaurus, the sauropods Shunosaurus and Omeisaurus, as well as the massive theropod Yangchuanosaurus, which may have been the main predator of Mamenchisaurus.

Behind the scenes

The design of the Mamenchisaurus in Evolution is partially based on the dinosaur's brief appearance in 1997's The Lost World: Jurassic Park. Much like their work on the Ceratosaurus, the development team took some liberties with the movie design of the Mamenchisaurus, and redesigned the animal to some extent to be more scientifically accurate, by giving it an upright posture along with a shorter tail.

It was first revealed when a number of media outlets, influencers, and content creators were invited to Frontier Developments headquarters to play the game and record content just prior to release.[4]
