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.

History

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]

Characteristics

Notable for its incredibly long swan-like neck, which can grow up to 11 meters – almost half of the its overall length – and comparatively short tail, Mamenchisaurus was an unusually large sauropod, one of the largest sauropods to have existed. Its name translates to "Mamenchi Lizard" in reference to the Mamen Brook in Sichuan, China where their remains have been found. This herbivorous dinosaur feeds on plants and leaves, swallowing vegetation whole without the need for chewing. They also possessed large spatula-shaped teeth meaning they could chew plant matter. The base genome colour is a blotchy greyish brown colour.

Behaviour

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.

Paleontology

A partial skeleton of Mamenchisaurus was discovered in 1952 at a construction site for the Yitang Highway in China, although it wasn't formally identified until 1954 when Yang Zhongian (better known as C. C. Young) began studying the fossils that had been found on a construction site – leading to the type name Mamenchisaurus constructus. Further species have been discovered since then.

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.

Paleoecology

By far the largest sauropod in China at its time, Mamenchisaurus existed during the Late Jurassic period, approximately 145-155 million years ago, and was relatively widespread, inhabiting various parts of China. Fossil evidence suggests it may have lived in Thailand and the Dashanpu Formation, which was once a rich forest, likely supported by a nearby lake and river. The variety of finds includes aquatic creatures, as well as numerous sauropods, indicating a diverse ecosystem. Mamenchisaurus tended to feed from large trees, using its long but relatively light neck to reach vegetation that other dinosaurs could not. Mamenchisaurus lived alongside many other dinosaurs such as the stegosauridae Chungkingosaurus, Gigantspinosaurus, Chialingosaurus, and Tuojiangosaurus, fellow 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]
