The Dinosaurs of The Lost World and Jurassic Park

Mamenchisaurus is one of the most unique long-necked dinosaurs for a very good reason - it has a really long neck. In fact, it had the longest neck of any creature that ever lived. Stretching [18 metres (59 ft)], the neck on Mamenchisaurus was longer than a school bus! The rest of it was just like other members of its family; a long tail, stout legs and really big.[1]

The architecture of the neck of this dinosaur is incredible. It had 19 neck vertebrae, more than any other dinosaur. The vertebrae had long struts running between them that would have limited the ability of Mamenchisaurus to turn its neck too sharply, but it could still reach well up into the trees to feed. This plant-eater had spatula-shaped teeth that seem to have been well designed to chew coarse plant material. This is one feature that makes it different from the members of the Diplodocidae family, which had peg shaped teeth, to which it has been thought to belong. It is now being thought of as possibly part of a group of sauropods unique to Asia. Most of the big Asian sauropods, such as Omeisaurus, had spatulate teeth. In fact, the Asian sauropods, including Mamenchisaurus, seem to share more characteristics with Brachiosaurus than with Diplodocus. For evidence of this, one needs to look no further than the nose - Mamenchisaurus and other Asian sauropods are very close in evolutionary terms to that of Brachiosaurus. It is also thought that another aspect that these creatures had in common was that they were finding their food high off the ground. Diploducus and Apatosaurus on the other hand were likely feeding on low growing plants.[1]

Jurassic Park SeriesEdit

Mamenchisaurus was only shown in a short scene in The Lost World: Jurassic Park. They are the only sauropods featured in this movie. It also appears in a couple of games. It ultimately replaces Apatosaurus from the second novel.



Mamenchisaurus was recreated by InGen on the island Isla Sorna. For unknown reasons, it was not planned as an attraction in Jurassic Park. After Hurricane Clarissa struck the island, Mamenchisaurus was no longer fed and looked after by humans.



In 1997, during the events of The Lost World: Jurassic Park, InGen's Hunters and Hammond's Gatherers visited the island. When the Hunters started to capture dinosaurs at the Game Trail, two Mamenchisaurs walked out of the forest into the open field. Peter Ludlow was amazed by the enormous size of the animals. One of the Hunters drove between a Mamenchisaurus' legs with a motorbike.

It is unknown if Peter Ludlow captured a Mamenchisaurus for his Jurassic Park in San Diego.

Mamenchisaurus is shown to hold their necks in almost vertical position, inconsistent with modern interpretation of the animal's neck. However it is known that for a short period of time Mamenchisaurus and low browsing sauropods can raise their heads up into the air. This can hold support over the numerous of illustrations and specific skeletal reconstructions of the animals themselves.[citation needed]

Another mistake is that they have a diplodocoid-like head; Mamenchisaurus actually had a round head similar to Camarasauroids.[citation needed]

Video gamesEdit

The Lost World arcade gameEdit


The lost world arcade game


Mamenchisaurus is featured in the arcade game The Lost World: Jurassic Park. In appears in Stage 2 in the Site B Scrub. There is a herd of dinosaurs and you need to drive through without being trampled. First, it lifts its foot and you need to shoot certain spots so it doesn't crush you. You do it again and then the same with the tail, twice. That Mamenchisaurus walks away and there is another one defecating. In order to pass, you need to shoot its dung. If you don't, it'll fling its feces directly at you. The screen will be covered in fecal matter, you will lose a life and the screen will say 'Failed'. The car swerves into a pit of mud, or dung and you will need to fight off raptors.

Jurassic Park III: Park BuilderEdit

Mamenchisaurus is nr. 058 of the Herbivore Threes that can be created in Jurassic Park III: Park Builder.


In the exhibition The Dinosaurs of The Lost World and Jurassic Park the first full-scale Mamenchisaurus was shown.
