| Well, what have we here? It's an Amargasaurus, according to the paperwork I have in front of me. Another interesting factoid: its long neck meant it probably liked to feed on the taller branches of trees and such, at least that's what it said. Guess we'll find out, huh? |
Amargasaurus is a genus of sauropod dinosaur in Jurassic World Evolution 2. Originating from Early Cretaceous South America, it is one of the best-known sauropods due to the spines on its neck.
Characteristics
Named after the site of its discovery, La Amarga Formation in Argentina, Amargasaurus is a sauropod of relatively small size, measuring around 10 meters in length and weighing just under three tons.[1] A member of the Dicraeosauridae family of sauropod dinosaurs, its long neck and sharp teeth allow it to eat tough vegetation from trees, while the two rows of long neural spines that run along its neck and upper back ā forming a double row ā help Amargasaurus to defend itself from predators; an important characteristic given that this dinosaur has poor hearing and is unable to move at high speeds. The base genome of the creature is characterized by dark orange scales on its body, a creamy-colored underbelly, and a slightly gray snout.[1]
Gameplay
Behaviour
Amargasaurus is a peaceful species that can easily coexist with other herbivorous species, whether in small groups or as solitary individuals. Like other sauropods, Amargasaurus primarily eats leaves. However, due to its smaller size, it is unable to feed on tall trees.[1]
Similar to all land dinosaurs in Evolution 2, the Amargasaurus can drink water and rest when fatigued. Occasionally, when idle, the Amargasaurus will take a seated posture. At times, when two Amargasaurus are in close proximity, one may approach the other in an affectionate manner. Their heads may meet, akin to a hug, before they continue walking side by side for a while, until eventually, one of them moves away.
Amargasaurus possesses a natural instinct to flee from any potential predator that attempts to hunt it, despite its slow movement.
Given its reasonable cost and moderate appeal, Amargasaurus can be an efficient dinosaur to incubate when you are starting out your park. Notably undemanding compared to certain sauropods, Amargasaurus is well-suited to smaller enclosures.
Paleontology
Amargasaurus was first discovered in 1984 in Argentina within the sedimentary rocks of the La Amarga Formation, by the same expedition lead by Argentine paleontologist JosĆ© Bonaparte excavating a near-complete skeleton, which also uncovered the single but extremely well-preserved Carnotaurus specimen.[1] Living about 125 million years ago (and thus being far older than Carnotaurus), this is one of the few Cretaceous sauropods known from a complete skeleton. While large compared to a human, Amargasaurus is one of the smaller sauropods, reaching 9 to 13 m (30 to 43 ft) in length and weighing between 2 and 4 t (4,409 and 8,818 lb) ā most of that was neck and tail, and the animal wouldn't be much heavier than a modern rhino. The distinctive row of spines along its neck has been the subject of considerable debate among paleontologists, with some theorizing that it was used for thermoregulation, while others believe they protected the animal from predators.
Amargasaurus was a member of the Dicraeosauridae family, related to Rebbachisaurids such as Nigersaurus and diplodocids such as Diplodocus and Apatosaurus. While not closely related to the giant titanosaurs such as Dreadnoughtus, Amargasaurus was a close relative of Maraapuniasaurus, one of the largest dinosaurs from the Jurassic, known from a giant vertebra long lost to the elements. Despite numerous attempts to unearth more, Bonaparteās discovery is the only Amargasaurus fossil on record.
Paleoecology
Amargasaurus lived in the Early Cretaceous period in the Argentinian La Amarga Formation, a former floodplain and lake ecosystem around 130ā120 million years ago. While numerous other creatures from this formation are identified based on inconclusive remains, crucial elements such as the jaws are absent from the skeleton of Amargasaurus. It existed alongside other sauropods, including Amargatitanis and Zapalasaurus, as well as an indeterminate species of stegosaur and the small ceratosaur theropod Ligabueino. Amargasaurus lived in groups among the woodlands and creeks of South America, migrating regularly in search of food.

Behind the scenes
Amargasaurus stood among the initial dinosaurs to be included in Evolution 2, making its debut in the game's announcement trailer on June 11th, 2021. Subsequently, on June 25th, 2021, it was granted a Species Field Guide. Additionally, an official short article investigating the intricacies of this species was posted on the Frontier forums.[1]
