| Alamosaurus, the ‘Alamo Lizard’. I'm probably not the first to ask this, but surely they can't get get any bigger than this… right? If it's alright with you, I’m just going to admire this one from afar. Less chance of getting a crick in my neck that way too, haha! |
Alamosaurus is genus of a sauropod dinosaur in Jurassic World Evolution 2. Originating from Late Cretaceous North America, Alamosaurus is one of the largest dinosaurs ever discovered. It's part of the Late Cretaceous Pack DLC.
Characteristics[]
Among the last non-avian dinosaurs and with shin bones taller than the average human, Alamosaurus was also among the largest dinosaurs, let alone sauropods, known to have ever existed (comparable in size to South American sauropod Argentinosaurus) and therefore the largest dinosaur ever discovered in North America, reaching to a length between 20 and 30 meters and weighing up to 80 tons. Native to North America during the Late Cretaceous period, Alamosaurus (despite being a herbivore) also bore armored spikes on its shoulders, back, and tail that protect it from attacks by predators, making it far from easy prey for any potential predator. The base genome of Alamosaurus is a brown colored body with a lighter brown lateral line and a cream white underside.

Paleontology[]
First discovered in New Mexico by Charles Gilmore, John Reeside and Charles Sternberg in 1921, Alamosaurus skeletons have since been discovered throughout the southern United States. Two years later, the species was officially named Alamosaurus sanjuanensis. Despite the name, the dinosaur is not named after the Alamo in San Antonio, Texas, or the battle that was fought there. Rather than the place, the name Alamosaurus comes from Ojo Alamo, the geologic formation for the Late Cretaceous period in which it was found and, in turn, was named after the nearby Ojo Alamo trading post. The term alamo itself is Spanish for "poplar" and used for the local subspecies of cottonwood tree.
In 1946, Gilmore posthumously described a more complete specimen found on June 15, 1937 on the North Horn Mountain of Utah by George B. Pearce. Since then, hundreds of other fossils from Texas, New Mexico, and Utah have been referred to Alamosaurus, however, without much description. The most completely known specimen is a recently discovered juvenile skeleton from Texas, which allowed educated estimates of length and mass. With this, Almosaurus is estimated to have measured between 26 and 30.5 m (85 and 100 ft) in length, grew to stand around 11 m (36 ft) tall, and weighed 30 to 80 t (66,000 to 176,000 lb), comparable in size to titanic sauropod dinosaurs Argentinosaurus, Dreadnaughtus, and Puertasaurus of South America. This would make Alamosaurus, without a doubt, the largest dinosaur ever known from North America and one of the largest dinosaurs, let alone sauropod dinosaurs, to have ever existed.
Paleoecology[]
Alamosaurus first existed around 83–66 million years ago during the Late Cretaceous period in the southern United States and shared its habitat with many other genera of dinosaur including Ojoraptorsaurus, Torosaurus and the infamous Tyrannosaurus as well as the giant azhdarchid pterosaur Quetzalcoatlus. The genus had large, blunt teeth for stripping trees and other vegetation, while stones found inside the ribcages of some specimens may have been swallowed to help break down fibrous plants. Most likely migrating from South America, Alamosaurus is the first and thus far only known titanosaur, let alone sauropod, discovered to have inhabited North America following the almost 30-million year absence of sauropods from the North American.
