Mamenchisaurus (/ m ə ˌ m ʌ n tʃ i ˈ s ɔː r ə s / mə-MUN-chee-SOR-əs, Dinosauria Translation and Pronunciation Guide M or spelling pronunciation / m ə ˌ m ɛ n tʃ ɪ ˈ s ɔː r ə s /) is a genus of sauropod dinosaur known for their remarkably long necks [2] which made up nearly half the total body length. [3]
Fossils of Mamenchisaurus and Omeisaurus have been found in the Shaximiao Formation, dating to the Oxfordian-Tithonian interval, around 159-150 Ma (million years ago). Chuanjiesaurus fossils date between 166.1 and 163.5 Ma, while those of Eomamenchisaurus were found in the Zhanghe Formation, believed to be around 175.6-161.2 million years old. [8]
Brachiosaurus (/ ˌ b r æ k i ə ˈ s ɔː r ə s /) is a genus of sauropod dinosaur that lived in North America during the Late Jurassic, about 154 to 150 million years ago. [1] It was first described by American paleontologist Elmer S. Riggs in 1903 from fossils found in the Colorado River valley in western Colorado, United States.
Extrapolations based on the more completely known Brachiosaurus indicate that the head of Sauroposeidon could reach 16.5–18 m (54–59 ft) in height with its neck extended, which would make it one of the tallest known dinosaurs. With an estimated length of 27–34 m (89–112 ft) and a mass of 40–60 t (44–66 short tons), it also ranks ...

Many gigantic forms existed in the Late Jurassic (specifically Kimmeridgian), such as the turiasaur Turiasaurus, the mamenchisaurids Mamenchisaurus and Xinjiangtitan, the diplodocoids Maraapunisaurus, Diplodocus, Apatosaurus, Supersaurus and Barosaurus, the camarasaurid Camarasaurus, and the brachiosaurids Brachiosaurus and Giraffatitan.
Brachiosaurus humerus bone. In 1903, Elmer Samuel Riggs described and named Brachiosaurus. In 1904, he created a new sauropod family, the Brachiosauridae. [9] [1] He published a complete description of the phenotype after examining the humerus, femur, coracoid, and sacrum of the Brachiosaurus holotype that had been prepared at the Field ...
Size comparison of selected giant sauropod dinosaurs (from left to right): Supersaurus, Argentinosaurus, Diplodocus, Mamenchisaurus, and Sauroposeidon. A mega-sauropod, Maraapunisaurus fragillimus (previously known as Amphicoelias fragillimus), is a contender for the largest-known dinosaur in history.
