Brachiosaurus is estimated to have been between 18 and 22 meters (59 and 72 ft) long; body mass estimates of the subadult holotype specimen range from 28.3 to 46.9 metric tons (31.2 to 51.7 short tons). It had a disproportionately long neck, small skull, and large overall size, all of which are typical for sauropods.
Giraffatitan (name meaning "titanic giraffe ") is a genus of sauropod dinosaur that lived during the late Jurassic Period (Kimmeridgian – Tithonian stages) in what is now Lindi Region, Tanzania. Only one species is known, G. brancai, named in honor of German paleontologist Wilhelm von Branca, who was a driving force behind the expedition that ...
Sauropoda (/ sɔːˈrɒpədə /), whose members are known as sauropods (/ ˈsɔːrəpɒdz /; [1][2] from sauro- + -pod, ' lizard -footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs.
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 ...
Lusotitan was a large sauropod, reaching 21 m (69 ft) in length and 30 tonnes (33 short tons) in body mass. [6] It had long forearms with the humerus and femur measuring 2.05 m (6.7 ft) and 2 m (6.6 ft) in length, respectively.
Similar aquatic behavior was commonly depicted for other large sauropods, such as Brachiosaurus and Apatosaurus. A 1951 study by Kenneth A. Kermack indicates that sauropods probably could not have breathed through their nostrils when the rest of the body was submerged, as the water pressure on the chest wall would be too great. [68]
Sauropodomorpha. Sauropodomorpha (/ ˌsɔːrəˌpɒdəˈmɔːrfə / [2] SOR-ə-POD-ə-MOR-fə; from Greek, meaning "lizard-footed forms") is an extinct clade of long-necked, herbivorous, saurischian dinosaurs that includes the sauropods and their ancestral relatives.
