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 .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.
In 1966 John Ostrom postulated that the diet of late Cretaceous chasmosaurs such as Triceratops and Torosaurus fed on very resistant and fibrous materials like the fronds of cycad or palm plants. [20] By extension, all Ceratopsids had a shearing dentition and efficient, powerful jaw mechanics that allowed them to feed on tough vegetation.
Gastroliths in some species are retained in the muscular gizzard and used to grind food in animals lacking suitable grinding teeth. In other species the rocks are ingested and pass through the digestive system and are frequently replaced. The grain size depends upon the size of the animal and the gastrolith's role in digestion.
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 ...

As a warm-blooded animal, the daily energy demands of Giraffatitan would have been enormous; it would probably have needed to eat more than 182 kilograms (400 lb) of food per day. If Giraffatitan was fully cold-blooded or was a passive bulk endotherm , it would have needed far less food to meet its daily energy needs.
