GENERAL GEOLOGY

Detailed explanation-1: -Brachiosaurus (/ˌbrækiəˈsɔːrəs/) is a genus of sauropod dinosaur that lived in North America during the Late Jurassic, about 154 to 150 million years ago. 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.

Detailed explanation-2: -Description and environment. Brachiosaurus was a sauropod, one of a group of four-legged, plant-eating dinosaurs with long necks and tails and relatively small brains. Unlike other families of sauropods, it had a giraffe-like build, with long forelimbs and a very long neck.

Detailed explanation-3: -Brontosaurus was a large sauropod, a group of typically large dinosaurs with long necks and long tails. It lived during the Late Jurassic Period, from about 156 to 145 million years ago. The first recorded evidence of Brontosaurus was discovered in the 1870s in the USA.

Detailed explanation-4: -Brontosaurus is a sauropod that had forelimbs shorter than its hind legs while Brachiosaurus had longer forelimbs and shorter hind limbs. Additionally, these two gigantic quadruped sauropod dinosaurs differed in tail length.

Detailed explanation-5: -Sauropods and theropods were saurischian dinosaurs. The sauropods evolved into several major subgroups: Cetiosauridae, Brachiosauridae (including Brachiosaurus), Camarasauridae (including Camarasaurus), Diplodocidae (including Diplodocus and Apatosaurus), and Titanosauridae.
