While the dinosaurs' modern-day surviving avian lineage (birds) are generally small due to the constraints of flight, many prehistoric dinosaurs (non-avian and avian) were large-bodied—the largest sauropod dinosaurs are estimated to have reached lengths of 39.7 meters (130 feet) and heights of 18 m (59 ft) and were the largest land animals of ...

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.

As loss of filamentous integument is well known in many dinosaur clades, skin impressions and thermodynamic considerations should be given priority over phylogenetic bracketing. Image pose differs appreciably from known range of motion. Example: Theropod dinosaurs reconstructed with overly flexed tails or pronated "bunny-style" hands.
