The Brachiosauridae ("arm lizards", from Greek brachion (βραχίων) = "arm" and sauros = "lizard") are a family or clade of herbivorous, quadrupedal sauropod dinosaurs. [1] Brachiosaurids had long necks that enabled them to access the leaves of tall trees that other sauropods would have been unable to reach. [ 2 ]
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.

However phylogenetic studies in the following years failed to find a consensus, with some finding it to lie within Brachiosauridae [6] and others outside of it. [7] In no analysis was the recovered phylogenetic position of Sonorasaurus strongly supported until D'Emic et al. (2016), which found Sonorasaurus to fall confidently within the ...
Already de Lapparent considered the specimen an exemplar of the Brachiosauridae.This was confirmed by a phylogenetic analysis in 2017, showing Vouivria to be a basal member of the Brachiosauridae, placed above Europasaurus and below Brachiosaurus altithorax in the evolutionary tree.
Classification of dinosaurs. Dinosaur classification began in 1842 when Sir Richard Owen placed Iguanodon, Megalosaurus, and Hylaeosaurus in "a distinct tribe or suborder of Saurian Reptiles, for which I would propose the name of Dinosauria."
Padillasaurus was initially classified in the family Brachiosauridae based on its morphology. It had cavities in the sacral vertebrae that had no connection with the hollow interior of the vertebra, therefore lacking a true pleurocoel. This feature links it to the brachiosaurids.
Galvesaurus, or Galveosaurus, (meaning "Galve lizard") is a genus of brachiosaurid sauropod dinosaur from the Late Jurassic period. Fossils of the only known species, G. herreroi, were found in Galve, Spain, hence its generic name, "Galve lizard".
