Brachiosaurus 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. Riggs named the dinosaur Brachiosaurus altithorax; the generic name is Greek for "arm lizard", in reference to its proportionately long arms, and the specific name means "deep chest".
The Brachiosaurus
Size
The Brachiosaurus was one of the largest dinosaurs to have ever roamed the Earth, reaching lengths of up to 85 feet and towering heights of around 40 feet, making it taller than most giraffes.
Diet
Despite its enormous size, the Brachiosaurus was primarily a herbivore, feeding on a diet of ferns, cycads, and conifers. Its long neck allowed it to reach vegetation high up in trees, giving it a competitive advantage in the Late Jurassic ecosystem.
Habitat
Brachiosaurus likely inhabited floodplain environments, where vegetation was abundant and water sources were plentiful. Fossil evidence suggests that it roamed across what is now North America, with discoveries made in states like Colorado, Utah, and Wyoming.
