Brachiosaurus (pronounced BRAC-key-o-saur-us) lived in the late Jurassic period/ the early Cretaceous period. Some of it's fossils have been found in Utah, Colorado, and Lindi (in Tanzania). Brachiosaurus liked to live in canyons, probably because it's so big.
Brachiosaurus was about 29,000 kg.
16 Brachiosaurus specimens have been found. Brachiosaurus was also part of the group called sauropods (long neck dinosaurs). Brachiosaurus is the tallest and heaviest sauropod that has a complete skeleton, meaning that there are taller sauropods, but they are not complete skeletons.
Since Brachiosaurus is so tall, it couldn't eat leaves from bushes, but it would eat leaves from trees.
That is most of the information that we know about Brachiosaurus, thanks for visiting TDT! :D
