Despite its popularity, Brachiosaurus is actually a comparatively rare animal, the most complete specimen belonging to a subadult. For this reason, most popular reconstructions of it have been traditionally based on the much more complete African species, but that is no longer considered to belong to the Brachiosaurus genus, having since been assigned to a new genus, Giraffatitan.
