Partlial skeleton from 2 individuals
Brachiosaurus
is known from all parts of the skeleton except for the important neural
arches of the caudal cervical and cranial dorsal vertebrae and much of
the pes. It was one of the largest sauropods and the one in which the
lengthening of the forelimb relative to the hindlimb reached its
extreme.
Brachiosaurus altithorax was present in the Late Jurassic of North America, Brachiosaurus brancai in eastern Africa.
(B.atalaiensis) Lusotitan atalaiensis from Europe is regarded as a Brachiosauridae due to the low neural spines,
prominent deltopectoral crest of the humerus, elongated humerus, and
the longitudinal axis of the ilium is upward.
The
skull is relativily large, of the general camarasaur type but broader
and with a more elongate snout. The jaws are robust with broad
subspatulate teeth, the crowns convex laterally, concave medially, many
with a median ridge.
