Illustration of the sacrum of "Brachiosaurus" "nougaredi", unknown material is in grey. The species was assigned to "Brachiosaurus" by its described Lapparent because the small hindlimb and large forelimb would give it an upright posture, supposedly characteristic of "Brachiosaurus". It is now very well known that "B." "nougaredi" is not a species of "Brachiosaurus", but not much has been published on it in recent years. This sacrum is now lost, either somewhere intact in the collections of the NMNH of France, or it was but has now crumbled into dust.
