Originally part of the type series for Brachiosaurus atalaiensis in addition to lectotype partial skeleton. Hypodigm APK:0/35: Isolated vertebrae from five Portuguese localities.
Lusotitan 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.
