Brachiosauridae

Brachiosauridae is represented by Taylor’s character-by-character separation of Brachiosaurus altithorax from Giraffatitan brancai; that genus-level revision does not define the complete family range or every brachiosaurid member. This navigation entry is not a phylogeny or a complete taxon dossier.

Brachiosauridae is displayed at 154.8–145 Ma only as the Late Jurassic type-material comparison for Brachiosaurus and Giraffatitan, not the complete family range. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.
