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.
