VERIFY:weight_max_kg: stored=59300 suggested=40000 confidence=high — Bates et al. (2015, Biology Letters) re-evaluated the holotype using 3D convex-hull skeletal modelling and found a mass of roughly 30-40 tonnes, concluding that estimates of 60 tonnes and above are not plausible. The stored 59,300 kg is the superseded Lacovara et al. (2014) scaling-equation figure.

VERIFY:period_end_mya: stored=66 suggested=72 confidence=medium — Detrital zircon U-Pb dating of the Cerro Fortaleza Formation in the region of the Dreadnoughtus quarry constrains those deposits specifically to the Campanian rather than the broader Campanian-Maastrichtian range originally assigned. An end date of 66 Ma (end-Maastrichtian) is therefore too young; the Campanian ends at ~72.1 Ma, consistent with the stored 'campanian' stage and ~78-77 Ma start.
