VERIFY:weight_max_kg: stored=56000 suggested=46900 confidence=medium — Current mass estimates for the subadult holotype of B. altithorax run from about 28.3 to 46.9 metric tons, following Taylor (2009) and Benson et al. (2014); the stored 56 t upper bound derives from older pre-2009 body models (which assumed 15% larger specimens) that later volumetric work supersedes.

VERIFY:height_min_m: stored=9 suggested=12.5 confidence=low — Standing-height estimates for B. altithorax are generally given as roughly 12.5-15 m, so a 9 m lower bound is materially below the range current reconstructions support; confidence is low because the height figure comes from a compilation rather than a primary description.
