VERIFY:length_max_m: stored=18 suggested=15.5 confidence=high — The most recent full skeletal reconstruction states the adult skeleton is "just under 14 m long", which the authors note is over a metre shorter than the 2014 estimate; other current estimates top out around 15–15.6 m, so a maximum of 18 m is not supported by current peer-reviewed literature.

VERIFY:weight_max_kg: stored=12000 suggested=9000 confidence=medium — The 2022 digital flesh model gives an adult body mass of 7390 kg, and recent volumetric work clusters roughly in the 6–9 tonne range; the older double-digit-tonne figures behind a 12,000 kg maximum have been superseded.
